hi, dear all,<br><br>I know if doGetNextFrame() reads a frame then call afterGetting() to inform the sink we have data, but how to process if doGetNextFrame() reads nothing for a while from a device ( not mean the source is invaild in my case ) and reschedule doGetNextFrame() but not inform the sink ?<br>
<br>Could I call envir().taskScheduler().scheduleDelayedTask( delayTime, (TaskFunc*)continueReadProcessing, this ) ?<br><br>thanks <br><br><br>huang<br><br><br>
