Hello
we are using Ultra 96 v2 board for an AI - Imaging Processing application. Running pynq with the Ubuntu version 18.04. We operate on the CPU side.
For video streaming we use the Camera DFK37BUX273: https://www.theimagingsource.de/produkte/industriekameras/usb-3.1-farbe/dfk37bux273/
Driver: https://www.theimagingsource.de/support/software-f%C3%BCr-linux/installieren/tiscameradutilsarm64/
We only achieve a Framerate of about 15 FPS. We need to have at least 30 FPS for our Application.
Do you have experience on the described constellation/system?
Thank you in advance.
Regards
Roger

Hi @rokarlen
What is your target resolution ?
It's relevant of your target resolution.

Yes, we need 1440*1080 rgb. The camera supports only 640*480 and 1440*1080. We need the higher resolution.

How do you transfer videostream from USB to internal ?
Did you make sure cache status and/or DMA mode ?

We use dev/video0 with the tiscamera dutilsarm64 with the bayer2rgb method.
Cache status and DMA mode I don't know. We only know that it runs on 1 core with 98% performormance.

Make sure io-mode, if you use v4l2src element on gstreamer pipeline.

Also, you might get some suggestion, if you share more details.
