Variants

FrameDecoded(DqBuffer<Capture, P::HandleType>)

Emitted when a frame is decoded.

The parameter is the dequeued buffer, containing the plane handles of the decoded frame as well as its V4L2 parameters such as flags. The flags remain untouched, but the client should not take action on some of them: for instance, when the V4L2_BUF_FLAG_LAST is set, the proper corresponding event (resolution change or end of stream) will be signaled appropriately.

EndOfStream

Emitted when a previously requested drain request completes.

When this event is emitted, the client knows that all the frames corresponding to all the input buffers queued before the drain request have been emitted.
