Functions

val create : parameters -> t

Create a new encoder.

val recommended_minimum_input : t -> int

Recommended minimun input to feed to the decoder.

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

encode_string enc data encodes the given S16LE pcm buffer and returns AAC data and the number of input bytes consumed by the decoder.

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

encode_substring enc data offset len encodes the sub-string of data starting at position offset and of length len. Raises Invalid_argument if such sub-string does not exist.

val encode_buffer : t -> Stdlib.Buffer.t -> string

encode_buffer enc buffer encodes S16LE data from the string buffer buffer and drops consumed data from buffer. This does nothing if Buffer.length buffer < recommended_minumun_input enc
