Function opus_dred_parse

pub unsafe extern "C" fn opus_dred_parse(
    dred_dec: *mut OpusDREDDecoder,
    dred: *mut OpusDRED,
    data: *const c_uchar,
    len: opus_int32,
    max_dred_samples: opus_int32,
    sampling_rate: opus_int32,
    dred_end: *mut c_int,
    defer_processing: c_int,
) -> c_int

Decode an Opus DRED packet.

Arguments

• dred_dec [in] - OpusDRED*: DRED Decoder state
• dred [in] - OpusDRED*: DRED state
• data [in] - char*: Input payload
• len [in] - opus_int32: Number of bytes in payload
• max_dred_samples [in] - opus_int32: Maximum number of DRED samples that may be needed (if available in the packet).
• sampling_rate [in] - opus_int32: Sampling rate used for max_dred_samples argument. Needs not match the actual sampling rate of the decoder.
• dred_end [out] - opus_int32*: Number of non-encoded (silence) samples between the DRED timestamp and the last DRED sample.
• defer_processing [in] - int: Flag (0 or 1). If set to one, the CPU-intensive part of the DRED decoding is deferred until opus_dred_process() is called.

Returns

Offset (positive) of the first decoded DRED samples, zero if no DRED is present, or [opus_errorcodes]
