[FFmpeg-devel] h263 - svq3 optimizations

h263 and sorenson spark have some common elements. Both have picture,
MB and block layers. And it seems that block layer is also very
similar between those two codecs.

Do you think it would make sense to work on transcoding optimizations
between those two codecs? There would be picture and macroblock
adaptations, but for block layer, the only thing to modify is escape
codes (I think).

or is it too specific? I would understand that input/output codecs
combinations optimizations could bring, if possible yet, an other
layer of complexity in ffmpeg, but IIRC, optmizations are welcome. (or
maybe is it just asm optmizations...)

Thank you,
