type t

Internal state of a decoder.

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 -> Bytes.t -> 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 -> Bytes.t -> 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.
