Anton Khirnov	56087ec0a2	h264: drop a pointless indirection	9 years ago
Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 decoder Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.	9 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

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	26ee5ca03d	h264: Get rid of unnecessary casts This gets rid of a number of warnings about casts discarding qualifiers from the pointer target, present since `7ebfb466a`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	7ebfb466ae	h264: Don't store intra pcm samples in h->mb Instead, keep them in the bitstream buffer until we read them verbatim, this saves a memcpy() and a subsequent clearing of the target buffer. decode_cabac+decode_mb for a sample file (CAPM3_Sony_D.jsv) goes from 6121.4 to 6095.5 cycles, i.e. 26 cycles faster.

Ronald S. Bultje	2ed008204d	h264: Add add_pixels4/8() to h264dsp, and remove add_pixels4 from dsputil These functions are mostly H264-specific (the only other user I can spot is bink), and this allows us to special-case some functionality for H264. Also remove the 16-bit-coeff with >8bpp versions (unused) and merge the duplicate 32-bit-coeff for >8bpp (identical). Signed-off-by: Martin Storsjö <martin@martin.st>	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().

Mans Rullgard	28fff0d974	h264: use templates to avoid excessive inlining Instead of inlining everything into ff_h264_hl_decode_mb(), use explicit templating to create versions of the called functions with constant parameters filled in. This greatly speeds up compilation of h264.c and reduces the code size without any measurable impact on performance. Compilation time for h264.c on an i7 goes from 30s to 5.5s. Code size is reduced by 430kB. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
