Typedef Documentation

typedef struct daala_dec_ctx daala_dec_ctx

The decoder context.

typedef struct daala_setup_info daala_setup_info

Setup information.

This contains auxiliary information decoded from the setup header by daala_decode_header_in() to be passed to daala_decode_alloc(). It can be re-used to initialize any number of decoders, and can be freed via daala_setup_free() at any time.
