• How to resolve "runOnReady command exited with code 0" when restreaming a stream using Mediamtx ?

  2 juillet 2023, par Emad Helmi

  I'm attempting to publish a stream to the RTMP port 1935 using a ffmpeg command with Mediamtx (v0.22.2). Afterward, I want to restream the mainstream to another path using the runOnReady command in the config file. However, I'm encountering an issue where the runOnReady command exits with code 0.

  


  Steps to Replicate :

  


  

  1. Use the provided docker-compose.yml file :

  


  


  version: "3.8"

name: mediamtx
services:
  mediamtx:
    image: aler9/rtsp-simple-server:v0.22.2
    container_name: media_mtx_rtsp_server
    ports:
      - "8554:8554"
      - "1935:1935"
      - "8888:8888"
      - "8889:8889"
      - "9997:9997"
      - "8000:8000"
    volumes:
      - ./configs/mediamtx/config.yml:/mediamtx.yml
      - ../volumes/hls/segments:/hls/segments


  


  

  2. Add the following path to the config.yml file :

  


  


  paths:
  show/test:
    runOnReady: ffmpeg -i rtmp://localhost:1935/show/test -c copy -f flv "rtmp://localhost:1935/compressed/test"
    runOnReadyRestart: yes


  


  

  3. Start the server using docker-compose.

  


  4. Publish an RTMP stream to the server using the following command :

  


  


  ffmpeg -re -stream_loop -1 -i files/sample-30s.mp4 -c copy -f flv "rtmp://localhost:1935/show/test"


  


  

  5. When I check the logs :

  


  


  2023/07/01 15:16:30 INF [RTMP] [conn 172.26.0.1:51044] opened
2023/07/01 15:16:30 INF [path show/test] runOnReady command started
2023/07/01 15:16:30 INF [RTMP] [conn 172.26.0.1:51044] is publishing to path 'show/test', 2 tracks (H264, MPEG4-audio-gen)
2023/07/01 15:16:30 INF [path show/test] runOnReady command exited with code 0


  


  So I can't watch the stream on the new path (/compressed/test)

  27 décembre 2013, par user2922938

  I extract 100 frames from video file and i save each frame as (.bmp) but i found that each frame format is PNG not BMP , how can I save sequence of frame (format as BMP not PNG as show in picture)in C# ?

  string name;            
  
  for ( int i = 0; i < 100; i++ )
  
  {
  
      Bitmap videoFrame = video.ReadVideoFrame( );  
  
      name = (i).ToString().PadLeft(5, '0');
  
      videoFrame.Save(@"D:\frames\" + name  + ".bmp");
  
      videoFrame.Dispose( );
  
  }
  
  
  
  video.Close( );
  
  MessageBox.Show(" Complete Convert video to sequence of image","Convert");
