Parameters

val ulong

guint64 (such as a GstClockTime) to scale.

num int

numerator of the scale factor.

denom int

denominator of the scale factor.

Return Value

Type: ulong

val * num / denom. In the case of an overflow, this function returns G_MAXUINT64. If the result is not exactly representable as an integer, it is rounded up.
