[Live-devel] Issue faced with JPEGVideo

[Ryan Chong]

Hi Ross, 

Thanks for the reply. I have tried that by adding the following code:
void JPEGVideoFileSource::doStopGettingFrames() {
        envir().taskScheduler().unscheduleDelayedTask(nextTask());
        nextTask() = NULL;
}

Then I found the problem that, when the stream is resume with the PLAY
command, there are a few seconds of video missing, normally more than 2
seconds. Is there anyway to overcome this issue?

Thanks.

Ryan
