tags

Summary of the bug:
I can add an ffmetadata file to an MP4 file to include movie chapters. But
global tags for the whole movie, like title and comment, in the same file
are not added.
How to reproduce:
(Windows 10 64bit)
> qaac64 -V 64 -q 1 -o PAL.m4a PAL.avs
> x264 --crf 25 --preset slow --nr 500 --colormatrix bt709 --transfer
bt709 --colorprim bt709 --qpfile PAL.qp -o PAL.v.mp4 PAL.avs
> ren PAL.v.mp4 PAL.m4v
> ffmpeg -i PAL.m4v -i PAL.m4a -i PAL.ffmetadata -map_metadata 1 -c:v copy
-c:a copy -movflags +faststart PAL.mp4
Chapters are read from the file PAL.ffmetadata, successfully inserted in
the MP4 file, media players can handle the chapters (the "Menu" entry is
reported even **twice** - is that necessary at all?), but global tags
"title" and "comment" in the same file are ignored.
Sample files and some console outputs (analysis logs by "MediaInfo -f" and
"MP4Box -infox") are attached in a ZIP archive.
