Members

Member	Description
type	Decode protocol.
left_stream_bytes	Number of bytes in the stream buffer to be decoded, including the number of bytes that are not decoded yet in the current frame in the decode progress.
left_stream_frames	Number of frames in the stream buffer to be decoded, excluding the current frame in the decode progress. –1 indicates invalid. It is valid only when the streams are sent by frame.
left_decoded_frames	Number of remaining images in the image buffer.
is_started	Whether the decoder has started to receive a stream.
recv_stream_frames	Number of received frames in the stream buffer. –1 indicates invalid. It is valid only when the streams are sent by frame.
dec_stream_frames	Number of decoded frames in the stream buffer. Valid only in frame mode.
dec_err	Decode error.
width	Image width of the decode output.
height	Image height of the decode output.
latest_frame_pts	PTS of the latest decoded image. Reserved.
