[FFmpeg-devel] FFMPEG/GPAC compatibility for mp4 'text' box

[Romain Bouqueau]

Dear FFMPEG developers,

I am a GPAC (gpac.sourceforge.net) maintainer, trying to make our 
frameworks compatible :)

This mail concerns the implementation of the Apple-specific 'text' box. 
We implemented it following this specification: 
http://developer.apple.com/library/mac/#documentation/QuickTime/QTFF/QTFFChap3/qtff3.html#//apple_ref/doc/uid/TP40000939-CH205-BBCJAJEA

FFMPEG generates streams using this 'text' box. However this leads to 
"extra NULL bytes" at the end of 'text' boxes which are inconsistent 
with the above mentioned spec.

Can any of you give me a pointer to the specification your implement is 
based on?

Or can you give me the contact to the developper of this part? I found 
these related commits using svn-blame: r11638 (reimar), r16531 (conrad).

Thanks!
