"================================================= ================= Greatly srs (simple rtmp server) to modify the code to support server-side code, and increase the push h.265 h.265 bare streaming client, srs server itself push does not support h.265 and h.265 rtmp protocol bare runoff srs Download:. https: //github.com/ossrs/srs (downloaded 3.0release) csdn Download: https: //download.csdn. net / download / qq_44895902 / 12405623
A. Modify srs server-side code support h.265
1) vim src / app / srs_app_source.cpp srs_error_t In this function SrsSource :: on_video (SrsCommonMessage * shared_video) to find if (SrsFlvVideo :: acceptable (shared_video-> payload, shared_video-> size!)), Jump to SrsFlvVideo: : () function defines acceptable, the following modifications are as follows:
bool SrsFlvVideo :: acceptable (char * data, int size)
{
// 1bytes required.
if (size <1)
{
Return False;
}
char frame_type = data [0];
char codec_id = frame_type & 0x0f;
frame_type = (frame_type >> 4) & 0x0f;
if (frame_type <1 || frame_type> 5) // 1 <= x <= 5
{
Return False;
}
/ * 2020-03-31 head to solve the problem * /
if (codec_id <2 || codec_id> 12) {// 2 <= x <= 7
Return False;
}
Return True;

srs server-side support for h.265 encoding modified completed, srs recompile the code ./configure && make && make install Start the server: ./objs/srs -c conf / srs.conf see if the server is started successfully: ps -ef | grep srs
II. H.265 bare increase flow push client, the push h.265 bare flows srs
Look at a demo, the project has been uploaded as shown below Note: Pull Stream Player, VLC does not support the h.265, h.265 want to play, with Daniel Live SDK: https: //github.com/daniulive/SmarterStreaming
III. The demo, verification testing
Streaming - server >> - >> pull push h.265 stream demo bare flow 1) Start srs server / nginx-rtmp-server server (there is a patch to take own support h.265) to determine the server ip: 192.168.43.49 port number: 19352) began to push the stream: cd / srs / bin directory: ./srs_h265_raw_publish xxx.h265 rtmp: //192.168.43.49: 1935 / live / livestream 25 3) Daniel SDK pull live streaming rtmp: // It can be known from the figure 192.168.43.49:1935/live/livestream normal playback, description modify srs support server-side code encoding h.265
Four .ffmpeg command to extract the bare stream from MP4 files
1) h.264 encoded MP4 file ffmpeg -i input.mp4 -vcodec copy -an output.h264 2) h.265 encoded MP4 file ffmpeg -i xxx.mp4 -vcodec copy -an -bsf hevc_mp4toannexb -f hevc xxx .hevc "
