Struct FrameHeader 

pub struct FrameHeader {
    pub version: MpegVersion,
    pub bitrate_kbps: u16,
    pub sample_rate: u32,
    pub channel_mode: ChannelMode,
}

Layer III frame header fields.

The padding bit is not part of this struct: real Layer III streams flip it per frame (a bit-reservoir accounting detail owned by the encoder, not the container), so it is a parameter of FrameHeader::frame_len and Muxer::write_frame instead of a fixed per-session value.

Fields

version: MpegVersion

MPEG version.

bitrate_kbps: u16

Bitrate in kbps — must be one of the 14 standard values for version (Layer III).

sample_rate: u32

Sample rate — must be one of the 3 standard rates for version.

channel_mode: ChannelMode

Channel mode.

Implementations
