I was playing with the exemple camera app from kivy website, but I have encounter a probleme.

(link for the kivy code : https://kivy.org/doc/stable/examples/gen__camera__main__py.html )

I have a Mi9 SE, and so I have 4 camera on my phone.

When using the “index: 0” every worked perfecly.

I wanted to acces te selfi camera, but here the problems begin.

I have try index from 1 to 6 and every time I have an “resolution” error.

The index -1 give me nothing the app dosen’t crash but no player start.

I’ve also try reolution (320,240) didin’t change the result.

If you have any clue on how to have acces to the seflie camera, I will be grateful for your anser.
