[FFmpeg-devel] x11grab that need not time_base.den > 0

[Guijin Ding]

Hi,

When I try to test the x11grab that describe in the FFmpeg Document at
first.

the command line is

ffmpeg -f x11grab -s cif -i :0.0 /tmp/out.mpg

But the error occur. because the code find av parameter time_base.den <=0.
For x11grab it should permit time_base.den == 0, shouldn't it?
