Ronald S. Bultje	29045fbfd4	vp9: clip motion vectors in the same way as libvpx does. The practical effect of this is that the scaling will wrongly not be applied to the interpolation edge (the 3/4 constants in this patch). In other words, we clip to the pre-scaling interpolation, even though these should be clipped post-scaling. The resulting out-of-frame MVs are thus automatically clipped within the visible portion of the frame, which is probably not the intention, but is unfortunately what libvpx does, so we need to copy that behaviour.	10 years ago
Ronald S. Bultje	96a58a8daa	vp9: set skip flag if the block had no coded coefficients. This reproduces libvpx behaviour. It seems like it originally only targeted loopfilter behaviour, but this unfortunately effects following block contexting and thus directs bitstream sync.	10 years ago

Ronald S. Bultje	d32d0593f1	vp9: disable more pmulhrsw optimizations in idct16/32. For idct16, only when called from a adst16x16 variant, so impact is minor. For idct32, for all, so relatively major impact.	10 years ago
Ronald S. Bultje	96d30c3495	vp9: disable all pmulhrsw in 8/16 iadst x86 optimizations. They all overflow in various samples that are considered valid input.	10 years ago

wm4	b697b297b7	id3v2: do not export APIC description if empty APIC tags always have a description. Tag writers obviously leave it empty if there is no description.
