Christophe Gisquet	6b03900382	x86 dsputil: provide SSE2/SSSE3 versions of bswap_buf While pshufb allows emulating bswap on XMM registers for SSSE3, more shuffling is needed for SSE2. Alignment is critical, so specific codepaths are provided for this case. For the huffyuv sequence "angels_480-huffyuvcompress.avi": C (using bswap instruction): ~ 55k cycles SSE2: ~ 40k cycles SSSE3 using unaligned loads: ~ 35k cycles SSSE3 using aligned loads: ~ 30k cycles Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Ronald S. Bultje	e92003514d	png: move DSP functions to their own DSP context.	13 years ago
Ronald S. Bultje	c3af52fa8b	dsputil: use vertical component for drawing bottom edge. Current code only writes 8 pixels of vertical edge for YUV422, which causes MC artifacts when subsequent frames use data from that edge.	13 years ago

Justin Ruggles	395f2e70dd	dsputil: use movups instead of movdqu in ff_emu_edge_core_sse() This allows emulated_edge_mc_sse() and gmc_sse() to be used under AV_CPU_FLAG_SSE.	13 years ago

Mans Rullgard	710b8df949	dsputil: remove ff_emulated_edge_mc macro used in one place This macro can cause problems in conjunction with the bitdepth template expansion. It was presumably added to keep source compatibility when high bitdepth support was added. However, emulated_edge_mc is a dsputil pointer and should not be called directly, so there is little reason to keep such a macro. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago

Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	8d147f1f60	For rounding in chroma MC SSSE3, use 16-byte pw_3/4 instead of reading 8 bytes and then using movlhps to dup it into the higher half of the register. Originally committed as revision 26086 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
