ffmpeg writes PCM_S24LE to MP4 as is but ipcm atom reports PCM_S16LE.
As the result the audio stream is totally damaged.
The same behavior for PCM_S24BE -> PCM_S16BE and 32-bit PCM audio.
ffmpeg version: nightly build 20230507
How to reproduce:
{{{
% ffmpeg -i input.mp4 -c:v copy -c:a pcm_s24le output.mp4
}}}
