I have successfully build QT 5.8.0 on nVidia TX1 board.
But with QML video surface sink element still getting Reddish preview.

I also tried 5.8.0 QT C++ camera example.
but for this example camera preview seen for 1-2 sec and then ubuntu hangs. And also the preview appear with wrong color conversion format.

So i tried minimal camera example.

But when i start camera following error comes
Unable to open the camera "" for read to query the parameter info: "No such file or directory"

So how can i preview UYVY camera preview in this example?

Here is a complete workshop explaining how to handle the Camera with QtQuick - in addition the demo project in github shows how to read QRCodes with QZXing :
