Michael Niedermayer	bf5386385d	mpeg12: switch to av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	5e50a5724b	Revert "removing lowres support" There have been multiple user complaints about loosing this feature while its not clear the 3% speedloss claims where real or fabricated. My own testing indicates no statistically significant speed difference both with mpeg2 and mpeg4, and if at all the code with lowres support is a tiny bit faster than without. This reverts commit `92ef4be4ab`, reversing changes made to `2e07f42957`.

Michael Niedermayer	951cbea56f	mpeg12dec: reset data size after parsing extradata. This ended up corrupting data structures and may possibly lead to a double free. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 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

Janne Grunau	d99fe3a478	mpeg12: fix mpeg_decode_slice context parameter type During slice threading only MpegEncContext is passed to mpeg_decode_slice, remove a wrong cast and change the function definition to take MpegEncContext pointer.	13 years ago
Michael Niedermayer	fe906830fd	Revert "mpeg12: move closed_gop from MpegEncContext to Mpeg1Context" This reverts commit `3fc0830432`. The revert is done because the reasoning behind the commit was flawed, closed_gop is not mpeg1/2 specific. Conflicts: libavcodec/mpeg12.c libavcodec/mpeg12.h	13 years ago
Janne Grunau	cd8c64e197	Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context" This reverts commit `da22ba7df4` 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.	13 years ago
