PS C:\Users\djcim>
Not sure if it is because I'm recording different sources but I'm
definitely dropping less frames pre-recording as I was even testing
previously today, yet I am dropping none the less. I drop a lot more frames
when ending the recording, I would think this is because the buffer is
being offloaded to the encoder all at once, but I'm not sure.

I just wasn't sure if it was as simple as switching the variable being
passed, I'm having a difficult time understanding the source code. I have
yet to compile FFmpeg myself but I'm sure I could figure it out one way or
another.
