HELLO

WE'RE CONSIDERING TO USE PIXEL LINK INTERFACE FOR 4 LANES MIPI-CSI-2 DEVICE LIKE FPD-LINK DESERIALIZER / HD-TVI  RECEIVER AND ONE PARALLEL RGB FOR HDMI RX DEVICE. OUR SYSTEM REQUIRES 2 - 4 CHANNEL INPUT WITH eDMA TO MEMORY FOR 90 DEGREE ROTATION / OVERLAY FEATURES. EACH INPUT VIDEO STREAM ASKED TO SUPPORT FULL HD 1080P AT 60 FPS IN CONFIGURABLE ON-THE-FLY GRAPHIC LAYERS OF MEMORY AND INDEPENDENT PIPELINE FOR TARGET USE CASE WITHOUT LATENCY.

 

MY QUESTION IS THAT POSSIBLE FOR 4 LANE VIDEO STREAMS AND ANOTHER ONE STREAM INPUT THROUGH HDMI RECEIVER TO BE OVERLAID TOGETHER AND ROTATION BY 90 DEGREE IN CAMERA FRAMEBUFFER?
