Automatic detection generate error

[costeacostin]

Hello,

I tried to set up the UVC parameters with the automatic params detection (which I found pretty interesting btw) and it fails.
I tried to debug it and so on but I didn't found anything relevant.

Hello costeacostin,

thx for debugging the app.
This failure is because your camera supports more than one format indexes, but this case isn't included so far in my app.

I will solve it soon.

ok, plz update your app from github and try it out again ...

Note:

The Automatic Detections is in beta Development for now. A lot of cases of setting up the values for different cameras on different devices are not included for now.

The latest Driver of this app works better with every camera. The Auto Detection will remain in Beta I think, because it's heavy complicated to get every camera with every phone runnung, without any malfunctions.
