Comment (by safinaskar):
I got similar problem one time. I captured screen using x11grab, output
video had mostly correct fps, but there are fragments with unusually high
fps. It turned out that such fragments follow periods when my computer is
in suspend mode. So my guess is so: when computer is suspended, ffmpeg is
unable to capture frames, and when the computer wakes up, ffmpeg tries to
"catch up" and thus temporary raises fps. If I remember correctly I fixed
this by replacing "-r NUMBER" with "-framerate NUMBER"
