Push and Playback Testing

Push Testing

ZLMediaKit supports RTSP/RTMP/RTP push streaming. Typically, OBS/FFmpeg is used for push testing. The FFmpeg push commands are as follows:

1. Pushing via RTSP:

   # H.264 push
   ffmpeg -re -i "/path/to/test.mp4" -vcodec h264 -acodec aac -f rtsp -rtsp_transport tcp rtsp://127.0.0.1/live/test
   # H.265 push
   ffmpeg -re -i "/path/to/test.mp4" -vcodec h265 -acodec aac -f rtsp -rtsp_transport tcp rtsp://127.0.0.1/live/test
   

2. Pushing via RTMP:

   # If FFmpeg is not installed, you can also use OBS for push streaming
   ffmpeg -re -i "/path/to/test.mp4" -vcodec h264 -acodec aac -f flv rtmp://127.0.0.1/live/test
   # The RTMP standard does not support H.265, but there are domestic extensions. If you want FFmpeg to support RTMP-H.265, please follow the instructions in this article to compile: https://github.com/ksvc/FFmpeg/wiki/hevcpush
   

3. Pushing via RTP:

   # H.264 push
   ffmpeg -re -i "/path/to/test.mp4" -vcodec h264 -acodec aac -f rtp_mpegts rtp://127.0.0.1:10000
   # H.265 push
   ffmpeg -re -i "/path/to/test.mp4" -vcodec h265 -acodec aac -f rtp_mpegts rtp://127.0.0.1:10000
