- *
- * The Opus codec is designed for interactive speech and audio transmission over the Internet.
- * It is designed by the IETF Codec Working Group and incorporates technology from
- * Skype's SILK codec and Xiph.Org's CELT codec.
- *
- * The Opus codec is designed to handle a wide range of interactive audio applications,
- * including Voice over IP, videoconferencing, in-game chat, and even remote live music
- * performances. It can scale from low bit-rate narrowband speech to very high quality
- * stereo music. Its main features are:
-
- * @li Sampling rates from 8 to 48 kHz
- * @li Bit-rates from 6 kb/s to 510 kb/s
- * @li Support for both constant bit-rate (CBR) and variable bit-rate (VBR)
- * @li Audio bandwidth from narrowband to full-band
- * @li Support for speech and music
- * @li Support for mono and stereo
- * @li Support for multichannel (up to 255 channels)
- * @li Frame sizes from 2.5 ms to 60 ms
- * @li Good loss robustness and packet loss concealment (PLC)
- * @li Floating point and fixed-point implementation
- *

- * @{
- *
- * @brief This page describes the process and functions used to encode Opus.
- *
- * Since Opus is a stateful codec, the encoding process starts with creating an encoder
- * state. This can be done with:
- *
- * @code
- * int error;
- * OpusEncoder *enc;
- * enc = opus_encoder_create(Fs, channels, application, &error);
- * @endcode
- *
- * From this point, @c enc can be used for encoding an audio stream. An encoder state
- * @b must @b not be used for more than one stream at the same time. Similarly, the encoder
- * state @b must @b not be re-initialized for each frame.
- *
- * While opus_encoder_create() allocates memory for the state, it's also possible
- * to initialize pre-allocated memory:
- *
- * @code
- * int size;
- * int error;
- * OpusEncoder *enc;
- * size = opus_encoder_get_size(channels);
- * enc = malloc(size);
- * error = opus_encoder_init(enc, Fs, channels, application);
- * @endcode
- *
- * where opus_encoder_get_size() returns the required size for the encoder state. Note that
- * future versions of this code may change the size, so no assuptions should be made about it.
- *
- * The encoder state is always continuous in memory and only a shallow copy is sufficient
- * to copy it (e.g. memcpy())
- *
- * It is possible to change some of the encoder's settings using the opus_encoder_ctl()
- * interface. All these settings already default to the recommended value, so they should
- * only be changed when necessary. The most common settings one may want to change are:
- *
- * @code
- * opus_encoder_ctl(enc, OPUS_SET_BITRATE(bitrate));
- * opus_encoder_ctl(enc, OPUS_SET_COMPLEXITY(complexity));
- * opus_encoder_ctl(enc, OPUS_SET_SIGNAL(signal_type));
- * @endcode
- *
- * where
- *
- * @arg bitrate is in bits per second (b/s)
- * @arg complexity is a value from 1 to 10, where 1 is the lowest complexity and 10 is the highest
- * @arg signal_type is either OPUS_AUTO (default), OPUS_SIGNAL_VOICE, or OPUS_SIGNAL_MUSIC
- *
- * See @ref opus_encoderctls and @ref opus_genericctls for a complete list of parameters that can be set or queried. Most parameters can be set or changed at any time during a stream.
- *
- * To encode a frame, opus_encode() or opus_encode_float() must be called with exactly one frame (2.5, 5, 10, 20, 40 or 60 ms) of audio data:
- * @code
- * len = opus_encode(enc, audio_frame, frame_size, packet, max_packet);
- * @endcode
- *
- * where
- * <ul>
- * <li>audio_frame is the audio data in opus_int16 (or float for opus_encode_float())</li>
- * <li>frame_size is the duration of the frame in samples (per channel)</li>
- * <li>packet is the byte array to which the compressed data is written</li>
- * <li>max_packet is the maximum number of bytes that can be written in the packet (4000 bytes is recommended).
- * Do not use max_packet to control VBR target bitrate, instead use the #OPUS_SET_BITRATE CTL.</li>
- * </ul>
- *
- * opus_encode() and opus_encode_float() return the number of bytes actually written to the packet.
- * The return value <b>can be negative</b>, which indicates that an error has occurred. If the return value
- * is 2 bytes or less, then the packet does not need to be transmitted (DTX).
- *
- * Once the encoder state if no longer needed, it can be destroyed with
- *
- * @code
- * opus_encoder_destroy(enc);
- * @endcode
- *
- * If the encoder was created with opus_encoder_init() rather than opus_encoder_create(),
- * then no action is required aside from potentially freeing the memory that was manually
- * allocated for it (calling free(enc) for the example above)
- *

- * dec = opus_decoder_create(Fs, channels, &error);

- * @li error will hold the error code in case of failure (or #OPUS_OK on success)
- * @li the return value is a newly created decoder state to be used for decoding
- *
- * While opus_decoder_create() allocates memory for the state, it's also possible
- * to initialize pre-allocated memory:
- * @code
- * int size;
- * int error;
- * OpusDecoder *dec;
- * size = opus_decoder_get_size(channels);

- * @endcode
- * where opus_decoder_get_size() returns the required size for the decoder state. Note that

- *
- * The decoder state is always continuous in memory and only a shallow copy is sufficient
- * to copy it (e.g. memcpy())
- *
- * To decode a frame, opus_decode() or opus_decode_float() must be called with a packet of compressed audio data:
- * @code
- * frame_size = opus_decode(dec, packet, len, decoded, max_size, 0);
- * @endcode
- * where
- *
- * @li packet is the byte array containing the compressed data
- * @li len is the exact number of bytes contained in the packet
- * @li decoded is the decoded audio data in opus_int16 (or float for opus_decode_float())
- * @li max_size is the max duration of the frame in samples (per channel) that can fit into the decoded_frame array
- *
- * opus_decode() and opus_decode_float() return the number of samples (per channel) decoded from the packet.
- * If that value is negative, then an error has occurred. This can occur if the packet is corrupted or if the audio
- * buffer is too small to hold the decoded audio.
- *
- * Opus is a stateful codec with overlapping blocks and as a result Opus
- * packets are not coded independently of each other. Packets must be
- * passed into the decoder serially and in the correct order for a correct
- * decode. Lost packets can be replaced with loss concealment by calling
- * the decoder with a null pointer and zero length for the missing packet.
- *
- * A single codec state may only be accessed from a single thread at

- * @{
- *
- * The repacketizer can be used to merge multiple Opus packets into a single
- * packet or alternatively to split Opus packets that have previously been
- * merged. Splitting valid Opus packets is always guaranteed to succeed,
- * whereas merging valid packets only succeeds if all frames have the same
- * mode, bandwidth, and frame size, and when the total duration of the merged
- * packet is no more than 120 ms. The 120 ms limit comes from the
- * specification and limits decoder memory requirements at a point where
- * framing overhead becomes negligible.
- *
- * The repacketizer currently only operates on elementary Opus
- * streams. It will not manipualte multistream packets successfully, except in
- * the degenerate case where they consist of data from a single stream.
- *
- * The repacketizing process starts with creating a repacketizer state, either
- * by calling opus_repacketizer_create() or by allocating the memory yourself,
- * e.g.,
- * @code
- * OpusRepacketizer *rp;
- * rp = (OpusRepacketizer*)malloc(opus_repacketizer_get_size());
- * if (rp != NULL)
- * opus_repacketizer_init(rp);
- * @endcode
- *
- * Then the application should submit packets with opus_repacketizer_cat(),
- * extract new packets with opus_repacketizer_out() or
- * opus_repacketizer_out_range(), and then reset the state for the next set of
- * input packets via opus_repacketizer_init().
- *
- * For example, to split a sequence of packets into individual frames:
- * @code
- * unsigned char *data;
- * int len;
- * while (get_next_packet(&data, &len))
- * {
- * unsigned char out[1276];
- * opus_int32 out_len;
- * int nb_frames;
- * int err;
- * int i;
- * err = opus_repacketizer_cat(rp, data, len);
- * if (err != OPUS_OK)
- * {
- * release_packet(data);
- * return err;
- * }
- * nb_frames = opus_repacketizer_get_nb_frames(rp);
- * for (i = 0; i < nb_frames; i++)
- * {
- * out_len = opus_repacketizer_out_range(rp, i, i+1, out, sizeof(out));
- * if (out_len < 0)
- * {
- * release_packet(data);
- * return (int)out_len;
- * }
- * output_next_packet(out, out_len);
- * }
- * opus_repacketizer_init(rp);
- * release_packet(data);
- * }
- * @endcode
- *
- * Alternatively, to combine a sequence of frames into packets that each
- * contain up to <code>TARGET_DURATION_MS</code> milliseconds of data:
- * @code
- * // The maximum number of packets with duration TARGET_DURATION_MS occurs
- * // when the frame size is 2.5 ms, for a total of (TARGET_DURATION_MS*2/5)
- * // packets.
- * unsigned char *data[(TARGET_DURATION_MS*2/5)+1];
- * opus_int32 len[(TARGET_DURATION_MS*2/5)+1];
- * int nb_packets;
- * unsigned char out[1277*(TARGET_DURATION_MS*2/2)];
- * opus_int32 out_len;
- * int prev_toc;
- * nb_packets = 0;
- * while (get_next_packet(data+nb_packets, len+nb_packets))
- * {
- * int nb_frames;
- * int err;
- * nb_frames = opus_packet_get_nb_frames(data[nb_packets], len[nb_packets]);
- * if (nb_frames < 1)
- * {
- * release_packets(data, nb_packets+1);
- * return nb_frames;
- * }
- * nb_frames += opus_repacketizer_get_nb_frames(rp);
- * // If adding the next packet would exceed our target, or it has an
- * // incompatible TOC sequence, output the packets we already have before
- * // submitting it.
- * // N.B., The nb_packets > 0 check ensures we've submitted at least one
- * // packet since the last call to opus_repacketizer_init(). Otherwise a
- * // single packet longer than TARGET_DURATION_MS would cause us to try to
- * // output an (invalid) empty packet. It also ensures that prev_toc has
- * // been set to a valid value. Additionally, len[nb_packets] > 0 is
- * // guaranteed by the call to opus_packet_get_nb_frames() above, so the
- * // reference to data[nb_packets][0] should be valid.
- * if (nb_packets > 0 && (
- * ((prev_toc & 0xFC) != (data[nb_packets][0] & 0xFC)) ||
- * opus_packet_get_samples_per_frame(data[nb_packets], 48000)*nb_frames >
- * TARGET_DURATION_MS*48))
- * {

-/** @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 outputing 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.
