The invention discloses a live broadcast and time shifting playing method and system. The method comprises the following steps: using an open source nginx server to realize an http (Hyper Text Transport Protocol) service and a file slice function required by live broadcast and time shifting; through a rtmp protocol, uploading audio and video data to the nginx server by a video source, and slicing the audio and video data into ts files through a slice module, and generating an m3u8 file; and developing a file and play message record module to record ts file information generated by each live broadcast, and then transmitting required ts files to different play requests according to live broadcast and time shifting request information, play record information and file record information; therefore, an efficient live broadcast and time shifting server can be realized simply and rapidly.
Description
Technical field
The present invention relates to direct broadcast time-shift technical field, particularly relate to a kind of direct broadcast time-shift player method and system.
Background technology
So-called time shift, refers to that spectators can arbitrarily play back the live content of time in the past. A kind of new business that time shift is live combining with program request and is formed, is supplementing of live broadcast service. User is when watching programme televised live, and midway can be suspended, and can continue to watch from time-out later, in order to avoid missing some important plot. Technically, when suspending request, Play Server gets off section directory, when continuing to play, then adopts unicast fashion to replay the program under record.
For live program, the flow medium live system with time-shifting function can see program any time later, it is not necessary to synchronize, it is possible to suspend at any time, plays. Namely the synchronousness of program is eliminated, think when to see and just when see.
Direct broadcast time-shift, in internet television and net casts such as television IPTV, OTT, uses more and more in the environment such as monitor in real time, traditional direct broadcast time-shift streaming media server exploitation is all realized by the research staff of company oneself exploitation. This process includes the form encapsulation of audio frequency and video, the transmission of Media Stream, some the development extremely complex, consuming time such as the storage of audio frequency and video, wastes substantial amounts of time and money, and the properties of product developed also can not be guaranteed. The present invention provides a kind of simple method, it is desirable in the shortest time, realizes efficiently with the time fast as far as possible, reliable time shift direct broadcast server.
Summary of the invention
The purpose of the embodiment of the present invention is in that to propose a kind of direct broadcast time-shift player method, it is intended to solves the time-shifting function in prior art network video live broadcast service and develops problem complicated, consuming time, unstable properties.
The embodiment of the present invention is achieved in that a kind of direct broadcast time-shift player method, said method comprising the steps of:
In advance the video uploaded on nginx server is cut into the ts file specifying duration the live m3u8 file of real time modifying;
It is pre-created a file and broadcast information recorder;
HTTP service module in nginx server receives the playing request that player is submitted to, it is judged that the file type of playing request, if ts file, then ts file content is returned to player, if otherwise m3u8 file, then
Playing request is acted on behalf of by HTTP service module, is transmitted to file and broadcast information recorder;
File and broadcast information recorder receive the m3u8 file request that HTTP service module agency sends, it is judged that whether m3u8 file request is first time request, if first time request, then
Distribute a unique broadcasting ID to m3u8 file request, add on broadcast path, be then back to the Redirect Address of m3u8 file to HTTP service module, and record this direct broadcast time-shift request broadcast information;
The Redirect Address of m3u8 file is returned to player and plays out by HTTP service module, terminates;
If not first time request, then
According to the broadcasting initial time being with in m3u8 file request, find corresponding ts file, generate direct broadcast time-shift m3u8 file and return to HTTP service module, and record this direct broadcast time-shift request broadcast information;
The direct broadcast time-shift m3u8 file that file and broadcast information recorder return is returned to player and plays out by HTTP service module, terminates.
The another object of the embodiment of the present invention is in that to propose a kind of direct broadcast time-shift Play System, and described system includes nginx server, file and broadcast information recorder and player;
Described nginx server includes video segment module and HTTP service module;
Video segment module, for the video uploaded on nginx server being cut into the ts file specifying duration, and the live m3u8 file of real time modifying;
HTTP service module, for receiving the playing request that player is submitted to, it is judged that the file type of playing request, if ts file, then ts file content is returned to player, otherwise, by playing request by HTTP service module, it is transmitted to file and broadcast information recorder; It is additionally operable to the m3u8 file content by file and broadcast information recorder return and returns to player,
File and broadcast information recorder, for recording live the generated ts fileinfo in every road and the broadcasting record of each direct broadcast time-shift request; Further according to direct broadcast time-shift solicited message, transmit corresponding ts file to different direct broadcast time-shift requests;
Player, for sending video playback request and the file content corresponding video of broadcasting returned according to nginx server.
Beneficial effects of the present invention
The inventive method is increased income at present on the market by utilizing, efficient http-server nginx and section server, realizes the time-shifting function in current internet video live broadcasting business. Nginx is concurrent as height, and the http-server that low-resource takies is used widely in much large-scale audio frequency and video service provider, and reliability has also to be verified fully. And play control module as functions such as a simple section file record and user's broadcast information records, it is relatively easy that much exploitation and realization are easily a lot, thus the substantial amounts of manpower and materials cost saving exploitation. And the performance of direct broadcast time-shift server is also guaranteed.
