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
Ronald S. Bultje	5eec5a79da	jpeg: handle progressive in second field of interlaced. Progressive data is allocated later in decode_sof(), not allocating that data leads to NULL dereferences. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Reimar Döffinger	3b55429d56	Add and use av_fast_padded_malloc. The same as av_fast_malloc but uses av_mallocz and keeps extra always-0 padding. This does not mean the memory will be 0-initialized after each call, but actually only after each growth of the buffer. However this makes sure that a) all data anywhere in the buffer is always initialized b) the padding is always 0 c) the user does not have to bother with adding the padding themselves Fixes another valgrind warning about use of uninitialized data, this time with fate-vsynth1-jpegls.
