Members

Member	Description
residual_bits	Int, number of residuals (bits) of the current frame.
head_bits	Int, number of bits in the header of the current frame.
madi_val	Int, MADi value of the spatial texture complexity of the current frame.
madp_val	Int, MADp value of the temporal motion complexity of the current frame.
psnr_val	Int, 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 resolution of the input image is less than or equal to 3840 x 2160.
sse_lcu_cnt	Int, number of the 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	List, SSE of eight regions in the current frame. The formula for calculating the SSE varies according to the software. Therefore, the SSE also varies.
qp_hist	List, QP histogram of the current frame.
move_scene32x32_num	Int, number of 32 x 32 foreground blocks in the current frame. The foreground macroblock-level bit rate control needs to be enabled.
move_scene_bits	Int, number of foreground bits in the current frame. The foreground macroblock-level bit rate control needs to be enabled.
