Rostislav Pehlivanov	f41e37b84f	dirac_vlc: prevent shifting a 0 by 64 bits when zeroing residue Adding a check for bits == 0 would still make Coverity misdetect this, so just revert to the normal way of setting the residue to 0. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
Rostislav Pehlivanov	c4adcff976	dirac_vlc: add a SET_RESIDUE macro and fix recent regression Can also be used in future cleanups since 99% of the time the leftover appending will just append to an already empty residue. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Rostislav Pehlivanov	e24c31b656	dirac_vlc: fix undefined shifts Shifting by more than 63 bits is undefined behavior, athough any compiler not returning 0 after shifting by any amount would be insane.

Rostislav Pehlivanov	0eb0f93109	diracdec: implement a LUT-based Golomb code parser Still much left to optimize, but it provides a significant performance improvement - 10% for 300Mbps (1080p30), 25% for 1.5Gbps (4k 60fps) in comparison with the default implementation.
