Hello! I am working on a project that is developing a custom PCB for a video processing application. The PCB includes an MPSoC and analog video decoder / encoder chips for performing ADC / DAC functions, with the parallel video data connected to HPIO banks on the MPSoC. Inside the FPGA, we are planning to use the Video-In-to-AXI4S (PG043) and AXI4S-to-Video-Out (PG044) IP cores. I have a couple of questions about related Linux drivers:
1) Video input: I have previously used the V4L2 driver as part of the SDI and HDMI drivers, but I have not tried to use it directly with a standalone Video-In-to-AXI4S core. Can the V4L2 driver be used directly with a standalone Video-In-to-AXI4S core?
2) Video output: I have previously used the DRM KMS driver as part of the DRM KMS SDI-TX driver. The Wiki page for the former does not list AXI4S-to-Video-Out as a supported IP core. Should I be able to use it in this mode? Or could I hook up a Video Mixer to the AXI4S-to-Video-Out core, which then connects to HPIO pins? The Video Mixer core is listed as a supported IP core for the DRM KMS driver.
Thank you very much in advance for your help with these questions!
