+1 to both of these points. To add in my 2 cents, consumption of metadata
(APE, ID3, etc) packets seems like something that should be part of the
core avformat routines. I.e. they should transparently feed into the
AVFormatContext metadata structure. Chrome doesn't use them, so we're fine
with discarding them like I did in my patch, but forwarding them to clients
which have been told these are packets for codec X when in reality they are
metadata packets feels unfortunate.
