This is a set of three media entity subdevice drivers for the i.MX Image Converter: - Pre-process Router: Takes input frames from CSI0, CSI1, or VDIC. Two output pads enable either or both of the preprocess tasks below. If the input is from one of the CSIs, both proprocess task links can be enabled to process frames from that CSI simultaneously. If the input is the VDIC, only the Pre-processing Viewfinder task link can be enabled. - Pre-processing Encode task: video frames are routed directly from the CSI and can be scaled, color-space converted, and rotated. Scaled output is limited to 1024x1024 resolution. Output frames are routed to the prpenc capture device. - Pre-processing Viewfinder task: this task can perform the same conversions as the pre-process encode task, but in addition can be used for hardware motion compensated deinterlacing. Frames can come either directly from the CSI or from the VDIC. Scaled output is limited to 1024x1024 resolution. Output frames are routed to the prpvf capture device.
