RTMP stream publisher

Feature

  1. Hardware acceleration, support Intel HD graphics/Nvidia Jetson series
  2. RTSP/v4l2/custom FPGA pull, rtmp push
  3. much higher performance v4l2 element, support YUYV and MJPEG
  4. hevc in rtmp

Performance

hardware platform input output cpu usage process latency
Jetson Xavier NX v4l2,1280*720,YUYV,30fps rtmp,h264 high yuv420p,640*360,30fps,2Mbps 10% proctime.png

Latency explain

process: add timestamp -> change video resolution -> video encode

Jetson Xavier NX, add timestamp uses about 3ms, video resolution change uses about 5ms and video encode uses about 3ms.
