• ffmpeg live stream recording stops on stream interrupt

  3 septembre 2018, par Anton Antonov

  I have to record live stream with ffmmpeg. It is easy. Here is my command line :

  ffmpeg -i /source/address> -s 320x240 -r 25 -c:v libx264 -g 125 -vb 300000 -maxrate 400000 -bufsize 600000 -profile:v baseline -deinterlace -preset veryfast -ac 2 -ar 48000 -c:a libfdk_aac -b:a 64000 -f mp4 to/dst/file>

  But my task is to make ffmpeg to stop and exit when live stream is stopped.

  Is there easy way to do this ?

  27 juillet 2020, par vkh53121Acuoly.com

  I have a socket that listen to h264 stream, I can save this stream to file and play it with ffplay.

  


  This not rtp/rtsp that wraps h264 .that only h264.

  


  I want to watch this stream live, not save to file and after that run ffplay.

  


  How can I do that with python,so that work on windows and linux

  


• Creating a live, updating video stream with ffmpeg

  15 avril 2020, par MattJHoughton

  I've set up a data stream from my webcam using the MediaSource api and set it to send data from my webcam in webm format, every 4 seconds. I then grab that on a node server, use createWriteStream to set up a pipe and start streaming !

  



  I'm stuck at converting the media from webm to a live m3u8. Below is the ffmpeg command I'm running (It's been through numerous iterations as I've tried things from the docs).

  



  const cmd = `ffmpeg
    -i ${filepath}
    -profile:v baseline
    -level 3.0
    -s 640x360 -start_number 0
    -hls_time 10
    -hls_list_size 0
    -hls_flags append_list
    -hls_playlist_type event
    -f hls ${directory}playlist.m3u8`

  const ls = exec(cmd.replace(/(\r\n|\n|\r)/gm," "), (err, stdout, stderr) => {
    if(err) {
      console.log(error);
    }

  })


  



  I can't remove the #EXT-X-ENDLIST at the end of the playlist, to keep the stream live for my web players, so when I hit play - the video plays the playlist in its current state and stops at the end.

  



  Thanks

  



  UPDATE

  



  This may be a quality/speed issue. When I reduced the quality down to ;

  



  const cmd = `ffmpeg
    -i ${filepath}
    -vf scale=w=640:h=360:force_original_aspect_ratio=decrease
    -profile:v main
    -crf 51
    -g 48 -keyint_min 48
    -sc_threshold 0
    -hls_time 4
    -hls_playlist_type event
    -hls_segment_filename ${directory}720p_%03d.ts
    ${directory}playlist.m3u8


  



  I was able to get a pixelated live video. However, it quickly crashed... Maybe this is not possible in Node/Web Browsers yet ?
