Hi guys
I have a little problem
I am using the C790 and testing it with rpi 5b 8gb running on pi lite 64bit kernel 6.6.51
Besides multiple tutorials i had the most luck with this one: https://github.com/FearL0rd/RPi5_hdmi_in_card/tree/main
Now this kinda works when i capture something via v4l2-ctl to a yuv file and the module is connected to my PC
But as soon as i try to use it via the HDMI Splitter in my Setup i only get a black screen/output
The switch is this one: https://www.amazon.de/dp/B07D6WYJTN?tag=hyperioforum-21&ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
It should divide the output to 4k@60 and 1080p@60
It seems like v4l2-ctl also detects the correct width/height and framerate but somehow i only get a black image 
Besides that i tried installing hyperion which worked
But when i activated usb capture i had two options rp1xxxxxx/image0 and rp1xxxxxx/image1 (dont remember the correct names mby it was rp1-cfe)
Now the problem is as soon as i select one of those 2 and also entered the resolution and framerate hyperion crashed
It crashed so hard that not even a reinstall helped recover
Only a complete reinstall of the os and installing hyperion again worked for me
It didnt matter which of those two options i selected or if i left the resolution blank it crashed every time
Hope someone can help steer me in the right direction
Thanks in advance
