Hi,
Can MultiFramedRTPSink::sendPacketIfNecessary() be enhanced safely with the
following code ? I would like to transmit all packets within one video frame as
soon as possible instead of scheduling packet one by one ? uSecondsToGo gets 1
usec but cause the schedule to run and actually add a lot of latency between
packets.
if (fNoFramesLeft) {
// We're done:
onSourceClosure(this);
} else {
if (fOutBuf->haveOverflowData()) {
sendNext(this);
}
else {
// We have more frames left to send. Figure out when the next frame
// is due to start playing, then make sure that we wait this long before
// sending the next packet.
struct timeval timeNow;
gettimeofday(&timeNow, NULL);
int secsDiff = fNextSendTime.tv_sec - timeNow.tv_sec;
int64_t uSecondsToGo = secsDiff*1000000 + (fNextSendTime.tv_usec -
timeNow.tv_usec);
if (uSecondsToGo < 0 || secsDiff < 0) { // sanity check: Make sure that the
time-to-delay is non-negative:
uSecondsToGo = 0;
}
// Delay this amount of time:
nextTask() = envir().taskScheduler().scheduleDelayedTask(uSecondsToGo,
(TaskFunc*)sendNext, this);
}
}
Bo
