[FFmpeg-user] Concat demuxer avoid injecting additional silent packets

[Ronak]

Hi,

I’m trying to concatenate a bunch of audio only MP4s together using FFmpeg’s concat demuxer.

When I tested this with concaving 4 MP4 files into a larger one, FFmpeg seems to inject a variable amount of audio samples between concatenated files.

Is there a way to avoid having FFmpeg inject those additional silent packets while concatenating?

Does FFmpeg inject this silence regardless of what output there is? (Raw AAC vs AAC in MP4).
