Struct PrimaryStream 

pub struct PrimaryStream {
    pub demux: &'static str,
    pub props: Vec<(String, String)>,
    pub caps: Caps,
}

The single-stream demux + decode chain a bare (non-fan-out) decodebin should build for a file-backed container whose default single-stream demux guesses the wrong port (M746). A single-stream demuxer fixes its output pad at negotiation before parsing any byte, so it defaults to a video port; an audio-only MPEG-TS then auto-plugs a video decoder and fails “no caps overlap”. expand_decodebin consults a hook so the demux instead selects the container’s real (audio) stream, building filesrc ! demux stream=X ! <decoder> ! ....

Fields

demux: &'static str

The single-stream demux element to plug (e.g. "tsdemux").

props: Vec<(String, String)>

Properties that select the primary stream on demux (e.g. [("stream", "aac")]).

caps: Caps

The elementary caps the demux emits for that stream, the auto-plug input for the decoder chain spliced after it.
