Doesn't start properly on bookworm raspberry pi5 (installed via apt install webcamoid).

Keeps drawing screen infinitely in smaller and smaller windows.

Does it detect the cameras?

[mgrouch]

There is no cameras. I’m just starting the app

[hipersayanX]

Then it started properly, if you have not any camera installed, it will capture the screen as expected.

[mgrouch]

It goes into crazy loop of capturing screen
and keeps scaling images smaller and smaller.

Look horrible. Like two mirrors facing each other.
I doubt it’s expected

[hipersayanX]

You are capturing the screen with the window maximized, how would you expect it to look like then?

Look horrible. Like two mirrors facing each other.

Superstitious thinking? 😆

[mgrouch]

It never stops capturing. It looks like it hanged in a loop

[hipersayanX]

Also, another funny effect to try: if you have an external camera, point to the screen were th Webcamoid window is located, and make Webcamoid capture from that camera, and turn the camera a bit, you will be able to open a portal to another dimension. 😆

If you think this is a bug, you can report the "bug" to X.Org, Microsoft, Apple, Google, and every single operating system implementing a desktop capture.

Also open an issue in the FFmpeg tracker, because they have the same "bug":

ffplay  -f x11grab -i :0.0

GStreamer is also "bugged" 😟

gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw,framerate=30/1 ! videoscale method=0 ! ximagesink

Here is the video of the issue

from another user

[hipersayanX]

He is using an old version, and is not detecting the camera or he hasn't a camera connected. You said that you have not a camera connected to your Raspberry Pi, that's why it's capturing from the screen.
The screen capture loop is not a bug.

They are bad. For most of sane users it’s impossible to understand what is going on in UI when something like this shows up

[hipersayanX]

You are not the first one asking for this 😆
All streaming programs with screen sharing support can do the same, and most users are not streamers so it may seem confusing at first 😆
Some users even think this effect consume more memory or CPU when it isn't.

[mgrouch]

It’s a very trippy effect. Makes it unusable for a non trippy user.
