[Live-devel] Live555 EventLoop Crash

Hi Ross,

(subclass)?  If so, then you should be seeing

creating this 'RTPSink'.

No I don't see this error message, however I am seeing continuous
truncations, almost every frame is truncated. My own debug output looks like
this, at a rate of around 4 frames per second:-

deliverFrame(): newFrameSize:216054, fNumTruncatedBytes:66055 

deliverFrame(): newFrameSize:108994, fNumTruncatedBytes:98217 

deliverFrame():newFrameSize:96844, fNumTruncatedBytes :45293

 

I've tried increasing OutPacketBuffer::maxSize from 1000000 to 5000000 (5
million) but this has no effect. Am I just trying to stream too much data,
too quickly? Is it that however large you make the output buffer, it's going
to fill up if it can't stream out fast enough? How do I get it to drop
frames or GOPs sensibly without truncation? Remember, this is an in-camera
