Expand description

Events reported by the VideoDecoderBackendSession::next_event method.

Variants§

§

StreamFormatChanged

Sent whenever the format of the stream has changed. The new format can be read using VideoDecoderBackendSession::current_format.

§

InputBufferDone

Sent whenever an OUTPUT buffer is done processing and can be reused.

Fields

§buffer_id: u32
§error: i32

If error != 0, indicate the error flag on the corresponding v4l2_buffer

§

FrameCompleted

Sent whenever a decoded frame is ready on the CAPTURE queue.

Fields

§buffer_id: u32
§timestamp: timeval
§bytes_used: Vec<u32>
§is_last: bool
