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.

Mans Rullgard	e9d817351b	dsputil: Separate h264 qpel The sh4 optimizations are removed, because the code is 100% identical to the C code, so it is unlikely to provide any real practical benefit.

Mans Rullgard	a617c6aaa3	dsputil: update per-arch init funcs for non-h264 high bit depth 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

Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	ccf22d3ed1	Merge has_altivec() function into mm_support(), remove it and use mm_support() instead. Reduce complexity and simplify pending move to libavutil. Originally committed as revision 25074 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2829ce4b40	Remove PPC perf counter support This functionality is better accessed through tools like oprofile. Originally committed as revision 23808 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4693b031a3	Move H264 dsputil functions into their own struct This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code.

Add C version of ff_h264_idct8_dc_add in AltiVec so that ff_h264_idct8_add_altivec can be used. Originally committed as revision 16311 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
