Typedef Documentation
State of the decoder. One decoder state is needed for each stream. It is initialised once at the beginning of the stream. Do *not* re-initialise the state for every frame
Definition at line 80 of file celt.h.
Encoder state.
Contains the state of an encoder. One encoder state is needed for each stream. It is initialised once at the beginning of the stream. Do *not* re-initialise the state for every frame.
Definition at line 75 of file celt.h.
The mode contains all the information necessary to create an encoder. Both the encoder and decoder need to be initialised with exactly the same mode, otherwise the quality will be very bad
Definition at line 85 of file celt.h.
