Struct QosMessage 

pub struct QosMessage {
    pub jitter_ns: i64,
    pub running_time_ns: u64,
}

Downstream-originated quality-of-service signal: a synchronising sink is running behind the pipeline clock and dropped a late frame. Travels upstream along a link’s reverse channel and is surfaced to the producing element as a PushOutcome::Qos, so a source / decoder can shed load (skip frames) to let the pipeline catch up. The GStreamer QoS event analog (the BusMessage::Qos report is the out-of-band sibling the application observes).

Fields

jitter_ns: i64

How far past its deadline the dropped frame was, ns. Positive is late (behind the clock); the producer skips roughly this much stream time to catch up.

running_time_ns: u64

Running time (PTS) of the late frame, for reference.
