Members

Member	Description
type	Decoding protocol. For details, see hi_payload_type.
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. For details, see hi_vdec_dec_err.
width	Image width of the decode output.
height	Image height of the decode output.
latest_frame_pts	PTS of the latest decoded image. Reserved parameter, not supported currently.
