More noob questions on USB Camera activation

[gwynethh]

Is there a hot key combination to open the backup camera?

Has anyone successfully used the backup sense connection on the CarPiHat to activate the backup camera?

Thanx Again!

In Hudiy, there are essentially two ways to display the reverse camera view. The first is using the built-in camera view, and the second is using HTML/JavaScript.

Built-in camera view

For the built-in camera view, you can use actions (show_reverse_camera/hide_reverse_camera) to show/hide the view. You can trigger these actions via the API or using shortcuts/menus. You can also use dedicated SetReverseCameraStatus message.

The API example for triggering reverse camera is available on our GitHub: https://github.com/wiboma/hudiy/blob/ma ... eCamera.py
https://github.com/wiboma/hudiy/blob/ma ... proto#L121

To trigger, for example, show_reverse_camera via the menu or shortcuts, you simply need to add the appropriate entry to applications_menu.json or shortcuts.json.

The built-in camera view uses GStreamer to render the camera feed. You can customize the pipeline to your needs in main_configuration.json: https://github.com/wiboma/hudiy/blob/ma ... ersecamera

HTML/JavaScript
An example of displaying the camera feed using HTML/JavaScript is also available on our GitHub. You can integrate it into Hudiy as an application or an overlay, and show or hide it via the API, shortcuts, or menus.

If you configure it as an overlay, its visibility can also be controlled via the API: https://github.com/wiboma/hudiy/blob/ma ... ibility.py
https://github.com/wiboma/hudiy/blob/ma ... proto#L701

There is also a topic on the forum about HTML/JavaScript camera view with guidelines: viewtopic.php?t=38
