Module Vorbis.Decoder

type t

Internal decoder state

Initialize decoder. Needs the first 3 packets of the ogg logical * stream. Use check_packet to check against the first one.

val info : t -> info

Get vorbis infos from the decoder

val comments : t -> string * (string * string) list

Get vorbis comments from the decoder

val check_packet : Ogg.Stream.packet -> bool

Check wether a ogg packet contains vorbis data. * Usefull for parsing ogg containers with multiple streams.

val decode_pcm : t -> Ogg.Stream.stream -> float array array -> int -> int -> int

decode_pcm dec stream buffer pos offset decodes pcm float data * from stream. The floats are written in buffer, starting at * position pos. The function returns the number of samples actually written.

val decode_pcm_ba : t -> Ogg.Stream.stream -> (float, Stdlib.Bigarray.float32_elt, Stdlib.Bigarray.c_layout) Stdlib.Bigarray.Array1.t array -> int -> int -> int

decode_pcm_ba dec stream buffer pos offset decodes pcm float data * from stream. The floats are written in buffer, starting at * position pos. The function returns the number of samples actually written.

val restart : t -> unit

Restart the decoder
