Bitstream encoded huffman tables always the same
Hello all,
I've been working a little inside the Theora decoder when I found that
it seems that many videos had the very same huffman tables encoded into
their bitstreams (at least the ones that I could take my time to
dissecate). I found that the tables are listed as TH_VP31_HUFF_CODES in
the file huffenc.c. I tried to investigate a little bit more to see who
was setting the bitstream to those tables, but I ended in the fact that
this is dependent whether the function th_encode_ctl is called with
TH_ENCCTL_SET_HUFFMAN_CODES or TH_ENCCTL_SET_VP3_COMPATIBLE, but I could
figure...
