my config for mpc-be windowed mode:
- Minimal Preset (no window bar, hidden Menubar, hidden Toolbar)
- keep Flybar (displays when the mouse hovers at the top of the window and times out unless locked)
+ seekbar
- Show OSD + show seek time enabled, show filename disabled (can be toggled in Options>Player without restarting the player)
- HideWindowedMousePointer (time out)
- Window Size: after starting Playback, scale to video size: 100%.
- SnapToDesktopEdges.
The screenshot shows the default flybar, it's possible to change it by putting a custom flybar.svg file in the mpc-be folder.
Chapter markers can be displayed in the seekbar by toggling Options > Player > Interface > x use Chapter Markers.
When enabled the OSD display can show filename, playtime, clock, and feedback information such as Volume, Zoom. However no time-out is applied when the OSD keyboard shortcuts are used (it's ON until you toggle OFF, even restarting the player doesn't help!).
In fullscreen mode I would typically prefer the default Normal preset (the toolbar/seekbar autohide) with full OSD, but I don't think it is possible to configure two different custom setups for windowed and fullscreen mode.
