I suppose at least https://github.com/FFmpeg/FFmpeg/blob/069d2b4a50a6eb2f925f36884e6b9bd9a1e54670/libavformat/pmpdec.c#L85
"AAC not yet correctly supported" BS should be removed. Also when looking at https://github.com/FFmpeg/FFmpeg/commit/45da7a0e8f271b32202424358393aa249a939028 it looks like it is correct. It must be truncated (or it is NOT SEI, but parts of container, then who cares). Dunno. I would close this BS. It plays... Except for "No audio packets", it all looks good to me.
