* arm: Add an option for making sure NEON registers aren't clobberedMartin Storsjö2014-01-111-0/+1
| | | | | | This is pretty much based on the same test for XMM registers. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1: arm: Add NEON assemblyMason Carter2013-12-201-0/+3

* arm: fmtconvert: Split armv6 fmtconvert code off from vfp codeDiego Biurrun2013-08-291-1/+3

* vp56: Mark VP6-only optimizations as such.Diego Biurrun2013-08-231-4/+2
| | | | | Most of our VP56 optimizations are VP6-only and will stay that way. So avoid compiling them for VP5-only builds.

* arm: Include hpeldsp_neon.o if h264qpel is enabledMartin Storsjö2013-05-301-1/+2
| | | | | | | | | A few of the h264qpel neon functions are shared with other hpeldsp functions in this file. This fixes standalone compilation of the h264 decoder on arm. Signed-off-by: Martin Storsjö <martin@martin.st>
* arm: Don't unconditionally build dsputil filesMartin Storsjö2013-05-301-14/+13
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* arm: Only build the FFT init files if FFT is enabledMartin Storsjö2013-05-301-2/+2
| | | | | | This fixes build errors in cases where FFT is disabled. Signed-off-by: Martin Storsjö <martin@martin.st>

* arm: hpeldsp: Move half-pel assembly from dsputil to hpeldspRonald S. Bultje2013-04-191-0/+8

* dsputil: Separate h264chromaDiego Biurrun2013-02-061-2/+2
|
* arm: Add mathops.h to ARCH_HEADERS listDiego Biurrun2013-01-241-0/+2
| | | | It is an arch-specific header not suitable for standalone compilation.
* dsputil: Separate h264 qpelMans Rullgard2013-01-241-0/+3
| | | | | | | | | | 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. Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-221-3/+0
| | | | | | Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.
* Move vorbis_inverse_coupling from dsputil to vorbisdspcontext.Ronald S. Bultje2013-01-191-0/+3
| | | | | Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-201-0/+5
| | | | | | | | 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(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* arm: rename ARMVFP config symbol to VFPMans Rullgard2012-12-071-2/+2
| | | | | | | This is consistent with usual ARM nomenclature as well as with the VFPV3 and NEON symbols which both lack the ARM prefix. Signed-off-by: Mans Rullgard <mans@mansr.com>
* arm: call arm-specific rv34dsp init functions under if (ARCH_ARM)Jean-Baptiste Kempf2012-10-101-6/+6
| | | | | | | Assign NEON specific function pointers after runtime check via av_get_cpu_flags(). Signed-off-by: Janne Grunau <janne-libav@jannau.net>

|
* vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-181-0/+1
| | | | | | | | 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>

* remove iwmmxt optimizationsJanne Grunau2012-03-121-3/+0
| | | | | | The were broken since August of 2010 without anyone noticing until three weeks ago. Nobody cares about it anymore and hopefully Marvell will support NEON like in the PXA978 from now on.
* aacsbr: ARM NEON optimised sbrdsp functionsMans Rullgard2012-01-281-0/+4

* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-021-0/+5

* Split h264dsp and h264pred in configure.Jason Garrett-Glaser2010-08-071-3/+4
| | | | | | | | | Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions but not the weight/loopfilter functions. This should reduce the size of builds with one of these derivatives but without H.264 decoding itself. Originally committed as revision 24741 to svn://svn.ffmpeg.org/ffmpeg/trunk
