What sort of Video Inputs (not camera inputs) can be directly connected to the processor and on which pins?

VPU is Video Processing Unit, which doesn't connect from peripheral directly, if you need to use encoder, can from camera as source or from video file

I have received the answer to my question but the answer has pushed me to look for an alternative processor

I am looking for a processor with:

1. Multiple ARM cores

2. Graphics processor with support for OpenGL ES 2.0 or higher

3. Video processor with support for Video Inputs like DVI/HDMI and/or 24-bit digital RGB. Availability of H.264/H.265 will be a bonus but is not mandatory for my application.

4. Device drivers compliant with VxWorks 7.0

i.mx8mm doesn't support dvi or hdmi input directly, but imx8qm does

Thanks. Let me look up the datasheet

I just looked up the imx8qm datasheet but I find that the HDMI is only for output use. As mentioned in my earlier post I require HDMI/DVI input port.

you can refer to the imx8qm schematic, imx8qm has hdmi RX port:

you also can refer to my document as below:
