| * vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-181-0/+2
| | | | | | | | | | | | | | | | 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>

* VP5/6/8: ~7% faster arithmetic decodingJason Garrett-Glaser2010-08-121-5/+5
| | | | | | | Grab from the bitstream in 16-bit chunks instead of 8-bit chunks. TODO: grab in 32-bit chunks on 64-bit systems. Originally committed as revision 24783 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP5/6/8: eliminate CABAC dependencyJason Garrett-Glaser2010-08-041-10/+3
| | | | | | | Create a custom table for VP5/6/8's renorm to avoid depending on H.264's. Saves one instruction in the arithmetic decoder as well. Originally committed as revision 24701 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Silence unused function warnings in vp56.hJason Garrett-Glaser2010-08-031-5/+5
| | | | Originally committed as revision 24684 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP5/6/8: tweak some arithcoder inliningJason Garrett-Glaser2010-08-031-16/+19
| | | | | | | Always inline the arithmetic coder, except in the case of header-parsing stuff, in which case don't inline it at all to save code size. Originally committed as revision 24677 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reindent after last commit.Alex Converse2010-07-281-1/+1
| | | | Originally committed as revision 24562 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ff_prefix non static vp56 functions.Alex Converse2010-07-281-4/+4
| | | | Originally committed as revision 24561 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Inline asm for VP56 arith coderEli Friedman2010-07-231-5/+7
| | | | | | | | | This is a lot more reliable to get cmov rather than trying to trick gcc into generating it, useful since it's 2% faster overall. Patch by Eli Friedman <eli.friedman at gmail> Originally committed as revision 24471 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Decode DCT tokens by branching to a different code path for each branchDavid Conrad2010-07-231-0/+18
| | | | | | | | | | on the huffman tree, instead of traversing the tree in a while loop. Based on the similar optimization in libvpx's detokenize.c 10% faster at normal bitrates, and 30% faster for high-bitrate intra-only Originally committed as revision 24468 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move renormalization of the VP56 arith decoder to before decoding a bitDavid Conrad2010-07-231-15/+11
| | | | | | | No difference at the moment, but allows a future branchy variant of vp56_rac_get_prob to be significantly faster Originally committed as revision 24467 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split renorm of vp56 arith decoder to its own functionDavid Conrad2010-07-231-13/+17

* Convert vp56_mv to 16-bit.Jason Garrett-Glaser2010-07-221-2/+2
| | | | | | | Saves nothing except a bit of memory/cache now, but will allow future optimizations. Originally committed as revision 24411 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 23938 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Eliminate another redundant instruction in vp56/8 arithcoderJason Garrett-Glaser2010-06-301-8/+17
| | | | | | | | | | | | | Necessary because of this GCC bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474 To do this, convert some, but not all (!) of the variables in VP56RangeCoder into local variables. If we convert c->high into a local variable, gcc gets the stupids and refuses to use a conditional move for the unpredictable main branch. TODO: dispense with this bullshit and write an asm version. Originally committed as revision 23924 to svn://svn.ffmpeg.org/ffmpeg/trunk
* CMOV-ify vp56 arithcoderJason Garrett-Glaser2010-06-301-6/+2
| | | | | | | | | This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option than a completely unpredictable branch. Hopefully this carries over to newer versions and other CPUs with conditionals. ~5 cycles saved per call on a Core i7. Originally committed as revision 23921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Optimize vp56 arithmetic decoderJason Garrett-Glaser2010-06-301-8/+9

* VP56: move vp56_edge_filter to new VP56DSPContextMåns Rullgård2010-04-301-3/+2
| | | | | | | | | | Using macro templates allows the vp[56]_adjust functions to be inlined instead of called through function pointers. The new function pointers enable optimised implementations of the filters. 4% faster VP6 decoding on Cortex-A8. Originally committed as revision 22992 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-201-1/+1
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård2010-03-061-1/+1
| | | | | | | These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Globally rename the header inclusion guard names.Stefano Sabatini2008-08-311-3/+3
| | | | | | | | | Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
