[libcamera-devel] [RFC/PATCH 3/5] qcam: Add an option to allow specifying output path

[Niklas Söderlund]

Add a command line option to specify an output path for files captured.
This will become more useful when JPEG capture is turned into an quick
operation instead of using a QFileDialog and when RAW capture support is
added.
