[FFmpeg-devel] [PATCH 0/2] avformat/mov: add support for parsing tmpo atom

[Moritz Barsnick]

Adds mov_metadata_int16() for parsing 16-bit integer atoms, and
a corresponding call in mov_read_udta_string.

The atom's value is mapped to the "tmpo" metadata key, which is the
same one as used by avformat/movenc. I couldn't find a concise doc
about what it should map to.
https://github.com/hile/soundforest/blob/master/soundforest/tags/formats/aac.py
indicates it might be "bpm", as does
