Don't mark generated dummy frame output from mpeg1/2 decoder as keyframe.
We use this flag to tell when to assume decoded data is free
from artifacts after a seek. The mpeg1/2 decoder will generate
a dummy frame if decoding is started on a non keyframe. This
will sadly be output from decoder to player and displayed
as a gray screen.
