Function opus_decoder_dred_decode_float 

pub unsafe extern "C" fn opus_decoder_dred_decode_float(
    st: *mut OpusDecoder,
    dred: *const OpusDRED,
    dred_offset: opus_int32,
    pcm: *mut f32,
    frame_size: opus_int32,
) -> c_int

Decode audio from an Opus DRED packet with floating point output.

Arguments

• st [in] - OpusDecoder*: Decoder state
• dred [in] - OpusDRED*: DRED state
• dred_offset [in] - opus_int32: position of the redundancy to decode (in samples before the beginning of the real audio data in the packet).
• pcm [out] - float*: Output signal (interleaved if 2 channels). length is frame_sizechannelssizeof(float)
• frame_size [in] - Number of samples per channel to decode in pcm. frame_size must be a multiple of 2.5 ms.

Returns

Number of decoded samples or [opus_errorcodes]
