Hi all,
Atm current mp4 muxer writes non standard and itunes specific metadata.
I intend to change this behaviour and to writes these metadata only for
-f ipod output format.
3GP tags are not supported, but standardized, patch welcome ;)
If anyone can quote specs were metadata tags are defined for mp4, I'll
reenable metadata writing.
Thanks.
