Jason Garrett-Glaser	1e73967950	VP8: partially inline decode_block_coeffs Avoids a function call in the case of empty DCT blocks (most of the time). Originally committed as revision 24691 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	ffbf0794f9	Fix 100L in r24689 Accidentally committed some timing code. Originally committed as revision 24690 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	afb54a85c3	VP8: simplify decode_block_coeffs to avoid having to track nonzero coeffs Slightly faster. Originally committed as revision 24689 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	b0d5879513	VP8: slightly faster DCT coefficient probability update Originally committed as revision 24687 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	476be414a4	VP8: make another RAC call branchy 1-2 clocks faster. Originally committed as revision 24683 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	0908f1b945	VP8: unroll partition type decoding tree ~34% faster partition type decoding. Originally committed as revision 24681 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c5dec7f137	VP8: unroll splitmv decoding tree Much faster splitmv mode decoding. Originally committed as revision 24680 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	23117d69c1	VP8: unroll MB mode decoding tree ~50% faster MB mode decoding, plus eliminate a costly switch. Originally committed as revision 24679 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	370b622a45	VP8: eliminate a dereference in coefficient decoding Originally committed as revision 24671 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	f311208cf1	VP8: much faster DC transform handling A lot of the time the DC block is empty: don't do the WHT in this case. A lot of the rest of the time, there's only one coefficient: make a special DC-only transform for that case. When the block is empty, don't incorrectly mark luma DCT blocks as having DC coefficients. Originally committed as revision 24670 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	827d43bb9d	VP8: move zeroing of luma DC block into the WHT Lets us do the zeroing in asm instead of C. Also makes it consistent with the way the regular iDCT code does it. Originally committed as revision 24668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Pascal Massimino	d2840fa49c	only store intra prediction modes on the boundary for keyframes, not as a plane. inter-frame behaviour unchanged. Originally committed as revision 24664 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	10bf2eebbe	VP8: simplify token_prob handling ~1.5% faster decode_block_coeffs Originally committed as revision 24659 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Pascal Massimino	c22b4468a6	prevent access to vp8_coeff_band[16] Originally committed as revision 24656 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Pascal Massimino	a8ab0cccf7	b0rk3d FATE + black helicopters hissing -> rolling back to r24556 and sleeping Originally committed as revision 24559 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Pascal Massimino	62d1f7864e	perform the clipping on luma_dc_qmul[1] and chroma_qmul[0] earlier Originally committed as revision 24558 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Pascal Massimino	e7e81959d6	save some copies by moving some fields out of proba[2] Originally committed as revision 24557 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	fca05ea8a0	VP8: add missing free Fixes a tiny memory leak. Originally committed as revision 24504 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	28e241de5d	Fix r24445: Instead of needlessly initialising a variable, silence the warning. Originally committed as revision 24498 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
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	7697cdcf95	VP8: Use vp56_rac_get_prob_branchy when the bit is only used by an if() Originally committed as revision 24469 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	13a1304bb3	Add myself to VP8 copyright and maintainers. Also add Ronald to maintainers. Originally committed as revision 24464 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	414ac27d8f	VP8: always_inline some things to force gcc to do the right thing Mostly seems to help in the MC code, which gets a hundred cycles faster. Originally committed as revision 24463 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	06d50ca804	VP8: use AV_RL24 instead of defining a new RL24. Originally committed as revision 24462 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	9fddd14a8e	VP8: Slightly faster MV selection Don't clamp best mv unless it's actually used. Originally committed as revision 24461 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	14767f35ed	VP8: use AV_ZERO32 instead of AV_WN32A where relevant Originally committed as revision 24460 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	09959ec46e	VP8: eliminate redundant code in r24458 Originally committed as revision 24459 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	a71abb714e	VP8: shave a few clocks off check_intra_pred_mode Originally committed as revision 24458 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	0087aa47d0	VP8: fix broken sign bias code in MV pred Apparently the official conformance test vectors don't test this feature, even though libvpx uses it. Originally committed as revision 24456 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	3ae079a3c8	VP8: optimize DC-only chroma case in the same way as luma. Add MMX idct_dc_add4uv function for this case. ~40% faster chroma idct. Originally committed as revision 24455 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	3df56f4118	VP8: Clean up some variable shadowing. Originally committed as revision 24454 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	8a467b2d44	VP8: 30% faster idct_mb Take shortcuts based on statistically common situations. Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT blocks are common. TODO: tie this more directly into the MB mode, since the DC-level transform is only used for non-splitmv blocks? Originally committed as revision 24452 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	ef38842f0b	VP8: smarter prefetching Don't prefetch reference frames that were used less than 1/32th of the time so far in the frame. This helps speed up to ~2% on videos that, in many frames, make near-zero (but not entirely zero) use of golden and/or alt-refs. This is a very common property of videos encoded by libvpx. Originally committed as revision 24451 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c25c776708	VP8: clear DCT blocks in iDCT instead of using clear_blocks. ~0.3% faster overall. Originally committed as revision 24448 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	b74f70d646	VP8: avoid a memset for non-i4x4 blocks with no coefficients Originally committed as revision 24447 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	145d31865d	Get rid of more unnecessary dereferences in VP8 deblocking Originally committed as revision 24446 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	867215336d	Shut up an uninitialized variable GCC warning in VP8. Originally committed as revision 24445 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c4211046d2	Smarter VP8 prefetching Prefetch all refs (including altref), but only if they've been used so far this frame. ~2.5% faster overall. TODO: Do something even smarter, like using how often each ref has been used so far, so that a couple blocks of a rarely-used ref don't force us to prefetch it. Originally committed as revision 24444 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	8cfae560ad	Fix stupid bug in VP8 prefetching code Originally committed as revision 24443 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
Jason Garrett-Glaser	d292c3455e	Eliminate some repeated dereferences in VP8 inter_predict Originally committed as revision 24438 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	b946111fde	Eliminate a pointless memset for intra blocks in P-frames in VP8 Originally committed as revision 24429 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	b9a7186bf4	VP8: Don't store segment in macroblock struct anymore. Not necessary with the previous patch. Originally committed as revision 24427 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c55e0d34ba	Convert VP8 macroblock structures to a ring buffer. Uses a slightly nonintuitive ring buffer size of (width+height*2) to simplify addressing logic. Also split out the segmentation map to a separate structure, necessary to implement the ring buffer. Originally committed as revision 24426 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	968570d65f	Calculate deblock strength per-MB instead of per-row Gives better cache locality, since the VP8Macroblock structs are still in cache. Inspired by the way x264 does it. Originally committed as revision 24417 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	d1c58fce20	Avoid tracking i4x4 modes in P-frames in VP8 As in the previous commit, they aren't used for context selection, so it saves memory this way. Originally committed as revision 24416 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	158e062c95	Avoid useless fill_rectangle in P-frames in VP8 In VP8, i4x4 only uses contexts based on neighbors in I-frames. Originally committed as revision 24415 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	7bf254c41d	Optimize partition mv decoding in VP8 Originally committed as revision 24414 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c0498b3031	Take shortcuts for mv0 case in VP8 MC Avoid edge emulation -- it isn't needed if there isn't any subpel. Originally committed as revision 24413 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
