Justin Ruggles a1f4cd371a atrac3: replace a calculation with FFALIGN() 
This allocates 4 bytes less than the previous code if avctx->block_align is
a multiple of 4, but the extra 4 bytes is not really needed.

Justin Ruggles 46a86c6194 alacdec: set bits_per_raw_sample 2012-10-21 23:54:51 -04:00
Justin Ruggles abd8b9e7e0 libmp3lame: resize the output buffer if needed 
The LAME API documentation for the required buffer size refers to the size for
a single encode call. However, we store multiple frames in the same output
buffer but only read 1 frame at a time out of it. As a result, the buffer size
given in lame_encode_buffer() is actually smaller than what it should be.
Since we do not know how many frames it will end up buffering, it is best to
just reallocate if needed.

Justin RugglesandLuca Barbato 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.
