Justin Ruggles	10e645e9cb	lavr: handle clipping in the float to s32 conversion We cannot clip to INT_MAX because that value cannot be exactly represented by a float value and ends up overflowing during conversion anyway. We need to use a slightly smaller float value, which ends up with slightly inaccurate results for samples which clip or nearly clip, but it is close enough. Using doubles as intermediates in the conversion would be more accurate, but it takes about twice as much time. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago

Anton Khirnov	e7ba5b1de0	lavr: change the type of the data buffers to uint8_t**. This is more consistent with what the rest of Libav does. This breaks API.	12 years ago
