Sound and video are late after 15 minutes of conferencing #731

GoogleCodeExporter commented 9 years ago
We've tried a long conference (about 1 hour) for 5 people. We found a 
problem that becomes so clear after approx. 15 minutes of active 
communications.

Sound and video comes late for minutes. (E.g., you say a word, and your 
colleague hears it in 2 minutes). It looked like some buffer overflowed. It 
clearly was not because of bandwidth or other network problems. 

Some ways to fix it:
1) Each moment audio stream is accepted from 2 persons, not all others are 
silent.
2) Do not transmit silent sounds to a server (set some threshold using 
flash settings).
3) Clear the buffer time after time.

Which version of OpenMeetings are you running?
0.8 rc2

We found out that the lags appear when network bandwidth is insufficient. This 
might
be a good case to research heuristics to drop outdated or low quality packets 
on the
server side. But well, the client won't be happy with low quality channels 
anyway.
