Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago

Michael Niedermayer	0766b6e3ec	rv20: fix lowres out of array read Fixes Ticket1239 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`. Conflicts: cmdutils.c libavcodec/arm/vp8dsp_init_arm.c libavcodec/mpegvideo.c libavcodec/mpegvideo.h libavutil/arm/Makefile 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
Reimar Döffinger	438f3ef821	RV20: try keeping aspect during resolution changes. Resolution changes are usually only used to scale with network bandwidth, the (full) resolution specified in the RM header really is authoritative. While I am not sure this is the best solution, it is a conservative approach that still should fix the most common cases. In particular, it fixes aspect with the sample from trac issue #785 (in MPlayer, ffplay seems to just ignore sample aspect changes in mid-playback).

Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations 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>	13 years ago
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
