[Interest] Assert in QCamera on winrt tablet

[Maurice Kalinowski]

Hi,

First of all we need to know which version of Qt you are using? I have been doing quite a lot of update on the camera recently, with most (but not all) changes being in 5.6.1.

Some are in 5.6.2 and will be available in 5.7.1 as well, hence the question.

BR,
Maurice
