The invention aims to provide a method for realizing the on-demand of a plurality of videos according to time based on video source information joint, which ensures that the video playing operation is convenient and fast, a client does not need to interact with a file server, and the flow is saved.
In order to achieve the purpose, the technical scheme of the invention is as follows: a method for realizing the on-demand of a plurality of videos according to time based on the information joint of video sources comprises the following steps:
s1, storing the video file on a file server;
s2, adding a media proxy server and a streaming media server between the file server and the client browser;
s3, the client browser sends the time point of starting playing to the media proxy server;
s4, the media proxy server searches the video file containing the time point from the file server; after finding out the video file, the media proxy server starts to push the stream to the streaming media server from the appointed time point, and returns a stream playing address to the client browser;
s5, the client browser uses the h5 player to accept the flv format video stream to start playing;
s6, encountering the end of the video or the customer reselection time, then repeating steps S3-S5.
In an embodiment of the present invention, a specific implementation manner in which the media proxy server starts streaming to the streaming media server from a specified time point and returns a streaming address to the client browser is as follows:
(1) after finding out the video file, the media proxy server obtains the start time S corresponding to the video file, calculates the start time T of the video at the time point R requested by the client, and adopts the formula: t = R-S; and converted into seconds;
(2) separating a video stream and an audio stream from a video file;
(3) stuffing the video stream and the audio stream into a pipeline, and jumping to the starting time T calculated in the step (1);
(4) for the video stream, a first key frame after the time point needs to be found, traversal is started from the first frame, if the first key frame is not found, the first key frame is abandoned until the first key frame is found, a time point U corresponding to the key frame is recorded, and the audio stream is made to jump to the time point;
(5) encapsulating the video stream and the audio stream starting from the time point U into an FLV format;
(6) acquiring the address of a streaming media server and starting pushing;
(7) and the client browser acquires a stream playing address and starts to pull and play the stream.
In an embodiment of the present invention, the process of starting streaming from a specified time point by the media proxy server to the streaming media server and returning a streaming address to the client browser further includes:
(8) and (4) if the video file is played to the end, recording the playing time, taking the time as a time point R requested by a new client, and returning to the step (1).
In one embodiment of the present invention, in step (2), the video file is an mp4 video file.
Compared with the prior art, the invention has the following beneficial effects:
1. the method is convenient and fast to operate, the client does not need to interact with the file server, and does not need to know whether the file server has files, namely, the method carries out on-demand according to time periods and does not need the front end to obtain a video directory;
2. the flow is saved, and the client does not need to download a complete video file and plays the video file where the video file is downloaded.
3. The speed is improved, the flv protocol is used for packaging the video, compared with the hls protocol, the flv protocol does not need to slice the video, the speed is inherently faster than hls, the hls delay is 6-10 seconds through tests, and the flv delay is within 3 seconds.

FIG. 2 is a schematic diagram of a method for implementing a plurality of videos on demand according to time based on video source information splicing according to the present invention.
Detailed Description
The technical scheme of the invention is specifically explained below with reference to the accompanying drawings.
As shown in fig. 2, the method for implementing a plurality of videos on demand according to time based on video source information splicing of the present invention comprises the following steps:
s1, storing the video file on a file server;
s2, adding a media proxy server and a streaming media server between the file server and the client browser;
s3, the client browser sends the time point of starting playing to the media proxy server;
s4, the media proxy server searches the video file containing the time point from the file server; after finding out the video file, the media proxy server starts to push the stream to the streaming media server from the appointed time point, and returns a stream playing address to the client browser; the specific implementation mode is as follows:
(1) after finding out the video file, the media proxy server obtains the start time S corresponding to the video file, calculates the start time T of the video at the time point R requested by the client, and adopts the formula: t = R-S; and converted into seconds;
(2) separating a video stream and an audio stream from a video file;
(3) stuffing the video stream and the audio stream into a pipeline, and jumping to the starting time T calculated in the step (1);
(4) for the video stream, a first key frame after the time point needs to be found, traversal is started from the first frame, if the first key frame is not found, the first key frame is abandoned until the first key frame is found, a time point U corresponding to the key frame is recorded, and the audio stream is made to jump to the time point;
(5) encapsulating the video stream and the audio stream starting from the time point U into an FLV format;
(6) acquiring the address of a streaming media server and starting pushing;
(7) and the client browser acquires a stream playing address and starts to pull and play the stream.
(8) And (4) if the video file is played to the end, recording the playing time, taking the playing time as a time point R requested by a new client, and returning to the step (1).
S5, the client browser receives the flv format video stream to start playing by using the h5 player;
s6, encountering the end of the video or the customer reselection time, then repeating steps S3-S5.
Compared with the existing video playing mode, the method for realizing the on-demand of a plurality of videos according to time based on video source information joint has the following differences;
1. the invention realizes the on-demand according to the time period without the need of the front end to obtain the video directory;
2. without playing using the HLS protocol, HLS is slower than FLV and has higher requirements on network quality. And because the HLS protocol is not used, splicing the m3u8 file and cutting the small video file on the server side are not needed.
The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
