Queue
class QueueFull(message: String, val frame: DataTrackFrame, cause: Throwable? = null) : DataTrackPushFrameException
The send queue is full; the frame was not enqueued.
The rejected frame — the same instance that was pushed, not a copy — comes back so it can be retried or re-queued. Mainly for LocalDataTrack.send, where frames come from a kotlinx.coroutines.flow.Flow and the caller holds no reference of its own.
