Ff_rtsp_setup_input_streams creates a rtsp interactive connection

Ff_rtsp_send_cmd gives priority to sending DESCRIBE instructions. The difference between Haikang and Dahua rtsp instructions is that Dahua will request authentication information RTSP/1.0 401 Unauthorized during the OPTIONS phase.

Int ff_sdp_parse (AVFormatContext * s, const char * content) parses the contents of the SDK. In fact, the data format of the code stream and all the stream information are fully known here, and there is no need to detect the stream format at all.

The sdp_parse_rtpmap function analyzes the format of the h364 bitstream and saves it in the stream stream in AVFormatContext.
