Still the same problem.... I can have Pixymon built, but failed to grab any image ...

$ sudo ./PixyMon 
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QFSFileEngine::open: No file name specified

Pixy detected.

However, I cannot see the grabbed image/video, just black out.

What's obtained from terminal are:

$ sudo ./PixyMon 
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QFSFileEngine::open: No file name specified
