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, peak signal-to-noise ratio (PSNR) value 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 largest coding units (LCUs) in the current frame.
sse_sum	Int, sum of squared errors (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_scene16x16_num	Int, number of 16x16 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.
