Diego Biurrun	54b2ce7418	mpeg: Drop unused parameters from ff_draw_horiz_band()	11 years ago
Janne Grunau	fb0c9d41d6	avutil: remove timer.h include from internal.h Added libavutil/timer.h include to all files with {START,STOP}_TIMER.	11 years ago
Anton Khirnov	024db24912	mpegvideo: allocate edges when encoding. Allocating edges will be removed from generic code, so the encoder must handle this explicitly.	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Michael Niedermayer	950fb8acb4	avcodec/mpegvideo: fix ac/dc_val and coded_block table sizes With interlaced vc1 it was possible that accesses could happen outside these tables before this. Regression since `017e234c20` Reproduced with a sample from Mateusz "j00ru" Jurczyk and Gynvael Coldwind Fixes (again) : 480i30__codec_WVC1__mode_2__framerate_29.970__type_2__preproc_17.SIGFPE.bfa.390.wmv No releases are affected by this Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	a3a55645f0	mpegvideo: remove disabled bfin asm It has been disabled as 'broken' over 3 years ago in `b716a792`	11 years ago
Anton Khirnov	a4d0c6e050	mpegvideo: move dct_unquantize functions up to avoid forward declarations	11 years ago
Anton Khirnov	aec25b1c46	mpegvideo: split the encoding-only parts of frame_start() into a separate function This introduces some code duplication. However, much of it should go away once the decoders stop using MpegEncContext.	11 years ago
Anton Khirnov	feded990e3	mpegvideo: set reference/pict_type on generated reference frames Otherwise the generic code will unref them, which can then result in last_picture_ptr == current_picture_ptr, which causes deadlocks at least in rv40. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Ivan Kalvachev	1c63aed232	Convert XvMC to hwaccel v3 Signed-off-by: Ivan Kalvachev <ikalvachev@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	34fe125f4b	avcodec/mpegvideo_enc: fix frame skipping with intra only codecs Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	2d1f4288dd	mpegvideo: call av_frame_unref() instead of avcodec_get_frame_defaults(). This is a temporary workaround to allow deprecating avcodec_get_frame_defaults(). The proper solution will be using a properly allocated AVFrame in Picture.	11 years ago
Anton Khirnov	b06c8bce02	mpegvideo: remove an unneeded call to avcodec_get_frame_defaults(). ff_mpeg_unref_picture() already resets the frame.	11 years ago
Anton Khirnov	282c6a1a0e	mpegvideo: make ff_release_unused_pictures() static It is only called from one place in mpegvideo.c now. Also remove the remove_current parameter, which is always 1.	11 years ago
Anton Khirnov	c99307caee	mpegvideo: make frame_size_alloc() static. It is not called from outside of mpegvideo.c anymore.	11 years ago
Anton Khirnov	0b0a7a751d	mpegvideo: move encode-only parts of common_end() to encode_end()	11 years ago
Anton Khirnov	d0d111d059	mpegvideo: remove commented out cruft from ff_MPV_frame_end()	11 years ago
Anton Khirnov	381a722562	mpegvideo: split the encoding-only parts of ff_MPV_frame_end() into a separate function	11 years ago
Anton Khirnov	b7254288d2	mpegvideo: do not update last_non_b_pict_type in update_thread_context() It is used for encoding only.	11 years ago
Anton Khirnov	1f8eb69079	mpegvideo: move encoding-only initialization from common_init() to encode_init()	11 years ago
Anton Khirnov	bedf952bb8	mpegvideo: move setting encoding-only vars from common_defaults() to encode_defaults()	11 years ago
Anton Khirnov	2cab011f0f	mpegvideo: don't copy input_picture_number in update_thread_context() It is encoding-only, frame threading is not used for encoding.	11 years ago
Anton Khirnov	e62a43f6b1	mpeg4videodec: move MpegEncContext.time_increment_bits to Mpeg4DecContext The field remains in MpegEncContext for use in the encoder.	11 years ago
Anton Khirnov	ee8af2dd99	mpeg4videodec: move MpegEncContext.shape to Mpeg4DecContext	11 years ago
Kostya Shishkov	16e7b189c5	mpegvideo: Fix swapping of UV planes for VCR2	11 years ago
Anton Khirnov	a553c6a347	lavc: use buf[0] instead of data[0] in checks whether a frame is allocated data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago

Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it. Furthermore XvMC is not implemented within the hwaccel framework, but requires its own specific code in the MPEG-1/2 decoder, which is a maintenance burden.	11 years ago
Diego Biurrun	c7f7bfc9e3	Remove all Alpha architecture optimizations Alpha has been end-of-lifed and no more test machines are available.	11 years ago
Michael Niedermayer	6e87dfb589	mpegvideo: reduce whitespace differences to libav This excludes many changes that worsen readability Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	ccc7129845	lavc: deprecate FF_DEBUG_MV and remove all traces of its use It has not been actually used since `37045e4229`, when the broken vismv code was removed.	11 years ago
Luca Barbato	72072bf9de	mpegvideo: Drop a faulty assert That check is easily reachable by faulty input. CC:libav-stable@libav.org Reported-by: Torsten Sadowski <tsadowski@gmx.net>	11 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. 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
Ronald S. Bultje	c341f734e5	Convert multiplier for MV from int to ptrdiff_t. This prevents emulated_edge_mc from not undoing mvy*stride-related integer overflows. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	dcc7686ae7	avcodec/mpegvideo: drop emu edge check from chroma_4mv_motion_lowres() This is in line with the other functions Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Martin Storsjö	5f24fe82e5	mpegvideo: Initialize chroma_*_shift and codec_tag even if the size is 0 This fixes breakage in a few fate tests on certain setups (that for some reason didn't break on OS X) after the previous commit (`8812a8057`). Currently, some video streams are initialized in ff_MPV_common_init with width/height set at 0 and only changed to a proper video size with ff_MPV_common_frame_size_change later. The breakage was diagnosed by Anton Khirnov. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
