  Also add options for specifying a certificate and key, which can
  
  be used both when operating as client and as server.
  Partially based on a patch by Peter Ross.

• ffmpeg command to copy video config from ffprobe

  10 avril 2021, par quarks

  What's the command to convert an MP4 to the output format similar to a video with this ffprobe :

  I've tried

  


  ffmpeg -i "input.mp4" -c:v mjpeg -c:a pcm_s16le -an output.mp4


  


  The output however does not play with the custom player.

  


  Update :

  


  I found a file which seemed to contain some config :

  Revert "Merge commit ’8b830ee9a26d47b138f12a82085cdb372f407f1e’" (avconv : Do not try to configure filter outputs without streams)
  FFmpeg already tests for this case in configure_output_filter() and printed a
  
  clearer error message
  example :
  
  ./ffmpeg -f lavfi -i color -f lavfi -i color -filter_complex "[1]null[x],[0][1]overlay" -f null -
  
  before the merge / after the revert :
  
  Filter null has a unconnected output
  after the merge / before the revert :
  
  Output pad "default" with type video of the filter instance "Parsed_null_0" of null not connected to any destination
  
  Error configuring complex filters.
  
  Invalid argument
  This reverts commit 3e3779cd517e4d2d1f21d5eb6afdb428cd3c1aa0, reversing
  
  changes made to 0b28039a44b33753d77116691d680bd60f3bac1f.
