# PiPlayer
Simple GUI around OMXPlayer
PiPlayer is a very simple GUI around the OMXPlayer on the Raspberry Pi.
OMXPlayer is a quite basic player using the hardware decoding features of the Raspberry Pi for decoding HD videos. This GUI is intended to be used with other tools like smtube, which do not give you the opportunity to open a terminal for controlling OMXPlayer. You can now use PiPlayer for controlling OMXPlayer.
The file ```dbuscontrol.sh``` is not written by me! I take no authorship in that bash-skript. I copied it from [popcornmix's repository](https://github.com/popcornmix/omxplayer)
## Technical mumbo-jumbo
PiPlayer quite litterely calls omxplayer and communicated to it via the DBus-interface. There are some functions not present in the GUI, which could be reached via the ```dbuscontrol.sh```-bash skript.
The window is placed on the screen and omxplayer is called with the ```--win``` parameter to fit exactly inside the window. On resize of the window a DBus-interface is called to adjust for the new size of the window. That works well for maximizing, resizing or moving the window, but not for restoring it from maximized setting to normal. For that reason the OMXPlayer-output cannot be placed in the background, whereas the player-window can be in the background.
## Usage
You need the ```pyFLTK```-package for your Python-installation. Best to get it from the website (at least ArchLinux ARM) does not have the package in its repositories. For pyFLTK to work you of course need also the FLTK-package of your distribution (fltk1.3).
Then you should be able to call it via a CPython3-interpreter (as far as I know the pypy-interpreter does not support pyFLTK):
```
python piplayer.py filename
```
You can also give parameters which will be directly handed to omxplayer on startup.
