But it seems to work with -yuv. I started the command and then slowly counted
from 0 to 5 with my fingers. The output video starts with "2", so there seems
to be a delay of about 2 seconds between start of the pipeline and actual
recording. However the video looks good, the beginning is just cut off (no
jumping etc)
