Implemented and committed DNGFileFolder. No tests done, because of missing necessary changes on OC, e.g. POCO library not committed atm. Work in progress.

• First problem occurred: How to handle different data types? Same data provider but different visitors (Visitor Pattern) for different types?

Next tasks:

• Rework logic (MediaExplorerPresenter.cpp)

_model = new MediaExplorerModel(_context->GetDefaultDataProvider());

Default theme:

• Use apertus° palette, especially "orange" as primary highlight/indicator color

Done.

Update on "missing MediaExplorer". I tested OC with minimal Xubuntu VM. Following PPA is required https://launchpad.net/~beineri/+archive/ubuntu/opt-qt54-trusty/ to get Qt5.4 packages as they are not included in Ubuntu repository at the moment. OC complained about missing QGraphicalEffects package. After installing the MediaExplorer appeared, i think that the same behavior exists under Windows and will investigate further.

Idea exists for quite some time and the MediaExplorer was the first step in that direction. Till now i thought about import dialog where the user selects data type like MXF, DNG folder etc. and also the folder which should be scanned.

Changed handling for the buttons, but the issue will remain open for now to signalize incomplete functionality of playback controls, e.g. reverse plaback.
