/** @defgroup opus_custom Opus Custom
|
||||
* @{
|
||||
* Opus Custom is an optional part of the Opus specification and
|
||||
* reference implementation which uses a distinct API from the regular
|
||||
* API and supports frame sizes that are not normally supported.\ Use
|
||||
* of Opus Custom is discouraged for all but very special applications
|
||||
* for which a frame size different from 2.5, 5, 10, or 20 ms is needed
|
||||
* (for either complexity or latency reasons) and where interoperability
|
||||
* is less important.
|
||||
*
|
||||
* In addition to the interoperability limitations the use of Opus custom
|
||||
* disables a substantial chunk of the codec and generally lowers the
|
||||
* quality available at a given bitrate. Normally when an application needs
|
||||
* a different frame size from the codec it should buffer to match the
|
||||
* sizes but this adds a small amount of delay which may be important
|
||||
* in some very low latency applications. Some transports (especially
|
||||
* constant rate RF transports) may also work best with frames of
|
||||
* particular durations.
|
||||
*
|
||||
* Libopus only supports custom modes if they are enabled at compile time.
|
||||
*
|
||||
* The Opus Custom API is similar to the regular API but the
|
||||
* @ref opus_encoder_create and @ref opus_decoder_create calls take
|
||||
* an additional mode parameter which is a structure produced by
|
||||
* a call to @ref opus_custom_mode_create. Both the encoder and decoder
|
||||
* must create a mode using the same sample rate (fs) and frame size
|
||||
* (frame size) so these parameters must either be signaled out of band
|
||||
* or fixed in a particular implementation.
|
||||
*
|
||||
* Similar to regular Opus the custom modes support on the fly frame size
|
||||
* switching, but the sizes available depend on the particular frame size in
|
||||
* use. For some initial frame sizes on a single on the fly size is available.

/** @defgroup opus_multistream Opus Multistream API
|
||||
* @{
|
||||
*
|
||||
* The multistream API allows individual Opus streams to be combined into a
|
||||
* single packet, enabling support for up to 255 channels. Unlike an
|
||||
* elementary Opus stream, the encoder and decoder must negotiate the channel
|
||||
* configuration before the decoder can successfully interpret the data in the
|
||||
* packets produced by the encoder. Some basic information, such as packet
|
||||
* duration, can be computed without any special negotiation.
|
||||
*
|
||||
* The format for multistream Opus packets is defined in
|
||||
* <a href="https://tools.ietf.org/html/rfc7845">RFC 7845</a>
|
||||
* and is based on the self-delimited Opus framing described in Appendix B of
|
||||
* <a href="https://tools.ietf.org/html/rfc6716">RFC 6716</a>.
|
||||
* Normal Opus packets are just a degenerate case of multistream Opus packets,
|
||||
* and can be encoded or decoded with the multistream API by setting
|
||||
* <code>streams</code> to <code>1</code> when initializing the encoder or
|
||||
* decoder.
|
||||
*
|
||||
* Multistream Opus streams can contain up to 255 elementary Opus streams.
|
||||
* These may be either "uncoupled" or "coupled", indicating that the decoder
|
||||
* is configured to decode them to either 1 or 2 channels, respectively.
|
||||
* The streams are ordered so that all coupled streams appear at the
|
||||
* beginning.
|
||||
*
|
||||
* A <code>mapping</code> table defines which decoded channel <code>i</code>
|
||||
* should be used for each input/output (I/O) channel <code>j</code>. This table is
|
||||
* typically provided as an unsigned char array.
|
||||
* Let <code>i = mapping[j]</code> be the index for I/O channel <code>j</code>.
|
||||
* If <code>i < 2*coupled_streams</code>, then I/O channel <code>j</code> is
|
||||
* encoded as the left channel of stream <code>(i/2)</code> if <code>i</code>
|
||||
* is even, or as the right channel of stream <code>(i/2)</code> if
|
||||
* <code>i</code> is odd. Otherwise, I/O channel <code>j</code> is encoded as
|
||||
* mono in stream <code>(i - coupled_streams)</code>, unless it has the special
|
||||
* value 255, in which case it is omitted from the encoding entirely (the
|
||||
* decoder will reproduce it as silence). Each value <code>i</code> must either
|
||||
* be the special value 255 or be less than <code>streams + coupled_streams</code>.
|
||||
*
|
||||
* The output channels specified by the encoder
|
||||
* should use the
|
||||
* <a href="https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-810004.3.9">Vorbis
|
||||
* channel ordering</a>. A decoder may wish to apply an additional permutation
|
||||
* to the mapping the encoder used to achieve a different output channel
|
||||
* order (e.g. for outputting in WAV order).
|
||||
*
|
||||
* Each multistream packet contains an Opus packet for each stream, and all of
|
||||
* the Opus packets in a single multistream packet must have the same
|
||||
* duration. Therefore the duration of a multistream packet can be extracted
|
||||
* from the TOC sequence of the first stream, which is located at the
|
||||
* beginning of the packet, just like an elementary Opus stream:
|
||||
*
|
||||
* @code
|
||||
* int nb_samples;
|
||||
* int nb_frames;
|
||||
* nb_frames = opus_packet_get_nb_frames(data, len);
|
||||
* if (nb_frames < 1)
|
||||
* return nb_frames;
|
||||
* nb_samples = opus_packet_get_samples_per_frame(data, 48000) * nb_frames;
|
||||
* @endcode
|
||||
*
|
||||
* The general encoding and decoding process proceeds exactly the same as in
|
||||
* the normal @ref opus_encoder and @ref opus_decoder APIs.
|
||||
* See their documentation for an overview of how to use the corresponding
|
||||
* multistream functions.
