Anton Khirnov	a0f2946068	h264: use properly allocated AVFrames	10 years ago
Anton Khirnov	249796e256	svq3: initialize some required H264Context fields. They are no longer initialized in ff_h264_decode_init() since `43fd3dd`, so svq3 needs to initialize the manually. Fixes svq3 decoding, broken since `43fd3dd`.	10 years ago
Anton Khirnov	c28ed1d743	h264: move [uv]linesize to the per-slice context While it is a per-frame variable, it is only really used in the low-level decoding code, so it is more efficient to store it in the slice context.	10 years ago
Anton Khirnov	36d04801ba	h264: move the scratch buffers into the per-slice context Also change the method for allocating them. Instead of two possible alloc calls from different places, just ensure they are allocated at the start of each slice. This should be simpler and less bug-prone than the previous method.	10 years ago

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.

Martin Storsjö	1115689d54	svq3: Check for any negative return value from ff_h264_check_intra_pred_mode Also pass on any returned error code. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

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.

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.

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.
