Hi,
My use-case is an avionics DVR.
I am using Linux R35.5.0 (Jetpack 5.1.3) with a custom carrier board.
I have modified the device tree and ov5693 driver to support camera capture from an FPGA.
In this use-case the data path is NTSC composite camera 720x480 ->ADV7842->FPGA->Jetson MIPI.
De-interlacing to 480p is done by ADV7842. Jetson captures at 768x480 to obey 64 byte stride alignment requirement. I use nvidconv to remove the extra 48 pixels per line. This works fine but when there is horizontal motion near the top of the frame tearing occurs.
Running “/usr/bin/jetson_clocks” prior does not fix the issue.
Putting an extra “queue” before nvvidconv does not fix the issue.
Please advise on how to resolve this.
