Anton Khirnov	8ad3267ce3	oggdec: do not fall back on binary search in the generic code. Binary search is already attempted in the format-specific seek function, so the fallback is only reached if binary search failed already.	12 years ago

Loren Merritt	c93ccf5a4c	lpc: use levinson for the first pass of multipass cholesky Levinson is faster, and cholesky is only needed if we want to apply different weights to different samples, which doesn't happen on the first pass. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
