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
