MIMX8MQ6D (8M Quad)

Please inquire about product specifications.
Table 1. Features are marked as follows.
Video Processing Unit
• 4Kp60 HEVC/H.265 main, and main 10 decoder
• 4Kp60 VP9 decoder
• 4Kp30 AVC/H.264 decoder
• 1080p60 MPEG-2, MPEG-4p2, VC-1, VP8, RV9, AVS, MJPEG, H.263 decoder

For the i.MX8M, there is only Two MIPI-CSI for signal input.
Table 1. Looking at the features, does it mean that you can receive 4Kp60 input with Two MIPI-CSI?
When you get input on two MIPIs, you can get 4Kp60 right?

Please review.
I hope you have a warm winter.
thank you.
