Struct DecodedFrame 

pub struct DecodedFrame {
    pub envelope: FrameEnvelope,
    pub decode_event: Option<CUevent>,
    pub event_return: Option<Sender<CUevent>>,
}

A decoded NV12 frame with an optional CUDA event for cross-stream sync.

When produced by a real hardware decoder (NVDEC), decode_event carries the event recorded on decode_stream after the D2D copy. The preprocess stage calls cuStreamWaitEvent(preprocess_stream, event) before reading the texture — this ensures the decode data is ready without CPU-blocking.

Mock decoders set both fields to None.

Fields

envelope: FrameEnvelope

decode_event: Option<CUevent>

CUDA event recorded after decode completes. None for mock decoders.

event_return: Option<Sender<CUevent>>

Channel to return used events to the decoder’s EventPool for reuse.
