Subject: [FFmpeg-devel] metadata (.m4a): tag 'tmpo' is not handled
Date: Thu, 1 Jun 2023 11:48:11 -0700
Message-ID: <CAENuUCDkh9=c5b-gw8thUU9TxKHV_E=gEKwE+sOMHzW9BF83-w@mail.gmail.com> (raw)

Versions:
Linux: 4.3.6-0+deb11u1
Windows: 5.1.2-full_build-www.gyan.dev
The 'tmpo' metadata tag within a .m4a audio file is not recognized by
ffmpeg and is never processed or output. Neither the command line
interface nor the api returns this tag.

Apologies if this has already been fixed.
