328b8bd7fc fixed a few trivial bugs: exporting celt_strerror(), changed DB_SCALING to a 
shift and removed the chec for DISABLE_STEREO in the mode creation.

30f7f813ea Changed all the celt*int*_t types to remove the _t suffix, which is reserved 
by POSIX. The other _t types that are not part of the API are still there
for now. Also, got rid of all that was left of the 64-bit types.

80ed147663 The number of channels is now set when creating the states rather than when 
creating the mode. This means that the same mode can be shared for mono and
stereo.

2dd3d3258a For celt_encoder_ctl CELT_SET_LTP is replaced with CELT_SET_PREDICTION 
which allows the caller to request that frames be independent.

1716999bbe Add paranoid checking for the validity of the encoder and the decoder 
state before using it. Handle malloc failures for the encoder and
decoder setup gracefully and without leaks.

9540077419 Documentation update: removed lookahead from the doxygen comment long after it 
was removed from celt_mode_create()

454d1d0c21 This code does a very naive reset of the state. It is possible (even likely) 
that I'm resetting more than is necessary, but I would have to know a lot
more about how CELT works to determine that.

98046cadcf Add a SET_LTP call to allow on the fly activation/deactivation of the long term 
predictor even in high complexity mode (LTP off is more loss robust), fix the
case where turning on LTP on a running stream can cause prediction against
bogus data by delaying the usage of the LTP until enough data has been encoded.

b6f9061343 celt_encoder_ctl() is a bit more type-safe. 2008-10-05 22:39:13 -04:00

8259531160 API: Change celt_encode and celt_encode_float so that they take an optional synthesis parameter after the PCM input. If optional_synthesis is null the encoder will be able to save some computation. If optional_synthesis is non-null if will be used to write the encoder's expectation of the decoder's output. Synthesis may alias the input pcm, so calling the encoder with the same buffer twice will achieve the old behavior. Remove 'restrict' from the CTL prototype. 2008-09-30 23:32:35 -04:00

a76a0b23eb Further simplified the API by passing the rate directly to the 
encode function. Also, trying to properly flush the bit packer
(still some problems left).
