vp9: fix crash if segmentation=1, keyframe/intraonly=1 and updatemap=0. · acafbb4d

Ronald S. Bultje authored Dec 24, 2013

The reference map is never used in such cases, but we accidently copied
it anyway. This could cause crashes if this map has not yet been
allocated. Fixes trac ticket 3188.

This should make discontinuity detection more robust and detect

timestamps before can be missing

VC1: Fix intensity compensation performance regression · ed5bed41

Mason Carter authored Dec 22, 2013

Fix https://trac.ffmpeg.org/ticket/3204

The problem was that intensity compensation was always used once it was
encountered. This is because v->next_use_ic was never set back to zero.
To fix this, when resetting v->next_luty/uv, also reset v->next_use_ic.

This improved (restored) performance by 85% when decoding
