The present disclosure generally relates to the field of communications technology, and more particularly, to a method and apparatus for adjusting playing progress of a media file.
Recently, the rapid development of terminal technology makes terminal devices have more and more functions and types. For example, a user may install media player software on a smart phone for playing a media file on the smart phone, and may further adjust a playing progress of the media file according to his/her own needs. The media file may be, e.g., an audio file or a video file.
In related prior art, when adjusting the playing progress of a media file, it may be difficult for a user to adjust the playing progress accurately, resulting in, for example excessive adjustments. In order to solve the above problems, the present disclosure provides a method and apparatus for adjusting playing progress of a media file.

The method includes acquiring a first operation performed by a user with respect to a progress bar of the media file; determining whether the first operation satisfies a preset operation condition; when the first operation satisfies the preset operation condition, determining a progress adjusting rule corresponding to the preset operation condition; and determining a playing progress point of the media file according to the progress adjusting rule and a second operation performed by the user with respect to the progress bar of the media file.
According to a second aspect of the present disclosure, there is provided an apparatus for adjusting playing progress of a media file. The apparatus includes a processor and a memory for storing instructions executable by the processor. The processor is configured to acquire a first operation performed by a user with respect to a progress bar of the media file; determine whether the first operation satisfies a preset operation condition; when the first operation satisfies the preset operation condition, determine a progress adjusting rule corresponding to the preset operation condition; and determine a playing progress point of the media file according to the progress adjusting rule and a second operation performed by the user with respect to the progress bar of the media file.
According to a third aspect of the present disclosure, there is provided a non-transitory computer-readable storage medium having stored thereon instructions that, when executed by a processor in a terminal device, cause the terminal device to perform a method for adjusting a playing progress of a media file. The method includes acquiring a first operation performed by a user with respect to a progress bar of the media file; determining whether the first operation satisfies a preset operation condition; when the first operation satisfies the preset operation condition, determining a progress adjusting rule corresponding to the preset operation condition; and determining a playing progress point of the media file according to the progress adjusting rule and a second operation performed by the user with respect to the progress bar of the media file.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.
Methods for adjusting a playing progress of a media file provided by the present disclosure will be described in detail below. The methods may be applicable to a terminal device. The terminal device may include, but is not limited to, a smart phone, a table computer, and the like.
In step 101, a first operation performed by a user with respect to a progress bar of a media file is acquired.
The media file may be, e.g., a video file or an audio file. The user may perform a variety of operations on a progress bar of the video file or the audio file, such as a quick dragging, a slow dragging, a forward dragging, or a backward dragging.
The progress bar may be a sliding block for adjusting a playing progress of the media file. The sliding block may be located at an arbitrary position on a graphical user interface displayed by a terminal device.
The first operation may be a touch operation, for example, clicking and dragging the progress bar by the user. The first operation may also be a non-touch operation, such as a gesture of dragging the progress bar. When the first operation is a non-touch operation, the terminal device may first recognize whether a gesture of the user is a gesture of dragging the progress bar. If the gesture of the user is a gesture of dragging the progress bar, then the terminal device may further recognize a type of the gesture of dragging the progress bar. For example, the terminal device recognizes whether the gesture of dragging the progress bar is a quick dragging, a slow dragging, a forward dragging, a backward dragging, or the like.
In step 102, it is determined whether the first operation satisfies a preset operation condition.
In the exemplary embodiment, an operation satisfying the preset operation condition may be an operation which can reflect that a target progress point is about to be reached during dragging the progress bar. For example, with respect to a condition in which an excessive adjustment over a target progress point occurs, a user may drag back the progress bar to reach closer to the target progress point. In another example with respect to a condition that a target progress point is about to be reached, a user may slow down dragging the progress bar.
In some embodiments, step 101 may further include determining whether the first operation is an operation in which the progress bar is backward dragged during dragging the progress bar. If the progress bar has been dragged backward, the first operation is determined to satisfy the preset operation condition.
For example, as shown in
In some embodiments, step 101 may further include determining whether the first operation is an operation in which a variation in a dragging speed is greater than a preset value during dragging the progress bar. If so, the first operation is determined to satisfy the preset operation condition. This may be applied to a scenario where the dragging speed changes from a fast speed to a slow speed, or to a scenario where the dragging speed changes from a slow speed to a fast speed.
For example, as shown in
When the user desires to accurately adjust the playing progress of a media file, the user may continuously drag the progress bar for several times. Accordingly, in some embodiments, step 101 may further include determining whether the first operation is an operation in which a number of consecutive draggings of the progress bar within a preset time period is greater than a threshold value. If so, the first operation is determined to satisfy the preset operation condition.
In step 103, when the first operation satisfies the preset operation condition, a progress adjusting rule corresponding to the preset operation condition is determined.
In exemplary embodiments, the terminal device may pre-store a plurality of progress adjusting rules. Each of the progress adjusting rules corresponds to one type of operation condition, so as to ensure that an adjusting amplitude of the media file may be accurately calculated with respect to different types of operation conditions. Accordingly, step 103 may further include selecting a progress adjusting rule corresponding to the preset operation condition from the plurality of progress adjusting rules stored locally in the terminal device.
In step 104, a playing progress point of the media file is determined according to the selected progress adjusting rule and a second operation performed by the user with respect to the progress bar of the media file.
In the exemplary embodiment, the second operation is an operation that the user continues to drag the progress bar after the first operation is completed. From the perspective of the progress bar, the playing progress point is a position to which the sliding block in the progress bar currently slides. From the perspective of the playing of the media file, the playing progress point is a time point at which the media file currently plays. The first and second operations constitute an entire dragging operation of the user. After the entire dragging operation is completed, a playing progress point after the entire dragging operation is calculated according to the selected progress adjusting rule determined in step 103 and a playing progress point before the entire dragging operation.
In addition, after the end of the second operation, the progress adjusting rule may be restored to a default adjusting rule, i.e., when a normal dragging occurs again, the playing progress of the media file is adjusted according to the default adjusting rule.
Therefore, in the exemplary embodiment, a corresponding progress adjusting rule may be selected according to an operation type performed by the user. As such, the playing progress can be accurately adjusted to a playing progress point desired by the user, so that an excessive adjustment can be avoided.
In some embodiments, the above progress adjusting rule may include a proportional relation between a physical dragging distance of the progress bar and a progress adjusting amplitude of the media file. For example, the progress adjusting amplitude of the media file corresponding to a unit physical dragging distance of the progress bar during the first operation is greater than the progress adjusting amplitude of the media file corresponding to a unit physical dragging distance of the progress bar during the second operation.
For example, during the first operation, the progress adjusting amplitude of the media file may have a correspondence to the unit physical dragging distance of the progress bar, such as dragging 1 mm of the progress bar corresponding to skipping 60 seconds of the audio media file; and during the second operation, the progress adjusting amplitude of the media file may have a correspondence to the unit physical dragging distance of the progress bar, such as dragging 1 mm of the progress bar corresponding to skipping 10 seconds of the audio media file.
In one exemplary embodiment, the terminal device plays an audio file (e.g., an Audio.mp3 file), and the user presses and drags a progress bar of the audio file. In a process from starting dragging the progress bar to completing one dragging in which the progress bar is kept being pressed by the user, the audio file skips 60 seconds each time when the progress bar is dragged in the same direction by 1 mm. However, when the user accomplishes the one dragging and then drags the progress bar in an inverse direction or slows down the dragging speed without releasing his/her hand, an audio adjusting amplitude corresponding to dragging a unit physical dragging distance becomes smaller. For example, in this circumstance, each time the progress bar is dragged by 1 mm along the reverse direction, the audio file skips 10 seconds.
In some embodiments, step 104 may further include steps shown in
In step 401, a physical dragging distance of the progress bar corresponding to the second operation is acquired.
For example, during a process from starting dragging the progress bar to completing such one dragging in which the progress bar is kept being pressed by the user, the sliding physical distance of the progress bar is 2 mm, and then the progress bar is dragged in a reverse direction by 1 mm. The physical dragging distance corresponding to the second operation is 1 mm.
In another example, during a process from starting dragging the progress bar to completing such one dragging in which the progress bar is kept pressed by the user, the sliding physical distance of the progress bar is 2 mm, and then the progress bar is dragged slowly in the same direction by 1 mm. The physical dragging distance of the progress bar corresponding to the second operation is 1 mm.
In step 402, a media file adjusting amplitude corresponding to the second operation is calculated according to a proportion between the unit physical dragging distance of the progress bar and the progress adjusting amplitude of the media file recorded in the progress adjusting rule, and the physical dragging distance of the progress bar corresponding to the second operation.
For example, during the second operation, if each time the progress bar is dragged in a direction by 1 mm, the audio file skips 10 seconds accordingly. As such, each time when the user drags slowly the progress bar in the same direction or drags the progress bar reversely by 1 mm, the adjusting amplitude of the audio file is 10 seconds (i.e., 10 seconds/mm*1 mm=10 seconds.)
In step 403, a playing progress point of the media file is determined according to the media file adjusting amplitude corresponding to the second operation and a playing progress point of the media file before the second operation is performed by the user.
For example, a playing progress point of the audio file before the above first operation performed by the user is at 1 minute and 20 seconds. During the first operation, every time the progress bar is dragged in a direction by 1 mm, the audio file skips 60 seconds. During a process from starting dragging the progress bar to completing such one dragging in which the progress bar is kept pressed by the user, a sliding physical distance of the progress bar is 2 mm. Then an adjusting amplitude of the audio file is 120 seconds (i.e., 60 seconds/mm*2 mm=120 seconds). Accordingly, the playing progress point of the above audio file after the above first operation performed by the user is at 3 minutes and 20 seconds (i.e., 1 minute and 20 seconds plus 120 seconds is the 3 minutes and 20 seconds).
At this time, if the progress bar is reversely dragged by 1 mm (i.e., a second operation is performed), the playing progress point of the media file after the second operation is at 3 minutes and 10 seconds (i.e., 3 minutes and 20 seconds−(10 seconds/mm*1 mm)=3 minutes and 10 seconds). Alternatively, if the progress bar is slowly dragged in the same direction by 1 mm, the playing progress point of the media file after the second operation is at 3 minutes and 30 seconds (i.e., 3 minutes and 20 seconds+(10 seconds/mm*1 mm)=3 minutes and 30 seconds).
In the exemplary embodiments, the dragging intention of the user during dragging the progress bar can be recognized. Based on the dragging intention of the user, the media file adjusting amplitude corresponding to the physical dragging distance is adaptively adjusted. In this way, the progress can be accurately adjusted to a desired progress point, so that an excessive adjustment can be avoided.
For making the progress adjustment more accurate, in some embodiments, the method 100 (
When the above first operation satisfies the preset operation condition, the progress bar of the media file within a first progress range is enlarged and shown according to a preset presenting parameter, wherein a termination position of the first operation is located within the first progress range.
It can be appreciated that during dragging the progress bar by the user, when the progress bar is dragged near to the target progress point or the progress bar is slightly over-adjusted with respect to the target progress point, the user generally pauses the dragging operation, and then slows down the dragging of the progress bar or reversely drags the progress bar. In addition, enlarging and presenting the progress bar of the media file also facilitates the user to accurately adjust the progress bar. For this, a portion of the progress bar near the pausing position may be enlarged and shown.
It should be noted, the first progress range in the present exemplary embodiment may be, but is not limited to, 10 mm.
For example, when the first progress range is 10 mm, a progress bar within the 10 mm range to the left of the termination position of the first operation may be enlarged and presented; or a progress bar within the 10 mm range to the right of the termination position of the first operation may be enlarged and presented. Alternatively, a progress bar within a X mm range to the right of the termination position of the first operation may be enlarged and presented and a progress bar within a Y mm range to the left of the termination position of the first operation may be enlarged and presented, wherein X+Y=10 mm.
In the exemplary embodiments, the presenting parameter of the progress bar of the media file may be automatically adjusted according to the gesture operation intention of the user, such that the progress bar is adjusted to a size suitable for the user's operation and then is presented. In this way, it is convenient for the user to quickly and accurately adjust the playing progress of the media file.
Considering the diversity of the dragging operations and the requirements of the user for setting the progress adjusting rule according to his/her own needs, the present disclosure may provide the user with an interface for setting the progress adjusting rule. Accordingly, in some embodiments, the method 100 (
In another embodiment, the method 100 (
In the exemplary embodiments, an interface for setting the progress adjusting rule may be provided to the user. In this way, the requirement of the user for customizing the progress adjusting rule may be satisfied, and on the other hand, a calculation rule which matches the dragging operation may be provided, thereby improving the accuracy of the adjusting result.
It should be noted, although the operations of the methods of the present disclosure are described in a specific order in the drawings, it is not required or does not imply that these operations must be performed in the specific order, or the desired result can be only achieved by performing all the illustrated operations. The executing sequence of the steps depicted in the flow charts may be changed. Additionally or alternatively, some steps may be omitted, several steps may be combined into one step to be performed, and/or one step may be divided into multiple steps to be performed.
