I'm trying partially reencode wmv8 format, but unable to set complete encoder params that was used on the source file.
there is 4 bytes of the private data.
i've found that codecs extra data depends on processors count on encoding machine(slice_num (3bits since 23 bit) as described by ffmpeg
But there is another portion of data that i'm unable to determine what does it depend on
j_type_bit - 20 bit
and
top_left_mv_flag - 21 bit
http://svn.gnumonks.org/trunk/21c3-video/ffmpeg/ffmpeg-0.4.9-pre1/libavcodec/wmv2.c
If some one can explain what is for and how can i influence on it when use wmvideo encoder 8, please, post to this thread.
