• Could not find codec parameters for stream 0 (Video : hevc, none) : unspecified size

  5 avril 2020, par bzc0fq

  I try to use ffmpeg to feed ffserver on CENTOS 6.10. When I run ffmpeg on stream I got an error message : Could not find codec parameters for stream 0 (Video : h264, none) : unspecified size.

  



  The full ffmpeg output is here :

  I tested the stream with vlc on windows and it looks it works fine.


  



  Any hints on the issue ?

• Reencode videos from 30fps to 60fps using ffmpeg

  2 avril 2020, par RonPringadi

  If I have an mp4 with 30 fps, how do I re-encode it to 60 fps using ffmpg without making the movie speeding up faster (still looking normal) ?

  



  My ffmpeg

• Rails FFMPEG - convert to webm gives error for encoder 'libvpx-vp9'

  7 mai 2019, par Milind

  I am testing video conversion to convert video file into mp4 and webm.
  I have also setup ffmpeg and compiled properly.Mp4 conversion succeeds but webm breaks always complaining as -

  The encoder 'libvpx-vp9' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

  its strange as I aready have vp8 present -
