Program to keep track of reading time

[snippsat]

I was wondering if such a thing is possible using psutil module (say, for eg., to get the name of the video file VLC player is playing when it is active).

psutil can find if a process is running.
The problem is finding out what the process dos internally as eg OneNote may not give any info to stdout/stdin that can be captured.
VLC is open source,so here can people hack into the running process and try to get some info.
Now Playing is see that used a Lua script to get info what's playing live from the running VLC process.
