 Vuu-do Simple Video Player, no frills, no features, plain interface. Just video.
  * Builds a local video database from ~/Videos automatically on first run.
  * Re-scan function for adding new local videos.
  * Simple seek functions, minute or chapter, or global in fullscreen.
  * 4 different viewing modes.
  * Supports most common video formats.
  * Fullscreen window, opens a new window for Theater mode or Fullscreen.
  * Works with AlsaTune for real-time audio tweaks (if installed).

VSVP is built using ffmpeg via ffplay as the backend to play videos, it has
simple controls and is easy to use. On first run it creates your video database,
which is used to populate the hierarchical collection tree on the left. To use,
just highlight a video and hit play. The pause button toggles pause/play. The
rescan button scans ~/Videos again to add any new media you may have added.
Maximizing the GUI window takes you to quasi-theater-mode, with borders and
video menu hidden, with only the titlebar and the control buttons visible.

The "Fullscreen window" button, opens your selected video in a new window instead
of the GUI, this is a native ffplay window with keyboard controls only, it has
a theater mode if maximized (titlebar only in addition to the user's panel), 
and if you toggle the "f" key it expands to fullscreen. Some keyboard shortcuts 
are noted in the tooltip for the fullscreen window button, and the main 3 are 
noted in the titlebar of the ffplay window. You can also do a seek to anyhwere 
in the video by right-clicking in the window. Note that keyboard controls only
work in the ffplay window, not in the GUI window.

f  -  toggle fullscreen
p  -  toggle pause/play
m  -  toggle mute

q or ESC          -  quit and close window

left/right arrow  -  seek ±10s
up/down arrow     -  seek ±1min
pg up/pg dn       -  seek ±1 chapter
right-click       -  seek to cursor position

Some other things to note:

This is built on Daedalus/Bookworm libraries and will not work on newer versions
unless you re-compile it or install the older libav libraries alongside your
newer ones. Also it contains an X11-specific bit of code in it, and likely will
not work on Wayland.

The wrapper also contains a check for a running instance of vsvp and will exit
if there is, two instances do not play well together.

If you are playing a video in the GUI and decide to go for the fullscreen window,
go ahead and just click it, it will stop the video in the GUI window first. You
can however after that, start another video in the GUI if you just really want
two videos playing at the same time. At that point it's on you, have not done any
extensive testing on the ramifications of playing multiple videos simultaneously.

The initial GUI window is re-sizeable via grab-handles if you just want it a
little larger, but make sure you start the video first before working the
grab-handles as it will fail to imbed properly if you do it before a video plays.
