Rostislav Pehlivanov	67fa02ed79	opus_pvq: fix PVQ search for K < 5 and low Ns If the PVQ search picked a place to increment/decrement on the y[] vector which had no pulse then it would cause a desync since it would change the sum in the wrong direction. Fix this by not considering places without pulses as viable. This makes the PVQ search slightly worse at K < 5 which isn't all that common. Still, this is a workaround to prevent making broken files until I can think of a better way of fixing it. Also add an assertion, which can be removed or moved to assert1/2 once the PVQ search is stable. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
