Hi Simon / All -

Useful to know about "-nostdin" -  I need to spend more time rtfm.

However, update on my issue: I'm not sure where the bug lies, but I was 
incorrect about stdin being the problem. It was a coincidence that 
PAExec crashed near when "Press [q] to stop..." was output from FFmpeg.

By passing "-loglevel error" (or above), and passing "-hide_banner", 
PAExec no longer crashes and I'm able to automate FFmpeg as needed. I 
can only assume there are some interesting characters that I'm avoiding 
printing out from FFmpeg, that crash PAExec.

For anyone that's interested, I'm also passing "-stats" so that I still 
can track progress from stderr.
