David Conrad	ca18a478e3	VP8: Inline traversing vp8_small_mvtree Much faster read_mv_component, slightly faster overall Originally committed as revision 24470 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	fe1b5d974a	Decode DCT tokens by branching to a different code path for each branch on the huffman tree, instead of traversing the tree in a while loop. Based on the similar optimization in libvpx's detokenize.c 10% faster at normal bitrates, and 30% faster for high-bitrate intra-only Originally committed as revision 24468 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	2a38c2e99a	Eliminate a LUT in escape decoding in VP8 decode_block_coeffs Originally committed as revision 24441 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	7ed06b2be8	Simplify MV parsing, removes laying out 2 or 4 (16x8/8x8/8x16) MVs over all 16 subblocks (since we no longer need that), which should also lead to a minor speedup. Originally committed as revision 23854 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	7c4dcf8165	Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows us to use width=8/16 instead of width=4 MC functions, we can now take more advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV filter of about 10%.

Ronald S. Bultje	44c70a9b3d	Fix a typo, spotted by Diego. Originally committed as revision 23738 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	3b636f21da	Native VP8 decoder. Patch by David Conrad <lessen42 gmail com> and myself. Originally committed as revision 23719 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
