Camera Preview in app

[Strankler]

Description:
After connecting the app with the mobile, I can see the picture on the mobile, and that the connection is made correctly. But I can't see it in the app.

Problem:
I have 3D printed a bracket, to mount my mobile backwards on the monitor so that the camera points in my direction. But with this setup, I don't see the screen of the mobile anymore, and so have no clue if it works, or if the camera is orientated properly. (except, I 'd walk around the table, or do some silly moves to try to have a look at the back of my monitor).
Of course I can open an appropriate program like "Cheese" to check, but "Cheese" don't work stable with droidcam (It interrupts after a few seconds).

Feature Request:
Implementation of a camera preview into the app to see immediately if the connection with the camera-device works correctly, and to have a chance to orientate the camera view before entering a video conference.

you can start a quick preview using:

ffplay -f video4linux2 -framerate 30 -video_size hd1080 /dev/video0  # adjust the params...

this could be binded to a shortcut key

Workarounds:

• The above suggestion with ffplay.
• Use of a browser (via the http://... endpoint) if the webcam isn't needed, just a preview.
• Using OBS Studio along with the DroidCamOBS app + plugin (which may get its own client in the near future)

Rendering a preview on Linux would require a big-ish overhaul.
