Members

Member	Description
residual_bits	Number of residual bits in the current frame.
head_bits	Number of header bits in the current frame.
madi_val	MADi value of the spatial texture complexity of the current frame.
madp_val	MADp value of the temporal motion complexity of 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. The psnr_val value can be obtained only when the product of the input image resolution is less than 8192 x 4064.
sse_lcu_cnt	Number of LCUs in the current frame.
sse_sum	SSE of the current frame. The formula for calculating the SSE varies according to the software. Therefore, the SSE also varies.
sse_info	SSE of the eight regions in the current frame. The formula for calculating the SSE varies according to the software. Therefore, the SSE also varies. #define HI_VENC_MAX_SSE_NUM 8
qp_hist	QP histogram of the current frame. #define HI_VENC_QP_HIST_NUM 52
move_scene32x32_num	Number of 32 x 32 foreground CUs in the current frame. The foreground macroblock-level stream control needs to be enabled.
move_scene_bits	Number of foreground bits in the current frame. The foreground macroblock-level stream control needs to be enabled.
