[XviD-devel] xvid decoder for help

[Sam Lerouge]

Hello,

About two years ago, I wanted to do the same, and I didn't have to modify 
much of the xvid_decraw.c code. I suggest you take a look at the following 
threads on the XViD forum:
- 
http://www.xvid.org/modules.php?op=modload&name=phpBB2&file=viewtopic&t=1482&highlight=
- 
http://www.xvid.org/modules.php?op=modload&name=phpBB2&file=viewtopic&t=1640&highlight=

Best regards,
