Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Fig. 1 shows a flow diagram of a video playback method 100 according to an embodiment of the present disclosure. The method 100 comprises:

s110, acquiring a program list of the video program to be played.

In some embodiments, the scheduling period of the program list may be a period of one day, for example: the playing time points from 1:00am of one day to 1:00am of the next day are a period (24h), or 6 hours are a period, and the like, and the starting and stopping playing time points of one period can be set according to specific situations.

In some embodiments, the program listings may be generated based on a user's on-demand operations. And when a user continuously requests a plurality of video programs, adding the identifications of the video programs into the program list. The video programs in the program list can be played in sequence, and the next video program is played after the playing of the previous video program is finished; and can be adjusted by the user according to the operation of the user. The program list may include not only the identifier of the video program, but also information such as the play start time, the play duration, etc. of the video program. When all the video programs in the program list are played, the program list can be automatically deleted, and the cache is released; the identification of the video program comprises the heat degree of the current video and the like; the popularity of the video can be from statistics of the on-demand volume of the user, or from statistics of a third-party platform.

In some embodiments, the videos in the program list may be sorted in order of popularity from high to low, and the video program with higher popularity is preferentially played, so as to bring a better viewing experience to the user.

And S120, determining the player type corresponding to the video in the program list.

In some embodiments, the video in the program listings may be a real-time video stream (e.g., live, etc.) transmitted over a network through a video capture device; or may be a complete video file that has been produced. Generally, the real-time video stream includes protocols (streaming media technology) such as HLS, RTMP, mms, rstp, and p2p, and the video formats corresponding to each protocol are different, for example, the live video format of HLS protocol is m3u8, and the live video format of RTMP is flv;

the complete video file which is manufactured comprises: AVI (. AVI), MKV (. MKV), MP4 (. MP4), VOB (. VOB), and the like;

it can be seen that depending on the video format (source), it is often necessary to match the various player instances to which it corresponds. Specifically, the player type corresponding to the video to be played in the program list may be determined through big data analysis, history analysis, and/or manual selection according to the video format of the video to be played.

In some embodiments, when different player instances are switched, the waiting time of a user is additionally increased, so that in the present disclosure, dynamic selection can be performed according to the player type required by the video to be played, the videos to be played in the program list are grouped, videos that can be played using the same player type are grouped into one group, and the video to be played is played according to the group, so that the time required for initialization and release of the player can be saved, and the waiting time for switching the player instances can be reduced for the user; the videos to be played in the program list may also be clustered, and the same player type in a time period is placed in a group, for example, in the time period from 9 to 13, 10 videos are included, so the videos in the time period may be clustered according to the playing sequence of the videos, the user requirement, and/or the video heat, and the like, and the videos that can be played using the same player type are grouped, that is, 3 videos of the first player, 2 videos of the second player, 3 videos of the third player, and 2 videos of the second player.

S130, based on the player type, video playing is carried out on the video program to be played in the program list.

In some embodiments, a playing environment of a current playing device (e.g., a smart tv, etc.) is analyzed to determine whether the current device supports creating multiple player instances, e.g., analyzing a model, a memory, etc. of the current smart tv;

if the current equipment supports the creation of a plurality of player instances (the memory is sufficient, all the required player instances and the television model support can be loaded at the same time), loading all the required player instances according to the program list, initializing the corresponding player instances according to the video playing sequence in the program list, and playing the video;

if the current playing equipment does not support the creation of a plurality of player instances, capturing a first frame picture of a video to be played as a scene cut animation, simultaneously initializing the player instance corresponding to the video to be played, hiding the first frame picture after the initialization is completed, and playing the video to be played.

In some embodiments, if the video to be played is the first played video, the first picture of the video to be played is acquired as the cut-scene animation, the player instance corresponding to the video to be played is initialized, and after the initialization is completed, the first picture is hidden and the video is played.

In some embodiments, the loaded player instance is optimized by a preset caching algorithm, and the memory space is released. For example, when the current playing device supports creation of multiple player instances, the infrequent players can be released through the LRU algorithm, so that the memory pressure is relieved; if the video to be played in the program list is dynamically selected, the player instance corresponding to the current video group is automatically released after the same group of videos are played (the videos can be played by the same player).

In some embodiments, if a user performs a video fast switching operation, the initialization and release operations of the player are suspended until the user stops the operation, the playing position of the video to be played is obtained according to the current program information, and the player corresponding to the video to be played in the program is initialized to play the video.

Further, still include:

if the player corresponding to the video to be played does not exist in the current playing equipment, transcoding the video to be played into a video format corresponding to the player already existing in the current playing equipment according to a preset transcoding rule, simultaneously capturing a first frame picture of the video to be played as a scene cut animation, and hiding the first frame picture and playing the video after the conversion is finished.

Wherein the preset transcoding rule is as follows: a rule for transcoding an original video stream (a video stream that cannot be played by a current playing device, i.e., no corresponding player instance) into a video stream that can be played by the current device; the transcoding rule comprises a transcoded code stream format, a transcoding parameter and the like; the transcoded video formats are all video formats which can be played by current equipment (playing formats supported by player examples); the parameters comprise image resolution, code rate and/or frame rate after transcoding the original video stream.

In some embodiments, when transcoding an original video stream, the image resolution of the transcoded image may be set according to specific conditions, for example, in the case that the current playing device is poor (insufficient memory, poor hardware, etc.), the image resolution of the transcoded image may be set to be a lower image resolution, for example, 352x288, which may ensure that a smoother playing effect is obtained and the phenomena of stutter and the like are reduced in the case that the device is poor; under the condition that the current device state is better (the memory is sufficient), the image resolution of the transcoded image can be set to be higher image resolution, for example 1920 × 1080, so that a clearer visual effect can be provided for a user, and the viewing experience of the user is improved.

Similarly, based on the state of the current playing device, the bitrate and the frame rate of the video stream transcoded from the original video stream can be set.

Further, still include:

in some embodiments, based on information such as the play start time and the play duration of the video to be played, the video to be played may be divided into a plurality of video files, and then played sequentially according to the play order of the video to be played, so as to reduce the waiting time of the user.

Specifically, if the size of the video to be played is larger than a first threshold, that is, the video to be played is large, and the loading time may be too long, the video to be played is cut into a plurality of video files smaller than a second threshold; the first threshold value may be set according to information such as a format of a video to be played and a memory space of the current playing device, for example, 1 GB; the second threshold value can be determined according to the playing time and/or the application scene of the video to be played;

furthermore, when the video to be played is cut, the video to be played can be cut once according to the playing time length, and can also be cut for many times according to the actual application scene. For example, a video file with a size of 1GB (1GB 1000mb) is cut into two video files of 100mb and 900mb according to the playing sequence, and in order to reduce the waiting time of the user, while the 100mb video file is played, the 900mb video file is cut again into 9 files of 100 mb.

Similarly, when the video transcoding is performed, the video to be played can be transcoded into a plurality of video formats which can be played by the current device according to the playing time, and the videos are played in sequence.

According to the embodiment of the disclosure, the following technical effects are achieved:

the player instance corresponding to the program list of the video to be played is created, so that the time for loading the player instance is reduced, and the streaming degree of video switching is improved; when the player is loaded, the first frame image of the video to be played is captured as a process animation, so that the problem of screen blackness when the player is loaded is solved, and the watching experience of a user is improved; meanwhile, the original video stream which cannot be played by the current player can be transcoded according to a preset transcoding rule, so that the transcoded original video stream can be played by the player, and the watching experience of a user is further improved.
