Enum PlayerCommand 

pub enum PlayerCommand {
    Play,
    Pause,
    Stop,
    Seek(Duration),
    SetRate(f64),
    SetAvOffset(i64),
    UpdateLayout(Box<Timeline>),
}

Commands sent from PlayerHandle to PlayerRunner via a bounded sync channel (capacity 64).

Variants

Play

Resume playback (clear the paused flag).

Pause

Pause playback.

Stop

Stop the presentation loop; PlayerRunner::run returns after the current frame.

Seek(Duration)

Seek to pts. Consecutive seeks are coalesced — only the last one executes.

SetRate(f64)

Set the playback rate. Values ≤ 0.0 are ignored.

SetAvOffset(i64)

Set the A/V offset in milliseconds. Clamped to ±5 000 ms.

UpdateLayout(Box<Timeline>)

Replace the timeline clip layout without stopping playback.

Handled only by TimelineRunner; PlayerRunner ignores it. The runner updates its internal ClipState / AudioOnlyTrack positions in place and seeks to the last known media PTS so the next frame is spatially correct after the layout change.
