 Summary of the bug:

 We've upgraded to newer MacBook Pro's and found that FFMpeg is now
 crashing the entire system after recording video for a few minutes. This
 isn't just an FFMpeg crash, it's an entire system crash, i.e. the screen
 goes black and the computer restarts. The crash is consistent and happens
 every single time without exception, rendering ffmpeg unusable for our

 Here are the systems I've tested on. The previous 2 MacBooks we were using
 don't have this crash (regardless of ffmpeg version). Any suggestions to
 fix this? FFMpeg is totally broken an not usable for Mac users currently.


 Macbook Pro 13" 2019 Macbook Pro 13" 2018

 Doesn't crash:

 Macbook Pro 13" Early 2015 Macbook Air 2018
