* 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>
* Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov2012-10-08

* 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().
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07

* 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
| | | | | | | Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
* mpeg12: Do not change frame_pred_frame_dct flag and demote error into a warningAnne Aaron2012-04-06
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* 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.
