Janne Grunau	6d93307f8d	mpeg12: check scantable indices in all decode_block functions Add checks to the fast functions used with CODEC_FLAGS2_FAST and move the check for all other functions to before the invalid memory is accessed. Fixes https://trac.videolan.org/vlc/ticket/9713 with CODEC_FLAGS2_FAST. CC: libav-stable@libav.org	11 years ago

Diego Biurrun	7b9780e7bf	mpeg12dec: Remove unused swap_uv member from Mpeg1Context	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Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it.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
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago

Rémi Denis-Courmont	578ea75a9e	vdpau: remove old-style decoders Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Rémi Denis-Courmont	93a51984a2	mpeg12: Ignore slice threading if hwaccel is active Slice threading does not work with hardware acceleration, as decoding is per-picture. This fixes Bugzilla #542. Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Janne Grunau	bf20cdbd86	mpeg12: skip frames consistently The decoder did not start predicted frames with missing references but called the end of frame handling on them anyway. This caused an assertion in the VA API HW accelorator since it tried to render a picture with uninitialized buffers.	12 years ago
Diego Biurrun	2832ea26f3	Remove commented-out debug #define cruft	12 years ago
Diego Biurrun	bd8ac88214	avcodec: Add av_cold attributes to end functions missing them	12 years ago

Janne Grunau	757d85868b	vdpau: fix obsolete mpeg1 vdpau decoder when mpeg2 is disabled	12 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
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
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	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
Anton Khirnov	1d0feb5d1a	mpegvideo: split ff_draw_horiz_band(). Split out dependency on MpegEncContext.	12 years ago
Anton Khirnov	54974c6298	error_resilience: decouple ER from 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
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	0f583d20d5	mpeg12: fix the semantics of the int* parameter of decode() It is got_output, not data_size.	12 years ago
Anton Khirnov	d9a2e87b1c	mpeg12: move mpeg_decode_frame() lower Avoids a forward declaration of decode_chunks().	12 years ago

Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Gwenole Beauchesne	9cb150c9ab	hwaccel: mpeg2: decode first field, if requested. If user opted to present fields as they come, then the first field picture needs to be submitted to the HW for decoding. In particular, this fixes MPEG-2 decoding of interlaced streams. Tested on Intel Cedar Trail, Sandy Bridge and Ivy Bridge platforms. Someone reported on the ffmpeg-devel@ list this also works on DXVA (Windows) and other Linux platforms (NVIDIA, through the VA wrapper). This also means a similar patch to non-hwaccel VDPAU may be necessary. Note: I believe the SLICE_FLAG_ALLOW_FIELD is useless since the first field shall always be submitted to the HW anyway. Nobody uses HW accels (dxva, vaapi, vdpau, etc.) without that flag though.

Anton Khirnov	02beb9826b	lavc: deprecate AVCodecContext.sub_id. In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.	13 years ago
