Hi,

I would like to tie 'meta' binary data to my video.

I see that for text data some people are using the Metadata API.
It would work as I need to read the data at opening, not in sync with 
the audio/video stream.

Do you think that for binary data I could (should ?) use a 
AVMEDIA_TYPE_DATA or ATTACHMENT stream ?
Is it supported by many (every ?) format ?

Or else, I was thinking to uuencode my binary data to put it in a 
Metadata value (about 10Kbytes).

What would be your suggestion ?
