Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it.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
Michael Niedermayer	a0c6c8e53e	Revert "Merge commit of 'vdpau: remove old-style decoders'" This reverts commit `bf36dc50ea`, reversing changes made to `b7fc2693c7`. Conflicts: libavcodec/h264.c Keeping support for the old VDPAU API has been requested by our VDPAU maintainer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Martin Storsjö	f1e9398621	lavc: Rename avpriv_mpv_find_start_code after moving out from mpegvideo Also move the declaration to internal.h, and add restrict qualifiers to the declaration (as in the implementation). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	0163ad66e1	mpeg2: 12LSB w/h of 0 is not allowed in compliant videos thus this also needs AV_EF_COMPLIANT Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	ce0124acac	mpeg12: do not fail on zero dimensions in the sequence header. The total frame size is a combination of the 12 bits in the sequence header and 2 more bits in the the sequence extension. While the specification explicitly forbids the dimensions from the sequence header from being 0 (thus ruling out multiples of 4096), such videos apparrently exist in the wild so we should attempt to decode them. Based on a patch by Michael Niedermayer <michaelni@gmx.at> Fixes Bug 416.	12 years ago

Diego Biurrun	5f401b7b71	Add missing error_resilience includes to files that use ER	12 years ago
Ronald S. Bultje	8d061989dd	lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecs Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec. Copying specific lists in each codec fixes that. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Reimar Döffinger	c65eb7907c	mpeg12: Fix non-hwaccel VDPAU decode. Previously avctx->hwaccel would have been set to a dummy value, now an explicit check is necessary instead. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Anton Khirnov	1d0feb5d1a	mpegvideo: split ff_draw_horiz_band(). Split out dependency on MpegEncContext.	12 years ago

Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago

Anton Khirnov	5823686261	mpeg12: do not decode extradata more than once. Fixes CVE-2012-2803. CC: libav-stable@libav.org	12 years ago
Janne Grunau	f1d8763a02	mpegvideo: allocate scratch buffers after linesize is known Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.	12 years ago
Michael Niedermayer	0af7ccd9e2	mpeg12: move current_picture_ptr reset to the end of decode_frame. This fixes passing fields instead of frames into the decoder. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	8824a9ed22	mpeg12: clean current picture ptr. This avoids having a stray pointer left that may not represent the current picture and state. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Heesuk Jung	25b7aa980b	Fix bit_rate in MPEG1/2 Video In ISO/IEC 13818-2, bit rate is differently determined according to video type 1) MPEG1 Video Bit_rate and vbv_delay are set to 3FFFF and FFFF respectively to indicate variable bitrate. Other values are for constant bitrate. VBV is only defined for constant bit rate operation. Ths STD supersedes the VBV model for vbr. 2) MPEG2 Video Even if the bitrate is constant, the value of bit_rate may not be the actual bitrate since bit_rate need only be an upper bound to that actual bitrate. VBV is only defined for variable bit rate operation. Constant bit rate is viewed as a special case of vbr. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Martin Storsjö	eaa9b2e66c	avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tab This table doesn't need to be shared with libavformat any longer. Add mpeg12 to the name to make it less ambiguous, while renaming it. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Anton Khirnov	d9a2e87b1c	mpeg12: move mpeg_decode_frame() lower Avoids a forward declaration of decode_chunks().	12 years ago
Reimar Döffinger	3905caf251	Document that the MPEG12 "fast" functions can read out of bounds. This is intentional (and a reason why fast usually should not be used), but a few people sent patches to "fix" this recently so it would be better to document this. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Michael Niedermayer	2f6f2f4f73	mpeg12dec: move checks out of decode picture coding extension. Fixes out of array reads Fixes Ticket1330 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
