[FFmpeg-devel] MetaData in Sun AU format

Hello,

I'm using the .AU audio file format and noticed that FFmpeg always put 8
zero's in the annotation field.
SOX does use the annotation field to put metadata
(Title/Author/Album/Genre/Track)

I don't think there is any precise specification for this AU annotation
field as long as it is a null terminated character string, but what SOX
does looks good.

Attached are my patches to write metadata to AU files.

Regards,

Thomas Bernard
