the adaptation layer mainly requests and analyzes a specified video equipment access protocol to obtain a method for fetching the stream from the source end, and stores the information into a metadata base, thereby completing the adaptation processing of different source video streams.
The adaptation layer includes two main functions:
check _ source: and performing access detection on an input video stream source end to acquire information such as a video stream taking mode and the like.
write _ db: and writing information such as a source video streaming mode and the like into a metadata base.
On the basis of the above embodiments, preferably, the translation layer is implemented based on an ffmpeg library.
Specifically, in a single process, the iterative processing of pulling, converting and pushing of the multi-source video stream is realized based on the ffmpeg library.
(1) Pulling the video stream: and pulling the source video stream by analyzing and requesting the RTSP protocol information of different video stream sources acquired by the adaptation layer. In order to avoid the influence of network packet loss, parameters such as forced TCP transmission, 3-second timeout, 1-second delay and the like are adopted when the video stream is pulled. And obtaining the format information of the stream after pulling the video stream.
(2) Converting the video stream: reading and converting video stream frame data frame by frame, and writing the video stream frame data into a target format wrapper to complete the conversion of the video stream format. In this step, it is necessary to handle the time stamp abnormality such as no time stamp, non-monotonic increase in DTS, and larger DTS than PTS in the source video stream, and for this situation, the embodiment of the present invention adopts a policy of directly discarding the extremely abnormal frames after uniformly performing time stamp conversion.
(3) Pushing a video stream: and according to the stream format required by the client transmitted by the proxy layer, after the conversion processing of the video stream frame is completed, the video stream is pushed to the nginx proxy server for distribution through stream media protocols such as RTMP, HLS and the like.
On the basis of the above embodiments, preferably, the proxy layer is implemented based on a libervent library and a libevht library.
Specifically, an asynchronous HTTP service is constructed based on libervent and libevhtp libraries, and a series of HTTPPOST methods are provided, wherein the method comprises video stream registration, real-time video stream pulling, session state obtaining, video stream state obtaining, session closing, video stream closing and other APIs.
(1) First, the configuration information is loaded through the load _ config function, and the configuration information includes parameters such as a port of the monitoring agent service, a polling period, and an upper limit of video stream access.
(2) Then, setting request routes of different methods of the proxy service, binding a callback function, setting parameters such as the size of a request message packet, multithreading, keep-alive and the like, starting the proxy service at a specified monitoring port, and monitoring a request initiated by a client.
(3) And respectively finishing logic realization of APIs (application programming interfaces) such as video stream registration, real-time video stream pulling, session state acquisition, video stream state acquisition, session closing, video stream closing and the like in the request callback function.
Wherein: video stream registration needs to call an adaptation layer for specific execution; the video stream is pulled and needs to call a conversion layer to realize specifically; the proxy service creates a unique session identification (SessionID) for each client connection that requests success, the system calls the posix _ spawn function to start the video stream conversion sub-process and associates the SessionID with the corresponding conversion sub-process ID, and the proxy layer is responsible for maintaining these session state information.
(4) In order to ensure the safety of the video stream information, the proxy layer performs authentication and data access authority check on the request of the client. Only requests that pass the authentication check can successfully establish a session connection and access the video stream.
On the basis of the above embodiment, preferably, the metadata database is a MySQL database.
The relational database MySQL is used for storing different basic description information of the video stream, including a device serial number, a device type, a device position, a protocol type, a protocol port, a channel number, a media attribute, authentication information and the like, and is a basis for the conversion layer to access the multi-source video stream.
