2 programs in 1 depending on how it's called.
These programs depend on ffmpeg (ffmpeg ffprobe ffplay) and gtkdialog.
gplay is a media player (audio and video) using ffplay and gtkdialog. I basically re-wrote ffplay-gtk since that has many issues and I think gplay is much better.
gcut will cut and save portions of your selected audio or video and merge your cut files if you'd like to do that as well.
