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

Alex Converse	2f6528537f	rv10/20: Fix a buffer overread caused by losing track of the remaining buffer size. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Kostya Shishkov	331971116d	rv10/20: tell decoder to use edge emulation This removes out-of-edge motion compensation artifacts (easily spotted green blocks in avplay, gray blocks in transcoding), for example here: http://samples.libav.org/samples/real/tv_watching_t1.rm Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Kostya Shishkov	9791c02733	Saner RV1/2 initialisation and RV2 header parsing. Old version was based on lots of guesswork which had different hacks based on 32-bit version field instead of splitting it into major/minor/micro version. RV2 picture header parser also had a few places where it deviated from binary decoder. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
