Hi

I have the same problem as the others.

We are streaming from core i5 or i7 laptops, with Intel HD graphics and minimum 4GB RAM. We use USB grabber devices (cheap Easycap ones), and connect DV cameras via composite or S-video cables.

We always stream sound and video from the same unit so it should be in synch. Trouble is, some of our viewers experience an out of synch stream while others don't.

We even tried playing with bitrate cause we thought that maybe it was too high for some people but it didn't seem to solve the problem.

As per our bandwith, we tried several locations (in Poland) and had from 1.5Mb - 50Mb of upload. The only thing may be ping values - sometimes as high as 170-180 ms due to the distance from NY.

Of course we are using the 20.3 procaster version.

Any thoughts what might help?

mamik,

We don't support Easycap devices at this time. That could be the reason for the issue if you have 50mbps upstream to New York on a dedicated connection.

elimva,

You may want to try marrying the audio and video sources. Bringing video in through a capture device and audio in through aux is the likely reason for your broadcasts losing AV sync.
