 // VideoScheduler would ideally schedule captures so as to saturate the slowest
 // of the capture, encode and network processes.  However, it also needs to
 // rate-limit captures to avoid overloading the host system, either by consuming
 // too much CPU, or hogging the host's graphics subsystem.
