Given this file
http://bitbucket.org/svnpenn/a/downloads/superuser.mp4
I am having mixed results writing metadata. For example these commands
{{{
ffmpeg -i superuser.mp4 -c copy good.aac
ffmpeg -i good.aac -c copy -bsf aac_adtstoasc -metadata title=Confetti \
-movflags faststart good.m4a
}}}
Will generate an M4A file that plays correctly with metadata that is
recognized. However this command
{{{
ffmpeg -i superuser.mp4 -c copy -vn -movflags faststart \
-metadata title=Confetti bad.m4a
}}}
Generates a file that plays correctly, but my player does not recognize
the
metadata. Note I also tried adding `-bsf aac_adtstoasc` to the bad command
to no
avail. How can I tweak the second command to get it working?
