Hello, I'm from Solveig Multimedia team. I'm would like to use ffmpeg to
encode wmv1 wmv2 files in my tasks.

The common question: For wmv2 there is a param in src
http://ffmpeg.org/doxygen/0.6/wmv2enc_8c-source.html#l00147 
top_left_mv_flag =0 by default- what is the meaning of this flag? (it will
be available in 4-th bit of the 3-rd byte of the wmv private data in
output.)
M$ encoder makes files with this bit flag equal to 1 and seems compresses
video by diffrent algorithm.

I also need one param to be set from external iface "slice_num" as discussed
here http://forum.doom9.org/showthread.php?t=158411
wmv1
http://ffmpeg.org/doxygen/0.6/msmpeg4_8c-source.html#l00376
wmv2
http://ffmpeg.org/doxygen/0.6/wmv2enc_8c-source.html#l00046
I can make this modifications myself but I need to know how I can post these
modification to main ffmpeg source to respect LGPL license.



 

Best of luck,

Maxim Sakhankov
