Camera Dark/Blue in OAP - madtripper - 12-30-2019
I recently installed V5.0 to my pi 3B+. I am bench testing everything as I have many parts going into my project. As it stands, I have the official pi touch display @ 7", Miuzei camera module (I have HDMI extenders as well but I get the same result both direct connecting and using the extension).
I don't have any pictures currently but what I am seeing is that when I view the camera using the app tile in OAP, the image is very dark with blue highlights. If I back out to the raspbian desktop and use the test app from main menu, the image is as it should be. I ran the following in hopes that someone will see something I may be missing. This is stock image received from BlueWave (within the last week) with no changes up to this point.

I'm having the same issue with OAP 4.0 not sure what the deal is

Here are some photos of the difference between the V4L2 capture and the view through OAP.
RE: Camera Dark/Blue in OAP - ionutd - 01-03-2020
I have the same problem plus the stream looks like it has just few frames per second.
RE: Camera Dark/Blue in OAP - BlueWave - 01-03-2020
Did you check that default V4L2 Linux settings are the same as used in program from the screenshot?

Seems that issue is reproducible for few users. We are going to have a look at this...

Any update? I'd be happy to provide info if you need. I have flashed a few times and updated but I'm still having the same issue.
Thanks

We narrowed the issue, and seems to be related to RPI3. Currently we are working on solution.
