Ronald S. Bultje	c2871568cf	vp9: fix invalid ref frame w/h on size change. Fixes invalid reads and crashes in vp90-2-05-resize.webm and fuzzed6.ivf. The output is still not identical to what libvpx does (because we don't actually scale in MC). Reviewed-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	d9343c3484	vp9: disable use_last_frame_mvs on resolution change (scalable). Prevents some invalid memory accesses after resolution change in vp90-2-05-resize.webm, and libvpx does this too. Reviewed-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Ronald S. Bultje	4147b337c1	vp9: fix memory corruption if header decoding fails after size change.	11 years ago
Ronald S. Bultje	c9e6325ed9	vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.	11 years ago
