Thanks a lot for your advices.

I wish you good luck, I failed to use Jitsi Meet for a similar purpose.

Try

Code:

sudo apt install gstreamer1.0-libcamera gstreamer1.0-plugins-bad

If it's not enough, enter

Code:

sudo apt-cache search gstreamer

Maybe you'll find the right packages to install.

It's strange, videoconvert should be in gstreamer1.0-plugins-base.

Thanks for your advice, be appear, a problem is again present with ov5640 camera.

I don't know does it help but if you get it working you are most likely the first
Or in other words I am quite sure that it is not going to work by just installing some packages
But I am so happy if I am wrong and if you find a way then please post how you did it

[Kevin Kofler]

There is basically no way to use the camera in video applications until someone gets libcamera to work with it. GStreamer does not support this camera setup (with two cameras multiplexed into one device) without libcamera, whereas with libcamera, you currently get the errors quoted above.
