Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
An embodiment of the present invention provides a video playing method, which may be applied to an electronic device, where the electronic device is used to play a video, and the electronic device may be an intelligent device such as a mobile phone and a tablet computer, and referring to fig. 1, the method may include the following steps:
s101: in the process of playing the first video, when a preset synchronous playing condition is met, the current playing progress of the first video is obtained and used as the first playing progress.
S102: and determining the playing progress synchronous with the first playing progress in a second video to be synchronously played with the first video as a second playing progress.
Wherein the first video and the second video are: and shooting a plurality of videos obtained by shooting the same shooting object by adopting different shooting visual angles.
S103: and starting to play the second video from the second playing progress.
Therefore, the video playing method provided by the embodiment of the invention can realize synchronous playing of a plurality of videos obtained by shooting the same shooting object at different shooting visual angles, and provides better visual experience for a user to simultaneously present video pictures of the same shooting object at the different shooting visual angles.
In step S101, the preset synchronization playing condition may indicate that another video (i.e., the second video in the embodiment of the present invention) to be synchronized with the first video needs to be played currently.
It should be noted that the first video and the second video may be: and shooting a plurality of videos obtained by shooting the same shooting object by adopting different shooting visual angles.
In different shooting scenes, the shooting subjects may be different.
For example, for a shooting scene of a stage performance, the shooting subjects of the first video and the second video may be a performance stage, and then the shooting perspective of the first video may be a panorama of the performance stage, and the shooting perspective of the second video may be a close-up of an actor in the performance stage.
Alternatively, the shooting subjects of the first video and the second video may be actors a in the performance stage, the shooting perspective of the first video may be full-body pictures of the actors a, and the shooting perspective of the second video may be close-ups of the faces of the actors a.
For another example, for a shooting scene of video teaching, the shooting objects of the first video and the second video may be a platform, the shooting angle of the first video may be a panorama of the platform, and the shooting angle of the second video may be a close-up of a teacher in the platform.
It should be noted that the time lengths of the first video and the second video may be the same or different.
For example, if the first video is a video of a 1-hour stage show and the video frame of the first video is a panorama of the entire performance stage in which actor a appears for 1 hour, the second video may be a video of a 1-hour stage show and the video frame of the second video is a close-up of actor a.
Alternatively, the first video is a 1 hour video of a stage show and the video frame of the first video is a panorama of the entire performance stage in which actor B appears for 20 minutes, the second video may be a 20 minute video of the stage show and the video frame of the second video is a close-up of actor B.
The playing progress of the video may be represented by a currently played time length of the video, for example, if the time length of the first video is 1 hour and the video is currently played for 20 minutes, the first playing progress may represent the 20 th minute.
In one embodiment, the preset synchronized playing condition may include at least one of the following:
receiving a video synchronous playing instruction; the video synchronous playing instruction is used for indicating that a first video and a second video are played synchronously;
detecting the playing progress corresponding to the first video playing to the second video;
detecting a first video fast forward playing;
and detecting the fast-backward playing of the first video.
In the embodiment of the present invention, the electronic device may be provided with two different play modes, including: a synchronized play mode and an unsynchronized play mode. The user can select different playing modes through the electronic equipment to play the video.
For example, a "mode switching" button may be provided in an interface of the electronic device, and when the user clicks the button, the electronic device may switch the play mode.
Or, when the user horizontally puts the electronic device, the electronic device may automatically switch to the synchronous play mode, and when the user vertically puts the electronic device, the electronic device may automatically switch to the asynchronous play mode.
Accordingly, the video synchronous playing instruction may be triggered by the user clicking a "mode switching" button, or may be triggered by the user when the electronic device is laid horizontally.
In another mode, when the first video is played to the playing progress corresponding to the second video, the preset synchronous playing condition is also met, and at this time, the first video and the second video can be synchronously played.
For example, the first video is a video of a 1-hour stage show, and the video frames of the first video are panoramas of the entire performance stage in which actor B appears for 20 minutes, the second video may be a video of a 20-minute stage show, and the video frames of the second video are close-ups of actor B, which appears at times corresponding to 20-40 minutes of the first video, that is, actor B appears at 20-40 minutes of the first video.
Correspondingly, when the first video is played to the playing progress (namely, 20 th minute) corresponding to the second video, it is determined that the preset synchronous playing condition is met, and the first video and the second video can be synchronously played.
In another mode, in the process of playing the first video, if the user selects to fast forward or fast rewind to play the first video, the user may fast forward to the playing progress corresponding to the second video, or fast rewind to the playing progress corresponding to the second video, so that it may be determined that the preset synchronous playing condition is met.
With respect to step S102, in one embodiment, if the duration of the second video is the same as the duration of the first video, the first playing progress may be directly determined as the second playing progress.
In one embodiment, referring to fig. 2, S102 may include:
s1021: in the first video, a target video segment corresponding to the second video is determined.
S1022: and calculating the difference between the first playing progress and the corresponding playing progress of the starting time of the target video segment in the first video to be used as a second playing progress.
The target video segment in the first video corresponding to the second video represents a video segment in the first video that needs to be played synchronously with the second video, and it can be understood that if the duration of the second video is the same as that of the first video, the target video segment in the first video corresponding to the second video represents the whole first video. The duration of the target video segment is the same as the duration of the second video.
For example, if the first video is a video of a 1-hour stage show and the video frame of the first video is a panorama of the entire performance stage in which actor a appears for 1 hour, the second video may be a video of a 1-hour stage show and the video frame of the second video is a close-up of actor a. At this time, the target video segment is the first video, and the start time of the target video segment is the start time of the first video. The corresponding playing progress of the starting time of the target video segment in the first video is 0 minute.
When the preset synchronous playing condition is determined to be met, if the current first video is played to the 30 th minute, namely the first playing progress is the 30 th minute. The difference between the first playing progress and the corresponding playing progress of the starting time of the target video segment in the first video is 30 minutes, and further, the second playing progress can be determined to be 30 minutes, and the second video can be played from 30 minutes.
As another example, the first video is a 1-hour video of a stage performance, and the video frames of the first video are panoramas of the entire performance stage in which actor B appears for 20 minutes, the second video may be a 20-minute video of the stage performance, and the video frames of the second video are close-ups of actor B, which appears at times corresponding to 20-40 minutes of the first video, that is, actor B appears at 20-40 minutes of the first video. At this time, the target video segment corresponding to the second video is the video segment from the 20 th minute to the 40 th minute in the first video, and the starting time of the target video segment is the 20 th minute, and the playing progress of the starting time of the target video segment in the first video is the 20 th minute.
When the preset synchronous playing condition is determined to be met, if the current first video is played to the 30 th minute, namely the first playing progress is the 30 th minute. The difference between the first playing progress and the corresponding playing progress of the starting time of the target video segment in the first video is 10 minutes, and further, the second playing progress can be determined to be 10 minutes, and the second video can be played from 10 minutes.
In one embodiment, to further improve the playing effect of the synchronized playing of the first video and the second video, the method may further include the following steps:
in the process of simultaneously playing the first video and the second video, when the first video is detected to be paused, pausing the playing of the second video; and/or resuming playing the second video when resuming playing of the first video is detected.
Wherein resuming the playback means switching from the paused playback to the normal playback.
In the embodiment of the present invention, since the second video needs to be played synchronously with the first video, when the user selects to pause playing the first video, the electronic device may pause playing the second video, and when the user selects to resume playing the first video, the electronic device may resume playing the second video, so as to keep playing the second video and the first video synchronously.
In an embodiment, in order to further improve the playing effect of the synchronized playing of the first video and the second video, on the basis of fig. 1, referring to fig. 3, the method may further include the following steps:
s104: in the process of simultaneously playing the first video and the second video, when a preset adjustment playing condition is met, the current playing progress of the first video is obtained and used as a third playing progress, and the current playing progress of the second video is used as a fourth playing progress.
S105: judging whether the first video and the second video meet the preset synchronous playing requirement or not based on the third playing progress and the fourth playing progress; if not, determining the playing progress synchronous with the third playing progress in the second video as a fifth playing progress; and starting to play the second video from the fifth playing progress.
If the preset synchronous playing requirement is not met, the synchronous playing effect between the second video and the first video is poor, and the playing progress of the second video needs to be adjusted.
In the embodiment of the invention, in the process of synchronously playing the first video and the second video, the influence of a network and the operation of a user can cause that the second video and the first video cannot achieve a better synchronous playing effect, and at the moment, the playing progress of the second video can be adjusted, so that the second video and the first video can achieve a better synchronous playing effect.
In one implementation, it may be determined whether a difference between the third playing progress and the fourth playing progress falls within a preset range, and if not, it indicates that the preset synchronous playing requirement is not satisfied, and the synchronous playing effect between the second video and the first video is poor, so that the playing progress of the second video needs to be adjusted. The preset range can be determined according to the playing progress corresponding to the playing from the first video to the second video.
For example, the first video is a video of a 1-hour stage show, and the video frames of the first video are panoramas of the entire performance stage in which actor B appears for 20 minutes, the second video may be a video of a 20-minute stage show, and the video frames of the second video are close-ups of actor B, which appears at times corresponding to 20-40 minutes of the first video, that is, actor B appears at 20-40 minutes of the first video.
If the playing progress from the playing of the first video to the playing of the second video is 20 minutes, the preset range may be 19 minutes, 57 seconds to 20 minutes, 3 seconds, and the third playing progress is 32 minutes, 30 seconds.
If the current fourth playing progress is 12 minutes and 35 seconds, the difference value between the third playing progress and the fourth playing progress is 19 minutes and 55 seconds, and the current fourth playing progress does not belong to the preset range, and the preset synchronous playing requirement is determined not to be met; if the current fourth playing progress is 12 minutes and 25 seconds, the difference value between the third playing progress and the fourth playing progress is 20 minutes and 5 seconds, and the current fourth playing progress does not belong to the preset range, determining that the preset synchronous playing requirement is not met; and if the current fourth playing progress is 12 minutes and 28 seconds, the difference value between the third playing progress and the fourth playing progress is 20 minutes and 2 seconds, and the current fourth playing progress belongs to the preset range, and the preset synchronous playing requirement is determined to be met.
The method for determining a fifth playing progress synchronized with the third playing progress in the second video and starting to play the second video from the fifth playing progress may refer to the detailed description of determining a second playing progress synchronized with the first playing progress and starting to play the second video from the second playing progress in the foregoing embodiments.
In addition, if the first video and the second video currently meet the preset synchronous playing requirement, the playing progress of the second video may not be adjusted.
In one embodiment, the preset adjustment playing condition may include at least one of the following:
detecting that the first video is recovered to a normal playing state from a pause playing state;
detecting that the second video is recovered to a normal playing state from the pause playing state;
and detecting that the second video resumes playing.
In the embodiment of the present invention, due to a network reason, a pause may occur when the first video is played, and after the first video is restored from the pause playing state to the normal playing state, the second video may be out of synchronization with the first video.
In addition, a pause may occur during playing the second video, and after the second video is restored from the pause playing state to the normal playing state, the second video may be out of synchronization with the first video.
In addition, when the first video resumes playing, the second video may resume playing synchronously, however, due to the different time consumption for loading the video, when the second video resumes playing, the second video may be out of synchronization with the first video.
Therefore, when any one of the above conditions is detected, it can be determined that the preset adjustment playing condition is met, and then, it can be determined whether the first video and the second video currently meet the preset synchronous playing requirement, so as to perform corresponding processing.
In an embodiment, in order to increase the loading speed of the second video and further increase the effect of playing the second video in synchronization with the first video, referring to fig. 4, before S103, the method may further include the following steps:
s106: and the video data of the second video is preloaded from the server and cached.
Accordingly, step S103 may include the steps of:
s1031: and playing the second video based on the target video data in the video data of the cached second video.
Wherein the target video data includes: and the video data corresponds to the second playing progress and the video data which is positioned behind the second playing progress and corresponds to the playing progress.
In the embodiment of the present invention, before playing the second video, the electronic device may load the video data of the second video from the server in advance and cache the video data.
In one implementation, the electronic device may cache the video data of the second video locally, or the electronic device may also cache the video data of the second video in a storage device located in the same local area network as the electronic device, where the storage device may be a server.
