val init : Ogg.Stream.packet ->

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

val info : t -> Vorbis.info

Get vorbis infos from the decoder

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

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
