No, if this code is (as I assume) derived from "DeviceSource.cpp", then you
should leave the first parameter to "scheduleDelayedTask()" as 0. But
instead, you should set "fDurationInMicroseconds" to be the correct
duration of the frame (in microseconds) - e.g., 20.
Setting the first parameter of the "scheduleDelayedTask()" call to 20 is
*not* the right thing to do. (This causes the delivery of the frame to the
next object in the chain to be delayed 20 us, which in turn will cause the
next packet to be sent 20 us late. That is not what you want. Instead,
you want to delay 20 us *after* sending the next packet. Setting
"fDurationInMicroseconds" to 20 will do this.)
