Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Before explaining the embodiments of the present application in detail, an application scenario of the embodiments of the present application will be described.

The method and the device for playing the video are applied to scenes that a user drags the progress bar to fast forward or fast backward in the video playing process. In the related art, after a user drags a progress bar, a terminal decodes and loses frames all the time, and the terminal can start playing from a dragged time point after decoding for a period of time, so that the user can see a played video after waiting for a long time after dragging the progress bar, and the user experience is poor. According to the embodiment of the application, in order to respond to the dragging operation of the user in time after the user drags the progress bar, the user is prevented from waiting for a long time, and the following video playing method is provided.

Fig. 1 is a flowchart of a video playing method provided in an embodiment of the present application, where the method is used in a terminal, and the terminal may be a mobile phone, a tablet computer, a computer, or the like. Illustratively, the method is applied to a video playing application installed on a terminal. Referring to fig. 1, the method includes:

step 101: when a progress bar dragging instruction of a video is received, a first time point to which the progress bar is dragged is determined.

In some examples, the progress bar dragging instruction of the video may be received when the video starts to be played, or the progress bar dragging instruction of the video may be received in the video playing process, or the progress bar dragging instruction of the video may be received when the video pauses to be played, which is not limited in the embodiment of the present application.

The progress bar dragging instruction is used for adjusting the display progress of the progress bar, and then the playing progress of the video is adjusted. The progress bar dragging instruction may include a forward progress bar dragging instruction for fast forwarding the video, or a backward progress bar dragging instruction for fast rewinding the video. The progress bar dragging instruction can be triggered by a user through progress bar dragging operation, the progress bar dragging operation can be clicking operation on a certain position in the progress bar, dragging operation on a progress bar upper degree slider and the like. In some examples, the received progress bar drag instruction may be referred to as a Seek event.

The first time point is a playing time point to which the progress bar is dragged, and is used for indicating the display progress of the dragged progress bar. The first time point may be before the current playing time point or after the current playing time, which is not limited in this embodiment of the application.

Step 102: the key frame closest to the first time point is determined from the video frames of the video.

That is, the key frame closest to the first time point may be determined from a plurality of key frames of the video.

Video is typically composed of a plurality of video frames, each representing an image. The video frames of the video comprise key frames and non-key frames, the key frames are important auxiliary information of the video, the fast browsing and fast positioning of the video content can be carried out through the key frames, and the key frames can be independently decoded. Therefore, when the progress bar dragging instruction is received, the key frame closest to the first time point needs to be determined first, so that the video playing is performed based on the closest key frame.

As an example, the key frame closest to the first point in time may be determined from video frames of the video prior to the first point in time. That is, the keyframe closest to the first point in time is the keyframe that precedes and is closest to the first point in time.

As another example, a key frame closest to a first point in time may be determined from video frames of the video subsequent to the first point in time. That is, the keyframe closest to the first point in time is the keyframe that is after and closest to the first point in time.

Step 103: and starting to play the video from a second time point corresponding to the key frame.

It should be noted that, in the related art, when the progress bar is dragged to the first time point, the video is played from the first time point in one pass, but if the video is played from the first time point, decoding and frame dropping need to be started from the key frame closest to the first time point until the video frame corresponding to the first time point is decoded, and the user waiting time is long.

In order to save the waiting time of the user, the embodiment of the application provides a method for starting playing from the second time point corresponding to the key frame closest to the first time point, that is, after the key frame closest to the first time point is determined, decoding and playing can be directly started from the key frame, so that the problem that the playing is started after some video frames are decoded and discarded in the related technology is avoided, the waiting time of the user is too long, the user can see the played video without waiting after dragging the progress bar, and the user experience is improved.

As an example, after determining a key frame closest to the first time point, a video frame of the video may be decoded from the key frame, and the decoded video frame may be played such that the video is played from the second time point.

Step 104: and loading the display progress of the progress bar from the first time point based on the first time point and the second time point and according to a loading speed smaller than the playing speed of the video while playing the video from the second time point corresponding to the key frame until the display progress of the progress bar is the same as the playing progress of the video.

The display progress of the progress bar may be slowly loaded from the first time point while the video is played from the second time point, and a loading speed of the display progress of the progress bar is less than a playing speed of the video. Because the video is played from the second time point according to the normal playing speed, and the progress bar is slowly loaded from the first time point, the playing progress of the video can gradually catch up with the display progress of the progress bar, and finally the display progress of the video is consistent with the display progress of the progress bar.

It should be noted that, in the embodiment of the present application, after the playing progress of the video is adjusted according to the progress bar dragging instruction, the video is played from the second time point, and the progress bar is loaded from the first time point, that is, the playing progress of the video is inconsistent with the display progress of the progress bar, and the video and the progress bar have a certain time difference, but the time difference is usually very small, and is basically not perceived by the user. Moreover, after the progress bar is slowly loaded for a period of time, the terminal can slowly restore the difference between the playing progress of the video and the display progress of the progress bar until the two progress bars are consistent, so that for the user, the most direct feeling is that after the user drags the progress bar, the terminal can respond to the dragging operation of the user at the first time, and the user does not need to wait to play from the dragged time point.

For example, suppose the video has 4 key frames, and the time points of the key frames are distributed as follows: key frame 1, 0 seconds; key frame 2, a seconds; key frame 3, B seconds; key frame 4 for C seconds. When the user drags the progress bar, assuming that the progress bar is dragged to the position of X seconds, the processing procedure of the terminal includes: 1, find the nearest key frame to X seconds, say A seconds, and A seconds is earlier than X seconds. And 2, decoding and playing from A seconds. 3, the actual playing progress of the video is A seconds at this moment, in order to achieve the dragging effect of the user, the display progress of the progress bar can be increased from X seconds, then the progress bar is slowly increased according to a slow loading mode, and thus, the playing progress of the video gradually catches up with the display progress of the progress bar, and finally the display progress of the video is consistent with the display progress of the progress bar.

As an example, the terminal may load the display progress of the progress bar from the first time point according to the following formula (1) based on the first time point and the second time point:

Z＝X+(Y-A)/S (1)

wherein, Z is the display progress of the progress bar, X is the first time point, Y is the playing progress of the video, A is the second time point, S is the preset parameter and S is a positive integer.

As an example, S may be 2, 3, or 4, and the like, which is not limited in this application. When S is 2, as can be seen from the above formula, when the playing progress Y of the video is 2X-a, the display progress of the progress bar may be consistent with the playing progress of the video.

For example, please refer to fig. 2, fig. 2 is a schematic diagram illustrating a relationship between a playing progress of a video and a display progress of a progress bar according to an embodiment of the present disclosure, as shown in fig. 2, after a user drags the progress bar, the playing progress of the video can catch up with the display progress of the progress bar slowly, and after a certain time, the playing progress of the video and the display progress of the progress bar can be consistent.

Furthermore, after the display progress of the progress bar is slowly loaded from the first time point according to the loading speed which is less than the playing speed of the video, when the playing progress of the video is the same as the display progress of the progress bar, the display progress of the progress bar can be continuously loaded according to the playing progress of the video. And when the display progress of the progress bar is continuously loaded according to the playing progress of the video, the loading speed is equal to the playing speed of the video.

For convenience of description, in the embodiment of the present application, a mode in which loading is performed at a loading speed that is less than a playback speed of a video may be referred to as a slow loading mode, and a mode in which loading is performed at a playback progress of a video may be referred to as a normal loading mode. That is, after the progress bar is loaded for a period of time according to the slow loading mode, the playing progress of the video can catch up with the display progress of the progress bar, so that the progress bar and the video are consistent, and when the progress bar and the video are consistent, the slow loading mode of the progress bar can be switched to the normal loading mode, so that the progress bar is loaded according to the normal loading mode.

In the embodiment of the application, when a progress bar dragging instruction of a video is received, a first time point to which the progress bar is dragged can be determined firstly, then a key frame closest to the first time point is determined, and the video is played directly from a second time point corresponding to the key frame, so that the situation that decoding and frame loss need to be carried out from the key frame closest to the first time point is avoided, playing can be started after some video frames are discarded, the problem of overlong waiting time of a user is caused, and after the user drags the progress bar, the dragging operation of the user can be responded in time. Moreover, when the video is played from the second time point, the display progress of the progress bar can be slowly loaded from the first time point based on the first time point and the second time point according to the loading speed less than the video playing speed until the display progress of the progress bar is the same as the video playing progress, so that for a user, the user can still perceive that the video is played from the first time point dragged by the user, and the waiting time of the user is saved while the dragging effect is achieved. In addition, when the video is played from a second time point which is earlier than the dragging time point, the display progress of the progress bar is slowly loaded from the dragging time point, so that the simultaneous response of video playing and progress bar loading can be ensured, the video watching experience of a user is improved, and the defect that the user may feel that the player has a problem if the video starts playing but the progress bar is still motionless under the condition is avoided.

In the embodiment of the application, when a progress bar dragging instruction of a video is received, a first time point to which the progress bar is dragged can be determined firstly, then a key frame closest to the first time point is determined, and the video is played directly from a second time point corresponding to the key frame, so that the situation that decoding and frame loss need to be carried out from the key frame closest to the first time point is avoided, playing can be started after some video frames are discarded, the problem of overlong waiting time of a user is caused, and after the user drags the progress bar, the dragging operation of the user can be responded in time. And, when starting playing the video from the second time point, can also be based on first time point and second time point, according to the loading speed that is less than video playback speed, begin to load the display progress of progress bar slowly from the first time point, until the display progress of progress bar is the same with the broadcast progress of video, thus, can guarantee video broadcast and the response of progress bar loading simultaneously, and, to the user, the user still can perceive that the video is played from the first time point that the user drags, thereby when having reached and dragging the effect, the waiting time of user has been saved, user's video watching experience has been improved.
