This application relates to the field of communication technologies, and specifically relates to a media file play method and apparatus, an electronic device, a server, and a medium.
With development of communication technologies, electronic devices are increasingly widely used.
Currently, a user may play a media file by using an electronic device. Specifically, the user may tap a multimedia application icon to trigger the electronic device to display a multimedia application play interface, and the user performs an operation on the play interface to trigger the electronic device to download a media file from a server and play the media file.
However, in some cases, because there may be duplicate segments in the foregoing media file (for example, duplicate actions in a moving video), if the foregoing manner is used, the electronic device may download the duplicate segments from the server again, resulting in a waste of traffic.
Embodiments of this application aim to provide a media file play method and apparatus, an electronic device, a server, and a medium.
According to a first aspect, an embodiment of this application provides a media file play method, and the method includes:

According to a third aspect, an embodiment of this application further provides a media file play apparatus, and the apparatus includes:
According to a fourth aspect, an embodiment of this application further provides a media file play apparatus, and the apparatus includes:
According to a fifth aspect, an embodiment of this application provides an electronic device. The electronic device includes a processor, a memory, and a program or an instruction that is stored in the memory and that can be run on the processor, where when the program or the instruction is executed by the processor, the steps of the method in the first aspect are implemented.
According to a sixth aspect, an embodiment of this application provides a server, where a program or an instruction is stored on the server, and the program or the instruction is executed by a processor to implement the steps of the method in the second aspect.

In the embodiments of this application, a server stores a target configuration file corresponding to a target media file, where the target media file includes a plurality of segments, and the plurality of segments include a first segment and a second segment; and the target configuration file includes a plurality of pieces of index information, the plurality of pieces of index information include first index information and second index information, and the first index information and the second index information are respectively used to indicate the first segment and the second segment in the target media file, where a play sequence of the first segment is earlier than a play sequence of the second segment. When an electronic device requests the server to play the target media file, after downloading the first segment from the server and playing the first segment based on the first index information, the electronic device may cache the first segment in a cache apparatus of the electronic device. When the second segment is played, if index information of the second segment is the same as index information of the first segment, that is, the second index information is the same as the first index information, it indicates that the second segment and the first segment are duplicate segments with duplicate content. Therefore, the electronic device does not need to download the second segment from the server again, but only needs to retrieve, from the cache apparatus of the electronic device based on the first index information, the first segment associated with the first index information, and play the first segment, to achieve a purpose of playing the second segment, without requiring the electronic device to download the second segment that duplicates the first segment from the server again. In this way, in a process of playing the target media file with duplicate segments, the electronic device does not need to repeatedly download the content duplicate segments from the server, thereby saving traffic of playing the media file with duplicate segments.
The following describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application.

Any embodiment or design scheme described as “an example of” or “for example” in the embodiments of this application should not be explained as being more preferred or having more advantages than another embodiment or design scheme. Exactly, use of the term “example” or “for example” is intended to present a concept in a specific manner.
A media file play method provided in the embodiments of this application may be performed by a media file play apparatus. The apparatus may be the foregoing electronic device (including a mobile electronic device and a non-mobile electronic device), a server that establishes a connection to the foregoing electronic device, or a function module and/or a function entity in the electronic device and the server and can implement the media file play method. In some embodiments, this may be determined according to an actual use requirement, and is not limited in the embodiments of this application. The media file play method provided in the embodiments of this application may be applied to a scene in which the electronic device requests a server to play a media file with duplicate segments, for example, a scene in which the electronic device requests the server to play a media file with synchronously duplicate audio and video, or a scene in which the electronic device requests the server to play a media file with asynchronously duplicate audio and video.
In the embodiments of this application, a server stores a target configuration file corresponding to a target media file, where the target media file includes a plurality of segments, and the plurality of segments include a first segment and a second segment; and the target configuration file includes a plurality of pieces of index information, the plurality of pieces of index information include first index information and second index information, and the first index information and the second index information are respectively used to indicate the first segment and the second segment in the target media file, where a play sequence of the first segment is earlier than a play sequence of the second segment. When an electronic device requests the server to play the target media file, after downloading the first segment from the server and playing the first segment based on the first index information, the electronic device may cache the first segment in a memory of the electronic device. When the second segment is played, if index information of the second segment is the same as index information of the first segment, that is, the second index information is the same as the first index information, it indicates that the second segment and the first segment are duplicate segments with duplicate content. Therefore, the electronic device does not need to download the second segment from the server again, but only needs to retrieve, from the memory of the electronic device based on the first index information, the first segment associated with the first index information and play the first segment, to achieve a purpose of playing the second segment, without requiring the electronic device to download the second segment that duplicates the first segment from the server again. In this way, in a process of playing the target media file with duplicate segments, the electronic device does not need to repeatedly download the duplicate segments from the server, thereby saving traffic of playing the media file with duplicate segments.
With reference to
For example,
In this embodiment of this application, the server may be a computer device that manages resources and provides a service for the electronic device. The server may include a processor, a hard disk, a memory, a bus, and the like.
In this embodiment of this application, the electronic device may send, to the server, a first request message for requesting to play a target media file. After receiving the first request message, the server may first send a target configuration file including index information of each segment in the target media file to the electronic device, that is, the electronic device obtains the target configuration file sent by the server, and then the electronic device may obtain a cached segment from the electronic device based on the index information in the target configuration file, or download, from the server, a segment that is not cached in the electronic device.
In this embodiment of this application, the electronic device may be a mobile electronic device, or may be a non-mobile electronic device. The mobile electronic device may be a mobile phone, a tablet computer, a laptop computer, a palmtop computer, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), or the like. The non-mobile electronic device may be a personal computer (PC), a television (TV), an automated teller machine, a self-service machine, or the like. This is not specifically limited in this embodiment of this application.
The electronic device in this embodiment of this application may be an electronic device with an operating system. The operating system may be an Android operating system, an iOS operating system, or another operating system. This is not specifically limited in this embodiment of this application.
Based on the communication system shown in
Step 201: An electronic device sends a first request message to a server.
The first request message is used to request to play a target media file, the target media file includes a first segment and a second segment, and a play sequence of the first segment is earlier than a play sequence of the second segment.
The first request message may be used to request to play the target media file. It can be understood that the first request message may be used by the electronic device to request the target media file from the server.
In this embodiment of this application, the electronic device may send the first request message to the server in the following two manners:
In a first manner, the electronic device may send the first request message to the server based on a play request operation performed by a user and in response to the play request operation. That is, the electronic device may send the first request message to the server when triggered by the user.
For example, the first request message may be sent when the user triggers the play request operation on the target media file in a target application. For example, the first request message may be sent when the user triggers an operation on a play key on a play interface of the target application.
In this embodiment of this application, the target application may be a multimedia application in the electronic device, such as a video application, an audio application, or another application that may play an audio file and/or a video file. This may be determined according to an actual use requirement, and is not limited in this embodiment of this application.
In a second manner, the electronic device may automatically send the first request message to the server.
For example, the electronic device may be installed with a video application. After entering a play interface of the video application, the electronic device automatically plays a recommended video on the play interface. That is, after entering the play interface, the electronic device automatically sends, to the server, the first request message for playing the recommended video.
In this embodiment of this application, the target media file may be an audio media file (that is, include audio), a video media file (that is, include a video), or an audio and video media file (that is, include audio and a video).
In this embodiment of this application, the target media file may include a plurality of segments, and the plurality of segments include at least the first segment and the second segment. The play sequence of the first segment is earlier than the play sequence of the second segment, that is, the second segment is played only after the electronic device plays the first segment.
In this embodiment of this application, the first segment and the second segment may be content duplicate segments, or may be segments with different content.
In this embodiment of this application, in a case that the target media file is an audio media file (that is, includes only audio), the first segment and the second segment are also an audio media file. In a case that the target media file is a video media file (that is, includes only a video), the first segment and the second segment are also a video media file. In a case that the target media file is an audio and video media file (that is, includes audio and a video), the first segment and the second segment are also an audio and video media file.
Step 202: The server receives the first request message.
In this embodiment of this application, after the electronic device sends the first request message to the server, the server may receive the first request message sent by the electronic device. After the server receives the first request message, the server may obtain, based on the first request message, a target configuration file of the target media file indicated by the first request message.
A method for obtaining the target configuration file of the target media file by the server is described in detail in the following embodiment, and details are not described herein.
Step 203: The server sends a target configuration file to the electronic device.
The target configuration file includes first index information and second index information, the first index information is used to indicate the first segment, and the second index information is used to indicate the second segment.
In this embodiment of this application, the server may store a plurality of media files, each media file is configured with a configuration file, and these configuration files are all stored in the server. When the electronic device requests the server to play a media file such as the target media file, the server may first send the target configuration file corresponding to the target media file to the electronic device in response to a play request of the electronic device for the target media file.
In this embodiment of this application, the target configuration file may include a plurality of pieces of index information, the plurality of pieces of index information include at least the first index information and the second index information, and each piece of index information may be used to indicate one segment in the target media file. For example, the first index information is used to indicate the first segment and the second index information is used to indicate the second segment. The target configuration file may be used by the electronic device to download each segment of the target media file from the server before playing the target media file.
In this embodiment of this application, in an implementation, the server may perform slice processing on the target media file to obtain a plurality of slice files (for example, the first segment and the second segment in this embodiment of this application), and the server configures one piece of index information for each segment. Then, the server may splice the plurality of pieces of index information into one list file (for example, the target configuration file in this embodiment), and store the target configuration file in the server.
In another implementation, the server may further receive the target configuration file uploaded by a media file provider. In some embodiments, the electronic device of the media file provider may first perform slice processing on the target media file to obtain a plurality of slice files (for example, the first segment and the second segment in this embodiment of this application), and the electronic device of the media file provider configures one piece of index information for each of the plurality of segments, and then splices the plurality of pieces of index information into one list file (for example, the target configuration file in this embodiment). Then, the electronic device of the media file provider may upload the target configuration file to the server, and after receiving the target configuration file, the server may store the target configuration file in the server.
In still another implementation, the electronic device of a media file provider may first perform slice processing on the target media file to obtain a plurality of slice files (for example, the first segment and the second segment in this embodiment of this application), and then send the plurality of segments to the server. After receiving the plurality of segments, the server configures one piece of index information for each segment. Then, the server may splice the plurality of pieces of index information into one list file (for example, the target configuration file in this embodiment), and store the target configuration file in the server.
In this embodiment of this application, the target configuration file may be configured as a file in an M3U8 format. The M3U8 file is essentially an M3U file (Moving Picture Experts Group Audio Layer 3 Uniform Resource Locator), and the M3U file is similar to directory information of an audio file, a video file, and an audio and video file.
It should be noted that the M3U8 file is not an audio file, a video file, or an audio and video file, but a list file of an audio file, a video file, and an audio and video file. After the electronic device opens the M3U8 file, the electronic device does not directly play the M3U8 file, but first obtains corresponding index information based on the M3U8 file, and then downloads and plays a corresponding segment.
In this embodiment of this application, the plurality of pieces of index information are greater than or equal to two pieces of index information.
In this embodiment of this application, the index information may be a Uniform Resource Locator (URL), and the URL is used to locate a resource by using an abstract identifier that provides a resource location. The index information may be storage path information, or index information in any other form. This may be determined according to an actual use requirement, and is not limited in this embodiment of this application.
It can be understood that, in this embodiment of this application, the foregoing same index information may be understood as that key values of URLs are the same, that is, URLs that have a same key are used to locate a same address; or the foregoing same index information may be understood as same storage path information.
Step 204: The electronic device receives the target configuration file.
In this embodiment of this application, after the electronic device receives the target configuration file sent by the server, the electronic device may play, based on index information in the target configuration file, segments indicated by the index information. In some embodiments, the electronic device may download and play the first segment from the server based on the first index information in the target configuration file, and the electronic device may further download and play the second segment from the server based on the second index information.
Step 205: The electronic device caches and plays a first segment, and associates first index information with the cached first segment.
In this embodiment of this application, the electronic device may download the first segment from the server based on the first index information in the received target configuration file, cache the first segment in a local cache apparatus of the electronic device, and associate the first index information with the cached first segment, so that the electronic device can retrieve the first segment based on the first index information, and can read the first segment at any time.
In this embodiment of this application, the electronic device may include a cache apparatus. The cache apparatus may be a static memory (SRAM), also referred to as a random memory, and stores data (for example, index information or a segment) or an instruction (for example, an instruction for playing a segment or an instruction for reading a segment) rapidly.
In this embodiment of this application, after receiving the first segment, the electronic device may cache the first segment in the electronic device.
In this embodiment of this application, after playing the first segment, the electronic device may cache the first segment in the electronic device.
In this embodiment of this application, the electronic device may further cache a text indicating an association between the first segment and the first index information in the cache apparatus.
Step 206: The electronic device plays the cached first segment in a case that second index information is the same as the first index information.
In this embodiment of this application, the electronic device may determine, based on the second index information, whether segments of same content have been cached in the electronic device. If there is index information (the first index information in this embodiment) that is the same as the second index information in the cache apparatus of the electronic device, it indicates that a segment that has the same content as the second segment exists in the electronic device, and the segment (the first segment in this embodiment) is cached in the local cache apparatus, the electronic device directly reads the cached first segment from the cache apparatus and plays the cached first segment based on the first index information that is the same as the second index information.
According to the media file play method provided in this embodiment of this application, after an electronic device sends, to a server, a first request message for playing a target media file, the server may send a target configuration file corresponding to the target media file, where the target media file includes a plurality of segments, and the plurality of segments include a first segment and a second segment; and the target configuration file includes a plurality of pieces of index information, the plurality of pieces of index information include first index information and second index information, and the first index information and the second index information are respectively used to indicate the first segment and the second segment in the target media file, where a play sequence of the first segment is earlier than a play sequence of the second segment. When playing the target media file, the electronic device can play the target media file in segments. When the second segment and the first segment have duplicate content, the electronic device does not download the second segment from the server, but reads the cached first segment from a cache apparatus of the electronic device. Therefore, when there are duplicate segments in the target media file, if duplicate segments have been cached in the electronic device, the electronic device does not need to repeatedly download the duplicate segments from the server, thereby avoiding a waste of traffic when the electronic device plays a media file, and improving efficiency of playing the media file by the electronic device.
In this embodiment of this application, as shown in
Step 207: The electronic device obtains a second segment from the server based on the second index information.
In this embodiment, the electronic device may determine, based on the second index information, whether segments of same content have been cached in the electronic device. If the electronic device determines, based on the second index information, that no segment that has the same index information as the second index information has been cached, the electronic device may download the second segment from the server.
It can be understood that when the electronic device performs retrieval based on the second index information, if no index information that is the same as the second index information is retrieved, it indicates that there is no cached segment that duplicates the second segment in the electronic device. If the electronic device needs to play the second segment, the second segment needs to be downloaded from the server before playing.
Step 208: The electronic device caches and plays the second segment, and associates the second index information with the cached second segment.
In this embodiment of this application, after playing the second segment, the electronic device caches the second segment in the cache apparatus of the electronic device. After the second segment is cached, the electronic device may establish an association between the second index information and the second segment, so that the electronic device can directly read the second segment from the local cache apparatus when playing a segment that is behind the second segment and whose content duplicates that of the second segment, and does not need to download the duplicate segments from the server again.
In this embodiment of this application, after receiving the second segment, the electronic device may cache the second segment in the electronic device.
In this embodiment of this application, after playing the second segment, the electronic device may cache the second segment in the electronic device.
In this embodiment of this application, the electronic device may further cache an association text between the second segment and the second index information in the cache apparatus.
According to the media file play method provided in this embodiment of this application, only when a segment indicated by index information that is the same as the second index information is not cached in the cache apparatus of the electronic device, that is, when no duplicate segment of the second segment is cached in the cache apparatus of the electronic device, the electronic device needs to obtain the second segment from the server, and plays the second segment. Therefore, the electronic device can determine, based on whether the cache apparatus of the electronic device stores a duplicate segment whose content is the same as that of the second segment, whether to download the second segment from the server, so that a waste of traffic caused by downloading the duplicate segments from the server by the electronic device in response to a play request of the user can be avoided.
In this embodiment of this application, with reference to
Step 209: The server identifies the target media file.
In this embodiment of this application, after receiving the target media file uploaded by the media file provider, the server may perform an identification operation on the target media file. In some embodiments, the server identifies whether there are duplicate segments in the target media file. If there are duplicate segments, step 210 is performed.
Step 210: The server divides the target media file into a plurality of segments.
The plurality of segments include the first segment and the second segment.
In this embodiment of this application, the server may divide the target media file into a plurality of segments based on scene content of the target media file.
For example, in a case that the target media file is a video file, if there are duplicate segments in the target media file, for example, when the target media file is a sports tutorial media file, because most scene content is duplicate actions in beats, the server may divide each duplicate action segment into one video segment based on content of the target media file, for example, the first segment and the second segment.
For example, in a case that the target media file is an audio file, if there are duplicate audio segments in the target media file, for example, the target media file is a white noise media file with duplicate audio content, the server may divide each duplicate audio segment into one audio segment based on content of the target media file, for example, the first segment and the second segment.
For example, in a case that the target media file is an audio and video file, if there are synchronously duplicate segments in audio and a video in the target media file, for example, when the target media file is a landscape media file with synchronously duplicate audio and video content, the server may divide each segment with synchronously duplicate audio and video into one audio and video segment based on content of the target media file, for example, the first segment and the second segment.
In some embodiments, the foregoing step 210 may be implemented by the following step 210a.
Step 210a: If duration of the duplicate segment in the target media file is greater than or equal to a preset threshold, the server divides the target media file into the first segment and the second segment.
In this embodiment of this application, the duration of the duplicate segment may be duration required for entirety playing the duplicate segment.
For example, as shown in
It can be understood that when the target media file is an audio file or a video file, a division manner thereof is the same as a division manner when the target media file is an audio and video file. For example, as shown in
For example, as shown in
According to the media file play method provided in this embodiment of this application, the server may perform slice processing on the target media file by identifying duplicate segments in the target media file, to divide the target media file into a plurality of segments, and configure the corresponding first index information and the second index information, and the electronic device does not need to repeatedly download the duplicate segments from the server when playing the duplicate segments, so that the electronic device can save traffic when playing the target media file.
In this embodiment of this application, with reference to
Step 211: If there are synchronously duplicate segments in audio and a video in a media file, the server processes the media file into one target media file.
In this embodiment of this application, the media file may be a media file with synchronously duplicate audio and video. When the audio and the video synchronously duplicate, the server uses the media file as one target media file, that is, the server uses the media file as one target media file, and configures one target configuration file, that is, one M3U8 file, for the target media file.
It should be noted that “synchronously duplicate segments in audio and a video” means that video content of at least two segments in a plurality of segments in the media file is the same, and audio content is also the same. In this embodiment of this application, duration of the foregoing “synchronously duplicate segments in audio and a video” may also be greater than or equal to a preset threshold. When the duration of the duplicate segments is long, it indicates that the server needs to use the media file as the target media file for slice processing. If the duration of the synchronously duplicate segments in the audio and the video is very short, the electronic device consumes less traffic to download the duplicate segments from the server, and the server does not need to use the media file as the target media file for slice processing.
In this embodiment of this application, if duration of the “synchronously duplicate segments in audio and a video” is less than a preset threshold, and the audio or the video in the media file is separately duplicated, the server may split the audio and the video in the media file into two target media files, and then perform slice processing on each target media file.
According to the media file play method provided in this embodiment of this application, in a case that there are synchronously duplicate segments in audio and a video in the media file, the media file is processed into one target media file, so that the electronic device simultaneously plays the audio and the video of the target media file by using one player.
In this embodiment of this application, the media file play method provided in this embodiment of this application may further include the following step 212.
Step 212: The electronic device starts a first player to play a first segment and a second segment of one target media file based on a target configuration file of the target media file.
In this embodiment of this application, the first player may be used to play a video and audio of the target media file (that is, the player may play both the audio of the target media file and the video of the target media file).
In this embodiment of this application, the first segment and the second segment are audio and video segments. The first player may play the first segment and the second segment of the target media file.
It can be understood that, in this embodiment, when the electronic device plays the first segment and the second segment based on the first index information and the second index information by using the first player, if the second index information is the same as the first index information, it indicates that content of the second segment is the same as that of the first segment, the electronic device does not download the second segment from the server, but reads the cached first segment from the cache apparatus of the electronic device, and plays the first segment by using the first player. A method for playing the first segment and the second segment by the electronic device based on the first index information and the second index information in the target configuration file is described in detail in the foregoing embodiment, and details are not described herein again.
According to the media file play method provided in this embodiment of this application, the electronic device plays, by using one player, the first segment and the second segment in the target media file that are indicated by first index information and second index information, to ensure sound and picture synchronization when the target media file is played on the basis of saving player resources, thereby improving play efficiency of the terminal device.
In this embodiment of this application, with reference to
Step 213: If there are duplicate segments in audio or a video in a media file, the server processes the media file into two target media files.
One of the two target media files is an audio file, and the other of the two target media files is a video file.
In this embodiment of this application, the media file may be a media file in which there are duplicate segments in audio or a video. When there are duplicate segments in the audio or the video, the server splits the media file into two target media files, where one is an audio file, that is, an audio target media file, and the other is a video file, that is, a video target media file. The server splits the media file into two target media files, and each target media file includes a first segment and a second segment. The server may also separately configure two target configuration files for the two target media files, that is, the server separately configures two M3U8 files for the two target media files, where each M3U8 file includes first index information and second index information, the first index information in each M3U8 file is used to indicate a first segment in the M3U8 file, and the second index information is used to indicate a second segment in the M3U8 file.
It should be noted that a data frame of the media file may have a type identifier. It may be determined, based on these identifiers, that the data frame is an audio data frame or a video data frame. In this embodiment of this application, the media file may include both an audio data frame and a video data frame. The server may separately extract the audio data frame and the video data frame from the media file. The extracted audio data frame may be generated as one target media file, that is, the foregoing audio target media file. The extracted video data frame may be generated as one target media file, that is, the foregoing video target media file.
In this embodiment of this application, when the server is requested by the electronic device to play the media file, if the server splits the media file into two target media files, the server sends a corresponding identifier to the electronic device, and the electronic device simultaneously sends two first request messages to the server based on the identifier, so that the electronic device can separately play the two target media files by using different players.
In this embodiment of this application, target configuration files of the two target media files may be different configuration files. That is, first index information of the audio target media file and first index information of the video target media file may be different index information, and second index information of the audio target media file and second index information of the video target media file may be different index information.
For example, “there are duplicate segments in audio or a video” means that there are duplicate segments in the audio in the media file, there are duplicate segments in the video in the media file, or there are duplicate segments in the audio and the video in the media file, but duplication of the audio and the video is not synchronized. As shown in
According to the media file play method provided in this embodiment of this application, the server splits the media file into two target media files: an audio target media file and a video target media file, where one or two target media files include duplicate segments, so that slice processing can be separately performed on the two target media files based on an actual situation of the media file, thereby saving traffic of downloading the duplicate segments.
In this embodiment of this application, the media file play method provided in this embodiment of this application may further include the following step 214.
Step 214: The electronic device starts a second player to play a first segment and a second segment in one target media file based on a target configuration file of the one target media file, and the electronic device starts a third player to play a first segment and a second segment in the other target media file based on a target configuration file of the other target media file.
In this embodiment of this application, when a media file is split into two target media files, the electronic device may start two players to separately play the two target media files.
For example, in this embodiment of this application, as shown in
It should be noted that duration and a quantity of segments in the video target media file may be the same as or different from duration and a quantity of segments in the audio target media file.
For example, in this embodiment of this application, as shown in
According to the media file play method provided in this embodiment of this application, two target media files are separately played by the electronic device by using two players. The electronic device may separately read duplicate segments for play from the cache apparatus of the electronic device based on duplicate situations of the audio and the video in the media file, thereby saving traffic of downloading the duplicate segments by the electronic device based on the respective duplicate situations of the audio and the video in the media file.
