I have the following Python code that would make a GUI for the command line process of turning a video into frames that is native to VLC Media Player.
# -*- coding: utf-8 -*-
from subprocess import call
import wx
import wx.xrc
vidpath = ''
framedir = ''
def VideoToFrame(videopath, targetdirpath):
"Converts a video into frames. Make sure you have VLC Media Player installed!"
call('vlc.exe "' + videopath + '" --video-filter=scene --vout=dummy --start-time=300 --stop-time=600 --scene-ratio=250 --scene-path=”' + targetdirpath + '” vlc://quit')

Unfortunately I couldn't manage the frame to show when I ran the script. The result was... nothing! Please help! I have no idea of what I am doing, and no other idea of how to make a GUI of a command line process. I am a good Python player though.
I don't see where you created an instance of your MyFrame1
add:
app = wx.App()
frame = MyFrame1(None)
frame.Show()
app.MainLoop()
