Description

Video playing method and device, electronic equipment and storage medium
Technical Field
The present application relates to the field of video playing technologies, and in particular, to a video playing method and apparatus, an electronic device, and a storage medium.
Background
As users tend to be fragmented over time, the most exciting content is viewed for a limited period of time without losing the continuity of the scenario, which is a strong demand for current users. Therefore, how to reasonably shorten the long video to meet the strong demand of the user also becomes a strategic problem to be considered by the long video product.
The existing video shortening is mainly divided into three types. The first is to play the video faster, i.e. at a certain playing speed. The second is to skip directly over other unimportant content, playing only highlights or character segments. The third is to clip the long video into independent short video for direct playing.
However, with the first approach, although the continuity of the matrix is ensured, it takes a long time to play the entire video even at the maximum double speed. For the second, although the duration of a long video can be effectively shortened, the continuity of a scenario is lost. For the video to be edited into the independent short video, although the duration of the video is effectively shortened, the continuity of the scenario can be ensured to a certain extent. However, when the user is interested in the video and needs to watch the original video scenario, the user needs to quit the playing interface to search for the original complete video for playing.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In this application, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in the process, method, article, or apparatus that comprises the element.
An embodiment of the present application provides a video playing method, as shown in fig. 1, including the following steps:
s101, when the target video is requested to be played, acquiring complete audio and video data of the target video and short-cast data of the target video.
The complete audio and video data comprises synchronous complete video data and complete audio data.
The short broadcast data comprises short broadcast audio data, dotting data and audio and video synchronization data. Since the short broadcast data needs to be preset accurately, in the embodiment of the present application, the target video refers to any video in which the corresponding short broadcast data exists.
Alternatively, the on-air audio data may be post-recorded audio, such as a post-recorded explanation of a main scenario of the target video, or the like, or may of course consist of audio that is clipped from the complete audio data. And, the broadcast audio data can be a complete audio data, which is convenient for use and management. However, at this time, in order to make the played audio correspond to the played video clip, it is necessary to logically divide the broadcast audio data into a plurality of broadcast audio clips. For example, a short broadcast audio data of 10 minutes may be divided into short broadcast audio segments every one minute, specifically according to the corresponding relationship with the video segments. Of course, the broadcast audio data may include a plurality of independent broadcast audio data, each of which corresponds to one of the video segments, for example, each of the video segments corresponds to the corresponding explanation audio, so that the broadcast audio data does not need to be logically divided.
The dotting data includes data indicating respective video segments divided in the complete video data. That is, in the embodiment of the present application, by dotting on the complete video, each video segment in the complete video is marked, and the complete video data is not clipped into a plurality of independent video segments. In general, the dotting data is recorded as the corresponding timestamp range of each video clip in the complete video data.
It should be noted that, in order to effectively shorten the long video, the video segments in the complete video data indicated by the dotting data generally include only highlights, character segments and segments playing an important role in the continuity of the scenario, so that the sum of all the divided video segments is not equal to the complete video data, but is only a part of the complete video data.
The audio and video synchronization data comprises the corresponding relation between the short broadcast audio clip in the short broadcast audio data and the video clip in the complete video data.
Specifically, when a user needs to play a target video, a client requests a server for a playing address of the target video. At this time, the server side issues complete audio and video data of the target video and short broadcast data of the target video. Optionally, the complete audio and video data of the target video and the corresponding address of the short broadcast data of the target video are issued, and when the complete audio and video data are used, loading is performed according to the address.
And S102, playing the complete audio and video data of the target video.
In the embodiment of the application, the complete video data of the target video is played by default, so after the complete audio and video data of the target video and the short-cast data of the target video are obtained, the complete video data and the complete audio data are rendered by default and are played synchronously.
Optionally, if the user has not played the complete video-audio-video data of the target video previously, or has played the complete video-audio-video data of the target video completely, then the complete video-audio-video data of the target video is played from the beginning. If the user has previously played the complete video of the target video and has not played the complete video of the target video, the last playing progress of the user can be read, and then the last playing progress of the user continues to play.
And S103, when a short play mode switching instruction is received, pausing to play the complete audio and video data of the target video.
Specifically, when the user operates and switches the short broadcast mode on the client, a short broadcast mode switching instruction is triggered, and at this time, the short broadcast mode needs to be entered. So that the playing of the complete audio-video data of the target video needs to be paused at this time. It should be noted that, since the video segment in the complete video data is still played in the short play mode, the complete audio data is rather paused.
It should be noted that after switching to the short broadcast mode, the user can exit the short broadcast mode at any time, that is, switch back to the conventional mode, and at this time, resume playing the complete audio and video data of the target video.
Optionally, when the complete audio and video data of the target video is resumed, the playing can be continued according to the progress of the complete audio and video data during the pause. Of course, the progress of the played video clip can be continued to be played when switching back to the normal mode.
And S104, determining the current to-be-played short broadcast audio clip and the corresponding current to-be-played video clip from each short broadcast audio clip and each video clip to be played in sequence based on the dotting data and the audio and video synchronization data.
It should be noted that, in the embodiment of the present application, the short broadcast audio clip refers to a short broadcast audio clip in the short broadcast audio data of the target video. The video clips refer to the video clips divided by the dotting data indication in the complete video data of the target video.
The short playing audio clip to be played may be a short playing audio clip that has not been played after the target video is requested this time. Of course, considering that the user may have previously played the target video and may have played a portion of the short play audio clip through the short play mode at that time, the short play audio clip to be played may also refer to the short play audio clip that has not been played since the target video was started to be played. Similarly, the video segment to be played may be a short-play audio that has not been played after the target video is requested, specifically, the video segment may be played in both the normal mode and the short-play mode, or may be simply played in the short-play mode, so that the user is prevented from watching repeatedly, and the configuration is specifically performed according to the requirement.
Alternatively, the broadcast audio stream may be loaded first. Since the dotting data and the audio and video synchronous data can be classified into the short broadcast synchronous script data, the short broadcast synchronous script data can be loaded, and then the short broadcast synchronous script data is analyzed to obtain the dotting data and the audio and video synchronous data.
Since each video clip is not continuous in the complete video, it needs to be played in sequence, and in order to ensure the continuity of the scenario, it needs to play each video clip to be played and each short broadcast audio clip to be played in sequence.
It should be noted that, if the short broadcast audio data is a complete audio, each short broadcast audio clip can be played in sequence only by being played all the time. If the short broadcast audio data is composed of a plurality of independent short broadcast audio clips, the playing sequence may be preset for each short broadcast audio clip. For video clips, the order of the video clips can be determined according to the positions of the video clips in the complete video data or corresponding timestamps.
Optionally, in another embodiment of the present application, a specific implementation manner of step S104, as shown in fig. 2, includes:
s201, determining the currently played short broadcast audio clip as the currently to-be-played short broadcast audio clip.
Wherein, each short broadcast audio clip in the short broadcast audio data is played in sequence.
Since the podcast audio segments are played continuously in sequence, and the video segments are not continuous in the complete video data, when one podcast audio segment is played, the next one is played naturally, and it is required to determine the corresponding video segment based on the next to-be-played podcast audio segment. Therefore, in the embodiment of the present application, the current to-be-played short broadcast audio clip is determined first, and then the current to-be-played video clip corresponding to the current to-be-played short broadcast audio clip is determined.
It should be noted that, in the embodiment of the present application, when switching to the short broadcast mode for the first time after requesting to play the target video, the short broadcast audio data is continuously played from the starting position until the short broadcast is finished or the normal mode is switched back. For example, if the short broadcast audio data is a complete audio data, the short broadcast audio data is played from the 0 th minute, and then the short broadcast audio data is played to each short broadcast audio clip in sequence, and if the short broadcast audio clips are multiple independent short broadcast audio clips, the short broadcast audio clips are also played in sequence uninterruptedly, so that each time one short broadcast audio clip is played, one short broadcast audio clip is immediately followed, and at this time, the played short broadcast audio clip is determined as the short broadcast audio clip to be currently played, so as to match the corresponding video clip for playing.
Optionally, when the user switches back to the normal mode, the currently played short broadcast audio clip may be recorded, and the short broadcast audio clip is set to be played, so that when the user switches to the short broadcast mode again, the short broadcast audio clip is played next. And the progress of playing the short broadcast audio clip can be recorded, so that the short broadcast audio clip can be continuously played based on the playing progress, and at the moment, the progress of the corresponding video clip is required to be synchronously adjusted according to the progress, so that the user is prevented from watching repeated contents.
Of course, since the duration of the short broadcast audio data is relatively short, and the user can also manually adjust the progress, the short broadcast audio clip may be played from the beginning when switching to the short broadcast mode again, or the short broadcast audio data may be played from the beginning, that is, when switching back to the normal mode, the states of all the short broadcast audio clips are set to be played, so that the complexity of the processing logic may be reduced to some extent.
S202, based on the audio and video synchronization data, determining a timestamp range corresponding to a timestamp of the current to-be-played short broadcast audio clip from the dotting data.
S203, determining the video clip in the complete video data corresponding to the searched timestamp range as the current video clip to be played corresponding to the current video clip to be played.
Optionally, in another embodiment of the present application, a specific implementation manner of step S104, as shown in fig. 3, includes:
s301, judging whether the short-cast audio is played for the first time after the short-cast mode switching instruction is received at present.
It should be noted that, in order to avoid playing back the content viewed in the normal mode to the user, in the embodiment of the present application, when playing back in the short play mode, the viewing progress in the normal mode needs to be considered. Therefore, it is required to first determine whether to just switch from the normal mode to the short broadcast mode, that is, determine whether to play the short broadcast audio for the first time after receiving the short broadcast mode switching instruction, and if it is determined that to play the short broadcast audio for the first time after receiving the short broadcast mode switching instruction, it is required to first determine the video segment to be played based on the playing progress, so that step S302 is executed at this time. If it is determined that the short cast audio is not played for the first time after the short cast mode switching instruction is received at present, that is, after the previous video clip and audio clip are played, the next video clip and audio clip are determined, at this time, the determination of the playing sequence of the audio clip may be directly installed, so that step S305 is executed at this time.
S302, finding out the timestamp range closest to the timestamp corresponding to the current playing progress of the complete video data in the dotting data.
Alternatively, when a timestamp is within a range of timestamps, then the timestamp is closest to the range of timestamps, and the time interval between the two may be considered to be zero. And when the time stamp is not in the time stamp range, the time stamp range closest to the time stamp corresponding to the current playing progress may be determined based on the time interval between the time stamp and the lower limit value of the time stamp range.
And S303, determining the video clip in the complete video data corresponding to the searched timestamp range as the current video clip to be played.
S304, based on the audio and video synchronous data, determining the short broadcast audio clip corresponding to the current video clip to be played in the short broadcast audio data as the current short broadcast audio clip to be played.
S305, determining the currently played short broadcast audio clip as the currently to-be-played short broadcast audio clip.
It should be noted that, for the specific implementation of step S305 to step S307, the implementation of step S201 to step S203 may be referred to accordingly, and details are not described here.
And S306, based on the audio and video synchronous data, determining a time stamp range corresponding to the time stamp of the current to-be-played short broadcast audio clip from the dotting data.
S307, determining the video clip in the complete video data corresponding to the searched timestamp range as the current video clip to be played corresponding to the current short broadcast audio clip to be played.
S105, synchronously playing the current to-be-played short broadcast audio clip and the corresponding current to-be-played video clip.
Since the short broadcast audio clip is independent of the video data of the target video, in order to ensure that the content of the audio is consistent with the playing picture, the current short broadcast audio clip to be played and the corresponding current video clip to be played need to be played synchronously.
Specifically, as shown in fig. 4, a specific implementation method of step S105 includes:
s401, calculating the time stamp offset of the current to-be-played short broadcast audio clip and the current to-be-played video clip.
The currently to-be-played short broadcast audio clip is independent of the complete video data of the target video, and the currently to-be-played video clip is a part of the complete video data and is not independent, so that the time stamps played by the currently to-be-played short broadcast audio clip and the currently to-be-played video clip are usually inconsistent, and if the currently to-be-played short broadcast audio clip is played directly according to the time stamps, the situation that the sound is inconsistent with the picture can occur. It is necessary to calculate the offset of the time stamps based on the time stamps of both. For example, as shown in fig. 5, the time stamp of the video clip a starts from 5.00, and the audio clip starts from 0.00, so that the offset present in the time stamp of the video clip a and the audio clip a is 5.00. And calculating the offset of the prime and the even to obtain the offset of the prime.
S402, playing the short broadcast audio clip to be played currently and the video clip to be played currently based on the timestamp offset.
S106, when the current video clip to be played is played, judging whether the video clip to be played exists.
It should be noted that, in the short play mode, when the current video segment to be played is played, it is determined whether a video segment to be played exists, so as to determine whether to acquire a next video segment to be played for playing. Therefore, if it is determined that there is a video clip to be played, the process returns to step S104. If it is determined that there is no video clip to be played, step S107 is performed. Of course, this is an optional manner, and it may also be determined whether the short broadcast audio data has been played completely, because the short broadcast audio segments are in one-to-one correspondence with the video segments, when determining whether the short broadcast audio data has been played completely, it may be determined whether there is a video segment to be played.
And S107, determining that all video clips are played.
According to the video playing method provided by the embodiment of the application, when the target video is requested to be played, the complete audio and video data of the target video and the short playing data of the target video are obtained. The complete audio and video data comprises synchronous complete video data and complete audio data, and the short broadcast data comprises short broadcast audio data, dotting data and audio and video synchronous data.
