type t

Internal state of a decoder.

exception Error of int

An error occured...

exception Failed

val error_message : int -> string

Get the error message corresponding to a raised Error.

val min_bytes_per_channel : int

A decode call can eat up to min_bytes_per_channel bytes per decoded channel, so at least so much bytes per channel should be available in this stream.

val create : unit -> t

val init : t -> string -> int -> int -> int * int * int

init dec buf ofs len initializes a decoder given the len bytes of data in buf starting at offset ofs. It returns the offset (number of bytes to skip), the samplerate and the number of channels of the stream. This function should be used for AAC data.

val decode : t -> string -> int -> int -> int * float array array

decode dec buf ofs len decodes at most len bytes of data in buf starting at offset ofs. It returns the number of bytes actually decoded and the decoded data (non-interleaved).

val post_sync_reset : t -> unit

val find_frame : string -> int

Heuristic guess of the offset of the begining of a frame.
