mpv window freeze before video end

Hi all,
my little program actually seems to work - fast over Ethernet, not so fast over WiFi.
But, it controls and views clips and images produced by motion, and it allows for moving (archiving), copying, and deleting images or clips.
If it is OK, I would like to post the whole thing either for comments or suggestions. And,if anyone thinks it's usable, go ahead, use.
Is it OK to post here?

I will try to figure out how to do it with GitHub. I would be a bit embarrassed because it is not much, and I am certainly not able to give people great insight since I am new to Python. Still do it?
The code is 240+ lines - I can insert it into here also? I am not looking for fame and certainly not money, just hoping someone else can also use it who uses motion durveillance.
