  Comme je disais sur IRC :
  si t’as testé et que ça passe
  + c’est valide alors que le code actuel ne l’est pas
  c’est une amélioration ;-)

• Combining more than 32 input files in FFmpeg

  17 mai 2016, par thunderblaster

  I am using FFmpeg through Node.js via fluent-ffmpeg to combine a number of small audio files into one. Each of the audio files I am combining has a delayed start time (so it’s neither merging all at the same start, nor concat’ing). I can do this successfully using aevalsrc=0 and concating my audio file to that, and then amixing everything down. However, although I couldn’t find reference to a maximum number of inputs in the documentation, I got [amix @ 0x3fcd920] Value 78.000000 for parameter 'inputs' out of range [1 - 32] when trying to amix 78 files. Clearly there is a limit of 32 input files.

  Given this limitation, I am unsure of the best way to proceed. I understand that amerge exists, but it stops after the shortest file length, so I would need to apad everything and I just tested it and determined that amerge has a limit of 64 input files, which won’t always suit my needs (I have an arbitrary number of inputs).

  I could amix 32 files, store that somewhere, amix 32 more, etc, and amix the results. I would prefer to not deal with writing temp files to disk to then have to clean up later. I considered writing the "temp" outputs to duplex Node streams and reading from them in my final mixdown, but I fear that may be rather inefficient.

  Below is what I am currently doing. If this is an XY problem and this is a dumb way to accomplish what I want, please let me know.
