Diego Biurrun	54b2ce7418	mpeg: Drop unused parameters from ff_draw_horiz_band()	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Martin Storsjö	601c2015bc	svq3: Avoid a division by zero If the height is zero, the decompression will probably end up failing due to not fitting into the allocated buffer later anyway, so this doesn't need any more elaborate check.

Ronald S. Bultje	2f6bc5f7c1	svq3: Use hpeldsp instead of dsputil for half-pel functions 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. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	ddcca4ba07	lavc: stop setting AVFrame.motion_subsample_log2 It is not used inside lavc anywhere and now it makes no sense to export it.	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago
Ronald S. Bultje	fae6fd5b87	h264/svq3: Stop using draw_edges Instead, only extend edges on-demand when the motion vector actually crosses the visible decoded area using ff_emulated_edge_mc(). This changes decoding time for cathedral from 8.722sec to 8.706sec, i.e. 0.2% faster overall. More generally (VP8 uses this also), low-motion content gets significant speed improvements, whereas high-motion content tends to decode in approximately the same time.

Matti Hamalainen	7f3624dc81	svq3: unbreak decoding `a7d2861d36` removed necessary braces.	12 years ago
Anton Khirnov	2c54155407	h264: deMpegEncContextize Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.

Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch().

Janne Grunau	288bb3da16	svq3: make slice type value unsigned to match svq3_get_ue_golomb return type	12 years ago
Janne Grunau	9a2e79116d	golomb: use unsigned arithmetics in svq3_get_ue_golomb() This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.	12 years ago

Ronald S. Bultje	45b7bd7c53	h264: disallow constrained intra prediction modes for luma. Conversion of the luma intra prediction mode to one of the constrained ("alzheimer") ones can happen by crafting special bitstreams, causing a crash because we'll call a NULL function pointer for 16x16 block intra prediction, since constrained intra prediction functions are only implemented for chroma (8x8 blocks).
