* mpeg1: Make intra-block decoding independent of MpegEncContextVittorio Giovara2016-02-09
| | | | | | | This allows untangling the eatqi decoder from the MPEG-1 decoder. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>

* Remove a number of unnecessary dsputil.h #includesDiego Biurrun2014-04-04
|
* Deprecate obsolete XvMC hardware decoding supportDiego Biurrun2013-11-13
| | | | | | | XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it.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.

* lavc: Rename avpriv_mpv_find_start_code after moving out from mpegvideoMartin Storsjö2013-03-26
| | | | | | | 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>
* mpeg12: do not fail on zero dimensions in the sequence header.Anton Khirnov2013-03-18
| | | | | | | | | | | | 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.
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08

* Add missing error_resilience includes to files that use ERDiego Biurrun2013-03-07

* lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecsRonald S. Bultje2013-03-06
| | | | | | | | | 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>
* mpegvideo: split ff_draw_horiz_band().Anton Khirnov2013-02-15
| | | | Split out dependency on MpegEncContext.
* error_resilience: decouple ER from MpegEncContextAnton Khirnov2013-02-15
|
* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* mpeg12: do not decode extradata more than once.Anton Khirnov2012-12-19
| | | | | | Fixes CVE-2012-2803. CC: libav-stable@libav.org
* mpegvideo: allocate scratch buffers after linesize is knownJanne Grunau2012-12-18
| | | | | | | | | | | 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.
* avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tabMartin Storsjö2012-10-18
| | | | | | | 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>

* mpeg12: fix the semantics of the int* parameter of decode()Anton Khirnov2012-09-29
| | | | It is got_output, not data_size.
* mpeg12: move mpeg_decode_frame() lowerAnton Khirnov2012-09-29
| | | | Avoids a forward declaration of decode_chunks().

* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* hwaccel: mpeg2: decode first field, if requested.Gwenole Beauchesne2012-04-08
| | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com> Signed-off-by: Martin Storsjö <martin@martin.st>
* cosmetics: Align codec declarationsMartin Storsjö2012-04-06

* lavc: deprecate AVCodecContext.sub_id.Anton Khirnov2012-03-04
| | | | | | | 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.

* mpegenc: use avctx->slices as number of slicesJanne Grunau2012-01-02
| | | | | | Adds a new member to MpegEncContext to hold the number of used slice contexts. Fixes segfaults with '-threads 17 -thread_type slice' and fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.
* error_resilience: use the ER_ namespaceLuca Barbato2011-12-13

* mpeg12: fix mpeg_decode_slice context parameter typeJanne Grunau2011-10-24
| | | | | | During slice threading only MpegEncContext is passed to mpeg_decode_slice, remove a wrong cast and change the function definition to take MpegEncContext pointer.
* Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context"Janne Grunau2011-10-24
| | | | | | | | This reverts commit da22ba7df461c13bf0b0eabc953303803a285d91 since it broke slice threading. Slice threading just duplicates MpegEncContext so every value used during mpeg_decode_slice has to be in it. A second patch will fix the illusion that Mpeg1Context is available in mpeg_decode_slice.
* mpeg12: move closed_gop from MpegEncContext to Mpeg1ContextAnton Khirnov2011-10-23
| | | | It's MPEG-1/2 specific.
* mpeg12: move full_pel from MpegEncContext to Mpeg1ContextAnton Khirnov2011-10-23

* mpeg12: move Mpeg1Context from mpeg12.c to mpeg12.hAnton Khirnov2011-10-23
