[FFmpeg-devel] [PATCH] Support block-level quantization in Theora

[David Conrad]

Hi,

This mostly fixes theora_derf.ogg [1]; keyframes are good but  
interframes degrade due to a bug in libtheora when that file was  
created (inter quant matrices were assumed to be copied from intra  
when they shouldn't have been according to the spec.)

Also I reduced the number of planes in qmat to 3 because Theora/vp3  
can't have more.
