Description

Defines the stream information.

Atlas 350 Accelerator Card does not support this structure.

Atlas A3 training product/Atlas A3 inference product does not support this structure.

Atlas A2 training product/Atlas A2 inference product does not support this structure.

For the Atlas inference product, this structure is reserved and is not supported currently.

Members

Member	Description
ref_type	Type of the frame in advanced frame skipping reference mode. The Atlas 200I/500 A2 inference product does not support this parameter.
pic_bytes	Number of bytes in the encoded stream.
pic_cnt	Number of frames if is_by_frame == 1; or number of packets if is_by_frame == 0. The Atlas 200I/500 A2 inference product does not support this parameter.
start_qp	Start QP value of the frame to be encoded.
mean_qp	Average QP value of the encoded frame.
is_p_skip	Whether the P-frame is coded as a skip frame. The Atlas 200I/500 A2 inference product does not support this parameter.
residual_bits	Number of residual bits in the current frame. The Atlas 200I/500 A2 inference product does not support this parameter.
head_bits	Number of header bits in the current frame. The Atlas 200I/500 A2 inference product does not support this parameter.
madi_val	MADi value of the spatial texture complexity of the current frame. The Atlas 200I/500 A2 inference product does not support this parameter.
madp_val	MADp value of the temporal motion complexity of the current frame. The Atlas 200I/500 A2 inference product does not support this parameter.
sse_sum	SSE of the current frame. The formula for calculating the SSE varies according to the software. Therefore, the SSE also varies.
sse_lcu_cnt	Number of LCUs in the current frame.
psnr_val	PSNR of the current frame. The formula for calculating the PSNR varies according to the software. Therefore, the PSNR also varies. For H.264, the psnr_val value can be obtained only when the product of the input image resolution is less than 4096 x 2032. For H.265, the psnr_val value can be obtained only when the product of the input image resolution is less than 8192 x 4064.
