Justin Ruggles 2e76f34387 flacenc: use RICE2 entropy coding mode for 24-bit 2012-11-05 15:32:30 -05:00
Justin Ruggles 13e1ee6c84 flacenc: add 24-bit encoding 2012-11-05 15:32:30 -05:00
Justin Ruggles 799e232490 flacdsp: move lpc encoding from FLAC encoder to FLACDSPContext 
Also, templatize the functions for 16-bit and 32-bit sample range. This will
be used for 24-bit FLAC encoding.

Justin Ruggles 5ff998a233 flacenc: use uint64_t for bit counts 
Needed to avoid integer overflows for 24-bit encoding.

Justin Ruggles 6a744d2619 flacenc: use a separate buffer for byte-swapping for MD5 checksum on big-endian 
This is much faster than calculating the MD5 one sample at a time.

Justin Ruggles 0366664ef9 lavc: check channel count after decoder init

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.
