Michael Niedermayer	b3c3996212	avcodec: rename prores encoders Using the first names of authors sounds somewhat unprofessional and might be considered offensive which is not intended. The new names use the initials of the authors due to simplicity and the possibility to apply it consistently without the need to find political correct names for each future case where alternative codecs might exist. Also its shorter ... If someone has a better idea, like maybe 2 random letters and people prefer it then iam happy to switch to that ...

Ronald S. Bultje	b93b27edb0	dsputil: Make dsputil selectable Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	85deb51a01	h264: Only initialize dsputil if error resilience is enabled It is only used for error resilience. This allows building the h264 decoder without dsputil, if error resilience is disabled. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	62844c3fd6	h264: Integrate clear_blocks calls with IDCT The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

Martin Storsjö	e8cafd2773	h264: Clear the mb members via memset instead of using dsputil Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	6d25c9db11	dsputil: Make square put/avg_pixels functions local to h264qpel Put a copy of the 8bit functions only in dsputil, where they are used for some other things (e.g. mpeg4qpel, mspel, cavsqpel). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Christophe Gisquet	2383068cbf	x86: sbrdsp: implement SSE2 qmf_pre_shuffle From 253 to 51 cycles on Arrandale and Win64. 44 cycles on SandyBridge. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	62a1181015	h264: wait for missing slices only on frames The EC code does not support fields currently thus it makes no sense to wait for these cases (which also the check doesnt handle correctly) Fixes Ticket 2454 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Martin Storsjö	bc0522dffa	h264pred: Add a few missing const declarations for ff_cropTbl derived pointers The pointers that get assigned ff_cropTbl were made const in `9e0f14f1`, but other variables that transitively are assigned based on these variables were missed. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	d2ec6ea6c6	lavc: Move ff_cropTbl and ff_zigzag_direct from dsputil to mathtables These are widely used throughout libavcodec, nothing dsputil-specific. Change ff_cropTbl to a statically initialized table, to avoid initializing it with a function call. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	9e0f14f16c	lavc: Make pointers to ff_cropTbl const There's no point in these pointers not being const. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	610b18e2e3	x86: qpel: Move fullpel and l2 functions to a separate file This way, they can be shared between mpeg4qpel and h264qpel without requiring either one to be compiled unconditionally. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	18df366a18	vp3: Embed idct_permutation array directly in VP3DecoderContext This makes the vp3 decoder less dependent on dsputil, and will aid in making it (eventually) dsputil-independent. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	0f59845708	bfin: Make vp3 functions static Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	aa8d89536d	bfin: Don't use the vp3 idct functions if bitexact behaviour is expected In the non-bitexact mode, vp3 currently decodes to the same frame crcs as before `28f9ab702` (and the output visually looks correct). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Christophe Gisquet	e2946e5c34	x86: sbrdsp: implement SSE qmf_deint_bfly From 312 to 89/68 (sse/sse2) cycles on Arrandale and Win64. Sandybridge: 68/47 cycles. Having a loop counter is a 7 cycle gain. Unrolling is another 7 cycle gain. Working in reverse scan is another 6 cycles. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Nicolas George	0884d04dc3	lavc: fix recoded subtitles end. Text subtitles packets are not 0-terminated (and if they are, it is handled by the recoding process since 0 is a valid Unicode code point). The terminating 0 would overwrite the last payload octet. OTOH, packets must be 0-padded. Fix a problem reported in trac ticket #2431.	12 years ago
Christophe Gisquet	11774169ae	sbrdsp: unroll and use integer operations This patch can be controversial, by assuming floats are IEEE-754 and particular behaviour of the FPU will get in the way. Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference). sbr_qmf_pre_shuffle_c: 115 to 76 sbr_neg_odd_64_c: 84 to 55 sbr_qmf_post_shuffle_c: 112 to 83 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Diego Biurrun	ed16c2dbf4	h261: Remove H.261 loop filter from dsputil There is no arch-optimized version of the H.261 loop filter and there likely will never be, so the dsputil overhead does not give any benefit.	12 years ago
