FFmpeg, please talk to me.

Guys,
Trying to listen to FFmpeg output, and ‘sometimes’ strange things happen.

On Windows 10, tried running FFmpeg from a batch file while redirecting the FFMpeg output to a file.
Then, during it’s work, my work copies the file to a fresh one, open it and read the contents.
When FFmpeg tells my work that it’s done, I try to delete the output.txt files.
However, sometimes they are locked. Any clues how that can happen?

Now, I switched to plan B. Shelling to FFmpeg and listen to StdOut.
(Ok, a more logical approach, but there was a reason for Plan A, don’t ask…)
This all seems to work fine, except that FFmpeg every now and then returns:
    Exiting normally, received signal 15
(Here I've switched to Win 7 for testing)
But I’m pretty sure I did not send a cmd-Q or alike…
And it’s totally random when it happens. FFmpeg is just rewrapping ProRes QT with a bit of audio patching.

It’s not a biggy, as I can catch it and fire the same command again, but nevertheless I’d like to know what I’m doing wrong.

thx,

Bouke
