Michael Niedermayer	aa000ddab2	avcodec/svq3: add scaling matrix init that was removed from h264 init This is needed for svq3 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	e6c710600e	avcodec/svq3: add initialization which was removed from h264 init This is needed for the svq3 code to work Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Anton Khirnov	249796e256	svq3: initialize some required H264Context fields. They are no longer initialized in ff_h264_decode_init() since `43fd3dd`, so svq3 needs to initialize the manually. Fixes svq3 decoding, broken since `43fd3dd`.	10 years ago
Anton Khirnov	c28ed1d743	h264: move [uv]linesize to the per-slice context While it is a per-frame variable, it is only really used in the low-level decoding code, so it is more efficient to store it in the slice context.	10 years ago
Anton Khirnov	36d04801ba	h264: move the scratch buffers into the per-slice context Also change the method for allocating them. Instead of two possible alloc calls from different places, just ensure they are allocated at the start of each slice. This should be simpler and less bug-prone than the previous method.	10 years ago

Michael Niedermayer	075a165d27	avcodec/svq3: Dont memcpy AVFrame This avoids out of array accesses Fixes: asan_heap-uaf_21f42e4_9_asan_heap-uaf_21f42e4_278_gl2.mov Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Diego Biurrun	54b2ce7418	mpeg: Drop unused parameters from ff_draw_horiz_band()	11 years ago
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	c5f7c8f9a9	avcodec/svq3: set last/next frames to defaults before use Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago

Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Martin Storsjö	601c2015bc	svq3: Avoid a division by zero If the height is zero, the decompression will probably end up failing due to not fitting into the allocated buffer later anyway, so this doesn't need any more elaborate check.
