Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	0f53601ac6	ppc: drop unused function dct_quantize_altivec() This also allows dropping some PPC-specific ugliness from dsputil.[ch].	13 years ago
Diego Biurrun	7bb3a302fe	build: Consistently handle conditional compilation for all optimization OBJS.	13 years ago
Diego Biurrun	02c39f056a	ppc: Add/remove a number of const qualifiers to fix related warnings.	13 years ago
Diego Biurrun	72ccfb3cb7	build: ppc: drop stray leftover backslash	13 years ago
Diego Biurrun	ad0e31f134	build: prettyprinting cosmetics	13 years ago
Ronald S. Bultje	bd66f073fe	vp8: change int stride to ptrdiff_t stride. On 64bit platforms with 32bit int, this means we won't have to sign- extend the integer anymore.	13 years ago

Mans Rullgard	b034c95cc1	h264: fix ppc/altivec build Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	c2d337429c	H264: change weight/biweight functions to take a height argument. Neon parts by Mans Rullgard <mans@mansr.com>.	13 years ago
Baptiste Coudurier	76741b0e56	h264: 4:2:2 intra decoding support Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mans Rullgard	6e4a35ced9	ppc: fix 32-bit PIC build On 32-bit ppc, the GOT pointer must be loaded manually. This adds a "get_got" assembler macro to compute the GOT address. The "movrel" macro is updated to take an additional parameter containing the GOT address since no register is reserved for this purpose on ppc32. These changes have no effect on ppc64 builds. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	ca6a904656	ppc: remove redundant setting of Altivec IDCT This is already set by dsputil_init_ppc() and is best done in only one place. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	6cbf2420b9	PPC: use Altivec IMDCT only for supported sizes The Altivec IMDCT works with size 32 and higher only. 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
Diego Biurrun	1f6b9cc31d	Replace some nonstandard DEBUG_* preprocessor directives by plain DEBUG.	14 years ago
Mans Rullgard	0b5e44ed29	mpegaudiodsp: fix x86 and ppc makefiles Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	c4f5c2d6f4	Move some mpegaudio functions to new mpegaudiodsp subsystem This separation allows these functions to be used in a cleaner fashion from other codecs (e.g. qdm2) and simplifies creating optimised versions of them. Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Ronald S. Bultje	18b6a69ce9	Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." This reverts commit `f8bed30d8b`. The reason for this is that the overlap filter, which runs after IDCT, should run on unclamped values, and thus IDCT and put_pixels() cannot be merged if we want to attempt to be bitexact.	14 years ago
Alex Converse	187a537904	Convert some undefined 1<<31 shifts into 1U<<31. According to ISO 9899:1999 S 6.5.7/4: The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1× 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	d21be5f15b	cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec(). It only has Altivec functions and is not compiled if Altivec is disabled.	14 years ago
Mans Rullgard	e0e46cae37	vp8: ppc: fix invalid reads in altivec epel mc The 4-tap filters should only access one row/column before the reference block. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	381efba0ec	ppc: fix vc1 inverse transform, unbreak build GCC 4.3 and later are more particular about signedness matching in vector operations. The operations under if(rangered) were missing assignments and thus had no effect. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	f8bed30d8b	VC1: merge idct8x8, coeff adjustments and put_pixels. Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.	14 years ago
Ronald S. Bultje	ed040f35f2	Fix PPC build.	14 years ago
Ronald S. Bultje	12802ec060	dsputil: move VC1-specific stuff into VC1DSPContext.	14 years ago
Ronald S. Bultje	1da6ea3954	VC1: transpose IDCT 8x8 coeffs while reading.	14 years ago
Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	80ba1ddb58	Remove unneeded add bias from 3 functions. DSPContext.vector_fmul_window() DCADSPContext.lfe_fir() SynthFilterContext.synth_filter_float() Signed-off-by: Mans Rullgard <mans@mansr.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
Stefano Sabatini	7160bb716b	Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_ symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h. Originally committed as revision 25040 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c0ec9918b0	Remove global mm_flags variable Originally committed as revision 24909 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
