Hi,
Main problem to Integrate Live lib with Directshow filter is the thread
synchronization. To overcome that I define Live Thread as another Worker
thread of DS filter. I got test.mpg stream on VLC player, but not
sequential rendered, meaning I have about 4500 frames that the filter
inserted in a queue. Although my deliverefFrame method process from the
queue only 700 frames, (that explain the video behavior). My
MPEG1or2LiveSource(Subclass of FramedSource) implementation followed by
the new DeviceSource with EventTrigger.
My conclusion is that live thread is not keep-up with the frames
received thread. In order to control live thread I had to subclass in
BasicTaskScheduler0 and implement doEventLoop as a singleStep to avoid
the BasicTaskScheduler0::doEventLoop endless loop.
Question:
1) Is it right to call delivered frame from doGetNextFrame this way?
if (!gOutputQueue->empty()) // Queue is Not empty, deliver frame.
deliverFrame();
2) If yes for the previous question and I'm using the triggerEvent for
every frame I'm pushing to the queue. deliverFrame method is called from
doGetNextFrame also from the triggerEvent in SingleStep method, it does
not make sense?
myCAMThread_RTSP.scheduler->triggerEvent(MPEG1or2LiveSource::eventTrigge
rId,myCAMThread_RTSP.mpeg1or2LiveSource);
3) In order to synchronize between the pulling and pushing of the frames
in the queue should I consider changing MAX_SCHEDULER_GRANULARITY of
schedulerTickTask?
Thanks
Eyal
