2013-08-15vp56data: Move all shared enum/struct declarations to common headerDiego Biurrun
2013-04-20vp56: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje
This makes vp5 and vp6 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>
2013-04-15vp3: Use full transpose for all IDCTsRonald S. Bultje
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. Signed-off-by: Martin Storsjö <martin@martin.st>
2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-02-06dsputil: Separate h264chromaDiego Biurrun
2013-01-23Drop DCTELEM typedefDiego Biurrun
It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2012-12-20lavc: introduce VideoDSPContextRonald S. Bultje
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>
2012-12-14vp56: make parse_header return standard error codesLuca Barbato
Returning 0 for failure is misleading. CC: libav-stable@libav.org
2012-12-05lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov
It's got_frame, not data size
2012-10-06Give all anonymously typedeffed structs in headers a nameDiego Biurrun
Anonymous structs cannot be forward declared and have no benefit.
2012-08-27vp56: Don't use DECLARE_ALIGN on a typedef nameDerek Buitenhuis
Instead, use it on the first member, since by definition, if any member is aligned, the whole struct must be, in order to maintain that alignment. Fixes compilation with some finicky compilers. Idea for fix from Måns Rullgård. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
2012-07-18vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard
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>
2012-01-08vp56: Drop unnecessary cabac.h #include.Diego Biurrun
2011-10-07vp6: Check for huffman tree build errorsLaurent Aimar
Signed-off-by: Janne Grunau <janne-libav@jannau.net>
2011-07-15doxygen: do not include license boilerplate in Doxygen documentationDiego Biurrun
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-11ARM optimised vp56_rac_get_prob()Mans Rullgard
Approximately 3% faster on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>
2010-08-12VP5/6/8: ~7% faster arithmetic decodingJason Garrett-Glaser
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
2010-08-05VP5/6/8: eliminate CABAC dependencyJason Garrett-Glaser
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
2010-08-03Silence unused function warnings in vp56.hJason Garrett-Glaser
Originally committed as revision 24684 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-08-03VP5/6/8: tweak some arithcoder inliningJason Garrett-Glaser
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
2010-07-28Reindent after last commit.Alex Converse
Originally committed as revision 24562 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-28ff_prefix non static vp56 functions.Alex Converse
Originally committed as revision 24561 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-24Inline asm for VP56 arith coderEli Friedman
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
2010-07-24Decode DCT tokens by branching to a different code path for each branchDavid Conrad
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
2010-07-24Move renormalization of the VP56 arith decoder to before decoding a bitDavid Conrad
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
2010-07-24Split renorm of vp56 arith decoder to its own functionDavid Conrad
Originally committed as revision 24466 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-24vp56's arith decoder's code_word is only 16 bits, no need for unsigned longDavid Conrad
Originally committed as revision 24465 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-22Much faster VP8 mv and mode predictionJason Garrett-Glaser
Originally committed as revision 24412 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-22Convert vp56_mv to 16-bit.Jason Garrett-Glaser
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
2010-07-01cosmetic: improve comment breaking at 80 colsAurelien Jacobs
Originally committed as revision 23938 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-01Eliminate another redundant instruction in vp56/8 arithcoderJason Garrett-Glaser
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
2010-07-01CMOV-ify vp56 arithcoderJason Garrett-Glaser
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
2010-07-01Optimize vp56 arithmetic decoderJason Garrett-Glaser
Negate "bits" to eliminate a negate in cache refilling. Originally committed as revision 23920 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 23915 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-22Native VP8 decoder.David Conrad
Patch by David Conrad <lessen42 gmail com> and myself. Originally committed as revision 23719 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-22Change a / 256 into a >> 8.Ronald S. Bultje
Originally committed as revision 23718 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-01VP56: move vp56_edge_filter to new VP56DSPContextMåns Rullgård
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
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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
2010-03-06Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård
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
2010-01-29Make VP5 and VP6 decoders output a qscale table to allow for more automaticReimar Döffinger
post-processing, and add a new FF_QSCALE_TYPE_VP56 for this. Originally committed as revision 21529 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-22Move array specifiers outside DECLARE_ALIGNED() invocationsMåns Rullgård

2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 16068 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-08-31Globally rename the header inclusion guard names.Stefano Sabatini
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
