Diego Biurrun	721d57e608	vp56: Separate VP5 and VP6 dsp initialization VP5 has no arch-specific optimizations (nor will it get some in the future), so it makes no sense to try to share dsp init code with VP6.	8 years ago
Himangi Saraogi	7769be590c	vp56: Return meaningful error codes Signed-off-by: Diego Biurrun <diego@biurrun.de>	10 years ago
Diego Biurrun	f2408ec9d7	Give IDCT matrix transpose macro a more descriptive name This also avoids a macro name clash and related warning on ARM.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize 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.	11 years ago
Anton Khirnov	2e0ab4d314	vp56: stop using deprecated avcodec_set_dimensions	11 years ago
Ronald S. Bultje	93f305473f	lavc: Convert some remaining strides to ptrdiff_t	11 years ago
Diego Biurrun	239f55bf3c	vp56data: Move all data tables to the .c file	11 years ago
Ronald S. Bultje	cb7ecb7563	vp56: Use hpeldsp instead of dsputil for half-pel functions This makes vp5 and vp6 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	015821229f	vp3: Use full transpose for all IDCTs 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>	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Ronald S. Bultje	f859678f3f	vp56: Remove clear_blocks call, and clear alpha plane U/V DC only 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>	12 years ago
Diego Biurrun	79dad2a932	dsputil: Separate h264chroma	12 years ago
Ronald S. Bultje	4a73fbd9c5	vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext. The function is only used in VP3 and VP5, so no need to have it in DSPContext.	12 years ago
Ronald S. Bultje	0e02b381b4	Remove put_no_rnd_pixels_l2 function pointer for w=16 from dsputil. The function is never used.	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext 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>	12 years ago
Luca Barbato	f33b5ba63e	vp56: release frames on error Fixes CVE-2012-2783 CC: libav-stable@libav.org	12 years ago
Luca Barbato	bb675d3ac6	vp56: make parse_header return standard error codes Returning 0 for failure is misleading. CC: libav-stable@libav.org	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Mans Rullgard	28f9ab7029	vp3: move idct and loop filter pointers to new vp3dsp context 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>	13 years ago
Martin Storsjö	d1b357d78b	vp56: Add ff_ prefix to nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Måns Rullgård	5e1ba34bbb	VP56: move vp56_edge_filter to new VP56DSPContext 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	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands.

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. 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	16 years ago
