[Live-devel] Need help creating a H264 stream from a video encoder source

I presume that you're <control>-C'ing the application here because it doesn't report receiving any data.  Is the client computer on the same LAN as the server?  (Make sure that it's not behind a firewall that's blocking UDP packets.)

But assuming that there's nothing that would stop UDP packets from reaching the client, then the server must not be transmitting them, for some reason.  The only thing (as far as I can tell) that could be causing that to happen would be if there's something wrong with your H.264 NAL source, and it's not delivering proper H.264 NAL units to the downstream "H264VideoStreamDiscreteFramer".

So I'd suggest checking - in "H264VideoStreamDiscreteFramer::afterGettingFrame1()" - that it's getting reasonable-looking data, and that "frameSize" is what it should be.

But apart from that, I don't know what to suggest.
