* vp56: Return meaningful error codesHimangi Saraogi2015-02-14
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* Give IDCT matrix transpose macro a more descriptive nameDiego Biurrun2014-02-27
| | | | This also avoids a macro name clash and related warning on ARM.
* lavc: Edge emulation with dst/src linesizeRonald S. Bultje2013-11-15
| | | | | | Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.
* vp56: stop using deprecated avcodec_set_dimensionsAnton Khirnov2013-10-31
|
* lavc: Convert some remaining strides to ptrdiff_tRonald S. Bultje2013-10-15
|
* vp56data: Move all data tables to the .c fileDiego Biurrun2013-08-15
|
* vp56: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje2013-04-19
| | | | | | This makes vp5 and vp6 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>
* vp3: Use full transpose for all IDCTsRonald S. Bultje2013-04-15
| | | | | | | | | | | 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>
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08
|
* vp56: Remove clear_blocks call, and clear alpha plane U/V DC onlyRonald S. Bultje2013-02-19
| | | | | | | | The non-alpha and alpha-Y planes are cleared in the idct_put/add() calls. For the alpha U/V planes, we only care about the DC for entropy context prediction purposes, the rest of the data is unused. Signed-off-by: Martin Storsjö <martin@martin.st>
* dsputil: Separate h264chromaDiego Biurrun2013-02-06
|
* vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext.Ronald S. Bultje2013-01-21
| | | | | The function is only used in VP3 and VP5, so no need to have it in DSPContext.
* Remove put_no_rnd_pixels_l2 function pointer for w=16 from dsputil.Ronald S. Bultje2013-01-19
| | | | The function is never used.
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | 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>
* vp56: release frames on errorLuca Barbato2012-12-14
| | | | | | Fixes CVE-2012-2783 CC: libav-stable@libav.org
* vp56: make parse_header return standard error codesLuca Barbato2012-12-14
| | | | | | Returning 0 for failure is misleading. CC: libav-stable@libav.org
* lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov2012-12-04
| | | | It's got_frame, not data size
* lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov2012-12-04
| | | | It will be useful in the upcoming transition to refcounted AVFrames.
* Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov2012-10-08
|
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07
|
* vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-18
| | | | | | | | 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>
* vp56: Add ff_ prefix to nonstatic symbolsMartin Storsjö2012-02-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>

* VP56: move vp56_edge_filter to new VP56DSPContextMåns Rullgård2010-04-30
| | | | | | | | | | 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 Biurrun2010-04-20
| | | | | | | | 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
