Diego Biurrun	6892df9294	vp3: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.	8 years ago
Luca Barbato	da60b99a88	ppc: Restrict some Altivec implementations to Big Endian In Little Endian the vec_ld/vec_st operations work as expected only for byte-vectors.	10 years ago
Diego Biurrun	27860819d5	ppc: Consistently use convenience macro for runtime CPU detection	11 years ago
Diego Biurrun	b718b24bbe	ppc: Drop a bunch of unnecessary dsputil_altivec.h #includes	11 years ago
Diego Biurrun	a6b6501185	ppc: cosmetics: Consistently format CPU flag detection invocations	11 years ago
Diego Biurrun	a053dbfcfb	ppc: Move AltiVec utility headers out of AltiVec ifdefs Now that the headers themselves have ifdef protection this is no longer necessary and more consistent with normal include handling.	12 years ago
Ronald S. Bultje	015821229f	vp3: Use full transpose for all IDCTs This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct.

Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Martin Storsjö	d160a2fb4c	ppc: Include string.h for memset This fixes build failures on ppc machines with a compiler that supports -Werror=implicit-function-declaration. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	aeaf268e52	vp3: integrate clear_blocks with idct of previous block. This is identical to what e.g. vp8 does, and prevents the function call overhead (plus dependency on dsputil for this particular function). Arm asm updated by Janne Grunau <janne-libav@jannau.net>.

Mans Rullgard	ffdd93a25e	ppc: fix build with altivec disabled Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	28f9ab7029	vp3: move idct and loop filter pointers to new vp3dsp context This moves all VP3-specific function pointers from dsputil to a new vp3dsp context. There is no reason to ever use the VP3 IDCT where an MPEG2 IDCT is expected or vice versa. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	98db4e2a4e	PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil This will allow for easier implementation of Altivec functions in libraries other than libavcodec.	13 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Måns Rullgård	ddb8c2c0f1	PPC: move prototypes to headers and make some functions static Originally committed as revision 22267 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	454403ba55	Altivec VP3 IDCT Originally committed as revision 18949 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
