Referring to fig. 1, an embodiment of the present invention provides a method for optimizing a live video, which is applied to a video playing server, where the playing server is connected to a video acquisition device and a video playing device, and the method for optimizing the live video includes:
s10) judging whether a video playing request from the video playing device is obtained;
s20) under the condition that the video playing request is obtained, first video information is obtained from the video acquisition equipment;
s30) processing the first video information to obtain a first video file, caching the first video file and forwarding the first video file to the video playing device;
s40) judging whether the first video information is played completely, and acquiring second video information from the video acquisition equipment when the first video information is played completely, wherein the second video information is continuous video information with the first video information;
s50) processing the second video information to obtain a second video file, caching the second video file and forwarding the second video file to the video playing device.
In order to avoid occupying excessive network bandwidth, when the video playing server does not acquire the video playing request sent by the user, the video playing server does not acquire the video image information acquired by the video acquisition device, so that the network bandwidth is saved.
In a possible implementation manner, a video live broadcast is performed by using an HLS scheme, a video playing server first determines whether a video playing request sent by a user through a video playing device is obtained, and after the video playing request of the user is obtained, the video playing server obtains first video information from a video acquisition device, in an embodiment of the present invention, the first video information is a media fragment file, preferably, the media fragment file is a data block with a file suffix of ts, and then the video playing server processes the first video information to obtain a first video file, for example, in an embodiment of the present invention, each media fragment file is a ts data block with a duration of 2s, and the video playing server stores all ts data blocks after obtaining a preset number of ts data blocks (for example, the preset number is 10, that is, obtaining the ts data blocks with a total duration of 20 s), and generates a corresponding m3u8 file according to the 10 ts data blocks.
In the embodiment of the invention, after the corresponding m3u8 file is generated, the video playing server also records the survival time of each ts data block and the m3u8 file, and automatically deletes the ts data block after the storage time of the ts data block reaches the survival time of the ts data block; when the m3u8 file generates ts data blocks each time, for example, the video playing server reads the corresponding m3u8 file according to the video playing request of the user and generates the corresponding ts data blocks according to the m3u8 file, at this time, the video playing server automatically updates and re-records the expiration time of the m3u8 file, and when the storage time of the m3u8 file reaches the expiration time, the video playing server automatically deletes the m3u8 file.
At this time, the video playing server forwards the first video file to the video playing device, for example, forwards the generated m3u8 file to a smart phone of a user, the smart phone calls a corresponding ts data block according to the m3u8 file to obtain corresponding video image information and performs video live broadcast, in the process of live broadcast, the video playing server also monitors whether the playing of the first video file is completed, if the playing of the first video file is completed, second video information is immediately obtained from the video capturing device, in the embodiment of the present invention, the second video information is video information temporally continuous with the first video information, for example, a ts data block temporally continuous with the ts data block corresponding to the first video information, the video playing server generates a corresponding second video file according to the second video information, for example, an m3u8 file corresponding to the second video information, the video playback server then caches the m3u8 file and forwards it to the user's smartphone for continuous video playback.
Referring to fig. 2, in a possible implementation, a user performs live video broadcast through a wechat platform on a smart phone, the user first obtains live link information through the wechat platform, then obtains an m3u8 file corresponding to a current video according to the link information, at this time, extracts a ts data block list of the current video according to the m3u8 file, obtains ts data blocks according to the list in time sequence, immediately plays the video after obtaining the ts data blocks, the smart phone continues to obtain a next ts data block while playing a previous ts data block, so that a second ts data block is immediately played after playing the first ts data block, after reading the ts data block in the current m3u8 file, the smart phone automatically reads the m3u8 file in the video playing server again, and after updating the m3u8 file in the video playing server, the smart phone obtains the ts data block from a new data address according to the updated m3u8 file, for subsequent video playback.
Further, in the embodiment of the present invention, if a new m3u8 file does not exist in the video playing server in the process that the smartphone reads the m3u8 file in the video playing server again, the video playing server automatically sends a video data request to the video acquisition device, the video acquisition device immediately sends a ts data block to the video playing server again after acquiring the video data request, and the video playing server immediately sends the generated m3u8 file to the smartphone after acquiring the ts data block, so as to provide live video broadcast for the user in time; and if the video playing server sends a response result of the video data request to the video acquisition equipment that the equipment is not on-line or does not exist, feeding back feedback information that the playing data does not exist to the smart phone.
