• ffmpeg filter_complex concat never completes

  10 juillet 2020, par seawolf

  I am trying to concatenate mp4 files into a single file. I am attempting to use the concat filter directly for reasons independent from this question (so -i list.txt is not a valid solution). All video files in question are between 4 and 20 minutes in length.

  


  What I am executing :

  


  % ffmpeg -i f01.mp4 -i f02.mp4 -filter_complex "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output.mp4


  


  This is my understanding of the form of this command from references such as FFmpeg Filters Documentation : concat and Concatenate Videos Together Using FFMPEG !.

  


  What happens :

  


  ffmpeg gives a lot of output as it checks the metadata for each stream and then begins processing. After a short duration (several seconds to a minute or so, seems to be prortional to the duration of the first video) I start seeing messages like this :

  


  More than 1000 frames duplicated
More than 10000 frames duplicated     512kB time=00:00:00.12 bitrate=32771.0kbits/s dup=33365 drop=0 speed=0.00449x
More than 100000 frames duplicated   1280kB time=00:00:00.17 bitrate=61442.1kbits/s dup=66730 drop=0 speed=0.00272x


  


  ... and then the process never completes. If I leave my computer running for 24 hours, ffmpeg is still using max available CPU (200-300%). The output file is 48 bytes in length.

  


  Note : the inputs are only a few minutes each, so individually re-encoding the inputs would take only a few minutes each.

  


  Note : if I change the command to use f01.mp4 for both source 0 and source 1, the command completes as expected in under 5 minutes :

  


  % # example that works:
% # note, however, that this just repeats the same source twice
% ffmpeg -i f01.mp4 -i f01.mp4 -filter_complex "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output.mp4


  


  Full output :

  


  Here is the complete output of a run in case it's helpful :

  


  % ffmpeg -i f01.mp4 -i f02.mp4 -filter_complex "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output.mp4

  avformat/movenc : write the mdcv atom by default
  The mdcv atom isn't in ISO/IEC 14496-12:2015 but it is expected to be
  
  added soon. See :
  
  http://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/259529.html
  The mdcv atom is already parsed in FFmpeg in mov.c.
