split screen front and rearview #15

Open Bishamon1987 opened 5 years ago

Bishamon1987 commented 5 years ago

I was wondering if it is possible to add a second camera view. And a way to switch back and forth. Something like the WhatsApp video call view. One little screen for one of the views and a big view window for the other cam Or just split screen. I would like a rear and front camera for easier parking. But I also want to use them as dashcams. The front camera will be mounted underneath the front licenseplate

Hi @Bishamon1987 This should theoretically be possible by running multiple instances of cam_overlay Currently cam_overlay is fixed to one display layer and will attempt to scale the image to full screen, but the code could be tweaked to position the displayed image to whatever position you wanted.

Can you tell me where in the code i can change the display size and position?

meekys commented 5 years ago

In the cpp branch, have a look at the ScaledImage class. This is what currently transforms the image. It does things like stretching, rotating or flipping and renders the resulting image to the screen
