Members

Member	Description
type	Int, decoding protocol.
left_stream_bytes	Int, remaining number of bytes to be decoded in the stream buffer, including those in the current frame that is being decoded.
left_stream_frames	Int, remaining number of frames to be decoded in the stream buffer, excluding those in the current frame that is being decoded. -1 indicates invalid. Valid only in frame mode.
left_decoded_frames	Int, number of remaining images in the buffer.
is_started	Int, whether the decoder has started to receive streams.
recv_stream_frames	Int, number of received stream frames in the stream buffer. -1 indicates invalid. Valid only in frame mode.
dec_stream_frames	Int, number of decoded frames in the stream buffer. Valid only in frame mode.
dec_err	Dictionary, decoding error information.
width	Int, width of the output image after decoding.
height	Int, height of the output image after decoding.
latest_frame_pts	PTS of the latest decoded image. Reserved.
