FFMPEG: max size for adelay parameter

Command with large size adelay parameter throws an error

Delay must be non negative number.
Failed to configure input pad on Parsed_adelay_1
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:1

The command is:

ffmpeg -y -i input.mp4 -filter_complex "[0:a]adelay=55555555:all=1[a0];[a0]amix=inputs=1[a]" -map [a] out.mp3

How can this be solved? What's the max size for adelay parameter?

Solution

  • This was a limitation. See https://trac.ffmpeg.org/ticket/9196

    It was fixed on April 25 2021, so you'll need a later git build. Or you can use the workaround in the ticket comment #3
