Probably I'm doing something wrong, but adding the fifo filter didn't
help. I'm not exactly sure how/where I should be using it.
I changed my original command to use this filter_complex:
-filter_complex 'fifo; [0:v][0:3]overlay'
I still see the buffer overflow warnings. But the problem isn't just that
I see these warnings, the problem is the resulting video doesn't play
correctly. At a couple points, the video stalls and the audio continues
for several seconds, then the video skips ahead.
