  I send video stream from mobile app over rtmp encoded with hevc to my laptop where running script ffmpeg -f flv -listen 1 -i rtmp://192.168.0.194/s/streamKey -c:v libsvtav1 -f mpegts srt://192.168.0.167:9998?mode=caller. On the desktop i have obs with media source input srt://192.168.0.167:9998?mode=listener.

  


  When i run ffmpeg script without video codec option (-c:v libsvtav1) its working fine and in obs i can see video from my phone camera. With the option i can not see video only audio.
I clearly dont understand warning message : [mpegts @ 0x55ec921d9540] Stream 0, codec av1, is muxed as a private data stream and may not be recognized upon reading..
Do I need specify codec (av1) in obs media source or my ffmpeg script is wrong ?

  


• FFmpeg streaming to Akamai like FMLE does

  21 juin 2013, par xdev.developer

  I am trying to stream video from my webcam to AkamaiHD service using ffmpeg (like it is implemented in Flash Media Live Encoder)

      ffmpeg -f dshow -i video="Webcam C110" -s 640x360 -aspect 16:9 -profile:v baseline -    pix_fmt yuv420p -vcodec libx264 -f flv "rtmp://..."

  The video is sreamed, but when I try to view it at http://mediapm.edgesuite.net/edgeflash/public/zeri/debug/Main.html?url=myplayback_url/manifest.f4m
  it is not displayed.

  I've found out that if the video is recorded using FMLE and restreamed to akamai, then HLS stream is played.

  It seems that the problem is with h.264 codec configuration, but I have found no solution yet.

  Could you please advice, how can I implement streaming like FMLE using ffmpeg ?
