Starting Depthai Viewer

michaelsalerno · Aug 16, 2024

It works once and a while, then when it doesn't, it sends me this error

I think it should also sort itself out if you give it a minute

@filipjeretina

Do you think this error is just coming from me starting and stopping so frequently?

filipjeretina · Aug 16, 2024

hmm, no. You can play arround with the camera FPS and lower it until it works for you

filipjeretina · Aug 16, 2024

Maybe drop it to 5fps and see if that works, if yes, go up, until it doesn't work

michaelsalerno · Aug 16, 2024

@filipjeretina

So the FPS is what will determine if the device will turn on consistently?

michaelsalerno · Aug 16, 2024

@filipjeretina

Regardless if I go to 5 or to 15, it seems to be luck with when it decides to turn the viewing window on or off

michaelsalerno · Aug 16, 2024

@filipjeretina

But this error remains consistent

@filipjeretina

I am able to get it to work maybe 25% of the time

@michaelsalerno
Might be that the PC is unable to supply enough power on the USB port, hence the device crash when using more complex pipeline. Could you try a different power source/splitter?

Thanks, @filipjeretina
