2011-02-09VP8: ARM NEON optimisations for dsp functionsMans Rullgard
This adds NEON optimised versions of all functions in VP8DSPContext. Based on initial work by Rob Clark. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit a1c1d3c003b0ec16fdb6574913781313fb2c7ab6)

2011-02-04Separate format conversion DSP functions from DSPContext.Justin Ruggles
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> (cherry picked from commit c73d99e672329c8f2df290736ffc474c360ac4ae)
2011-02-02Remove unneeded add bias from 3 functions.Justin Ruggles
DSPContext.vector_fmul_window() DCADSPContext.lfe_fir() SynthFilterContext.synth_filter_float() Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 80ba1ddb58b5923b9f36a6acd542affc4ca722eb)
2011-01-30Rearrange MpegEncContext to simplify access from asmMans Rullgard
This moves the fields needed by asm near the top, before any structs or other members which complicate the offset calculation. Modifying other structs will no longer require updating the offsets, and the asm code is slightly simpler due to the smaller offsets. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit d461a4731781e492d83ef254f9c0fbd0ce6e47eb)

Originally committed as revision 26287 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-09Update asm offsets for armLuca Barbato
This unbreak ffmpeg build on arm/elf, arm/mach-o still need an update Originally committed as revision 26286 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-09-21ARM: disable movw/movt for relocated values on Apple platformsMåns Rullgård
Apparently Apple platforms do not handle movw/movt relocations properly, leading to runtime crashes in code using them. Originally committed as revision 25150 to svn://svn.ffmpeg.org/ffmpeg/trunk

2010-08-08Split h264dsp and h264pred in configure.Jason Garrett-Glaser
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

Originally committed as revision 24096 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-08ARM: set section to .text in 'function' macroMåns Rullgård
This ensures code always goes into the .text section and avoids the need to specify it explicitly after changing sections. Originally committed as revision 24095 to svn://svn.ffmpeg.org/ffmpeg/trunk

2010-06-26ARM: fix build with TI compilerMåns Rullgård

2010-06-03ARM: check struct offsets only when they are usedMåns Rullgård
