Struct SwAudioEncoderOptions 

pub struct SwAudioEncoderOptions {
    pub codec: AudioCodec,
    pub sample_rate: u32,
    pub channels: u16,
    pub time_base: Rational,
    pub bit_rate: usize,
}

Construction-time options for SwAudioEncoder::new. sample_rate/ channels/time_base must already be known — same convention as crate::elements::SwEncoder’s own width/height/time_base — rather than inferred from the first frame, since avcodec_open2 needs them set before this can be opened at all. What’s actually fed to this element doesn’t have to match sample_rate/channels exactly — see SwAudioEncoder’s own docs on why.

Fields

codec: AudioCodec

Compressed audio codec to open.

sample_rate: u32

Encoder output sample rate, in hertz. A codec that accepts only certain rates rejects the rest at construction with SwAudioEncoderError::UnsupportedSampleRate — AudioCodec::Opus takes 48/24/16/12/8 kHz and nothing else, where AudioCodec::Aac takes any.

channels: u16

Encoder output channel count.

time_base: Rational

Must match the pts unit of whatever frames this receives — e.g. crate::elements::TestAudioSource::time_base/ crate::elements::AudioMixer::time_base.

bit_rate: usize

Target encoded bit rate, in bits per second.
