Further, in the first step, after the user initiates a video playing request, the video access unit queries a camera to be played in an RTSP streaming manner, and if the camera is not online, directly returns that the playing is failed, otherwise, directly establishes a local area network connection.

Furthermore, in the second step, on the premise of ensuring the image quality, the decoding and encoding speed of the video can be greatly improved, and the encoding and decoding capability of processing data signals input by at least 15 paths of cameras is realized.

As shown in fig. 1, the video hardware encoding and decoding and video forwarding method includes the following steps: a user initiates a video playing request through terminal equipment (such as a PC), an instruction enters a video access unit first, a camera needing to be played is inquired in an RTSP streaming mode, if the camera is not on line, playing failure is directly returned, and if not, local area network connection is directly established. Step two: after the user terminal equipment is connected with the video access unit, the main control unit calls the hard decoding unit to perform hardware decoding and encoding operations on data transmitted by the camera, and the hard decoding unit can greatly improve the decoding and encoding speed of the video on the premise of ensuring the image quality after processing the data, so that the video coding and decoding capability of processing at least 15 paths of camera videos is realized. Step three: after the hard decoding unit transmits the obtained video data stream, the main control unit calls an FFMPEG stream pushing unit command, sets stream pushing overtime time, memory cache size, decoding parameters and the like, and finally carries out stream pushing operation in an RTMP mode. Step four: the stream pushing data obtained by the FFMPEG unit is received by the video forwarding unit, and a video server framework developed by pure C + + is used in the video forwarding unit, which can encode the same data while receiving a video data stream to obtain different playing formats, for example: WEBRTC, FlV, HLS, etc., while providing at least 1000 pull services and visual interface management.
