Rear camera freezing after 5 seconds - Splewi - 08-17-2021 Hey there, I have my setup mostly worked out, but I'm having issues with the camera freezing the system after 5 seconds of use. Toggling the pins for the camera, pressing Ctrl+c, signaling the pins attached to the shutdown script, and anything else I try is futile. I'm running a rpi4 with openauto pro 13.2 Using the MakerFocus Raspberry Pi4 Camera... https://www.amazon.com/dp/B07DPNDP6R And Arducam CSI to HDMI Cable... https://www.amazon.com/dp/B06XDNBM63 The camera doesn't seem to work with the V4L2 backend, but will on finder when set to 1080(at least for 5 seconds when it freezes) Running raspivid -t 0 works just fine for up to 5 minutes when I stopped it. And this is repeatable for me. (I saw "script" as a backend type, is it possible to just use something akin to raspivid -t 0 when I trigger the rear cam?) raspivid also has a LOT less delay on screen. I'm new to the pi and this one has me stumped and my google-fu didn't cut it. Any suggestions or ideas would be deeply appreciated. RE: Rear camera freezing after 5 seconds - BlueWave - 08-17-2021 How much ram your Pi4 has? It looks like video memory is leaking somewhere (maybe in the driver?).

It's the 4gb version. How would I go about checking that out/rectifying memory leakage? Thanks for the reply! RE: Rear camera freezing after 5 seconds - Splewi - 08-19-2021 I found where I can set the path for the "script" backend. In /home/pi/.openauto/config/openauto_system.ini I tried pointing it to a shell script with "raspivid -t 0" just for a test and that worked. As you can imagine, however, switching out of reverse doesn't end the script. So I'm wondering what a decent way to go about it would be. I imagine python? Never worked with it before tho. I'd like something like this But I don't know where to start or what examples would be relevant. I do have a concern with this script, pressing the " rear camera" button probably won't play well. But I'm not sure. Any input would be great! Thanks! RE: Rear camera freezing after 5 seconds - wkl3968 - 04-26-2022 mine reverse camera freezes too and I cannot do anything beyond this. can I run the reverse video command outside of OPA as in not using openauto_system.ini? like triggering using canbus services that directly run the cvlc instead using canbus to trigger gpio to tell OPA to trigger the reverse camera script?
