val check : Ogg.Stream.packet -> bool* Check wether an ogg logical stream contains theora data * * This function shall be called just after you put * the first page in the stream. See examples/thdecode.ml * * Raises Ogg.Bad_data if the stream does not contain theora data.
val create : unit -> decoderInitialize the decoding structure. * The decoder should then be processed with headerin.
val headerin :
decoder ->
Ogg.Stream.packet ->
t * info * string * (string * string) listAdd one packet from the stream and try to parse theora headers. * * Returns an initialized decoder. * * Raises Ogg.Not_enough_data is decoding header needs another packet. * * This function should be called with the first packets of the stream * until it returns the requested values. It may consume at most 5 packets * (3 header packet, 1 additional packet and the initial video packet)
val get_yuv : t -> Ogg.Stream.stream -> yuv_buffer* Output the next available frame of decoded YUV data. * * Raises Ogg.Not_enough_data if the Ogg.Stream.stream which * has been used to initialize the handler does not contain * enought data. You should submit a new page to it, and * run this function again until it returns. * * Raises Not_initialized if the decoder was not properly * initialized with headerin.
val frames_of_granulepos : t -> Stdlib.Int64.t -> Stdlib.Int64.tConvert a granulepos to an absolute frame index, starting at 0. * The granulepos is interpreted in the context of a given theora_state handle.
