    v4l2: Add protection when set decoder capture fps accroding to output fps · 0e7a4855

    Some v4l2 drivers don't have the capacity to change framerate. There is
    chance to make decoder capture fps to be 0/0 if numerator and denominator
    returned by G_PARM ioctl are both 0. It causes critical warning
    "passed '0' as denominator for `GstFraction'".
    
    In order to fix this, add protection when set decoder capture fps according
    to output fps.
