The broadcast is lagging / pausing / buffering. What could be the problem?

If the broadcast is pausing, lagging, or buffering for some but not all viewers, then likely the viewers download speed is not fast enough for the bitrate you are streaming at. You can ask affected viewers to test their download speed at http://www.speakeasy.net/speedtest/ and see if that might be the problem. If their download speed is anything close to or less than the bitrate you are streaming at, then it's fair to conclude that their download speed is the issue. If this is the issue you can try lowering the broadcast bitrate in order to lower the download speed required to watch without buffering.

On the other hand if all users are experiencing the same issue there are two possibilities:

1. Insufficient upload speed.

Inside Adobe Flash Media Live Encoder near the center bottom of the window it shows the 'Total bandwidth required to stream'. Your upload speed should be at least 30% faster than the total bitrate shown. Also if you are behind a WiFi connection keep in mind bandwidth can fluctuate dramatically with wireless connections. You can test your upload speed at http://www.speakeasy.net/speedtest/ and if needed, lower the broadcast bitrate to accommodate your upload speed.

2. Insufficient CPU power

If your computer CPU can't keep up with the encoding process, this would most likely result in dropped frames. During a broadcast, you can see if there are any frames being dropped by looking at what is being reported for Output Drops in Flash Media Live Encoders Statistics window.  If you are using a Windows computer, also check your CPU usage by bringing up Task Manager and clicking on the Performance tab. What does it show for CPU usage? Anything over 70% suggests you need to either change your FMLE settings to use less CPU power (e.g. lower bitrate and frame rate) or get a faster computer. Also if the RAM memory is being reported as mostly full then that could also be the issue. Multi bitrate broadcasts are more likely to encounter this problem since they require significantly more CPU power.

If you have dismissed these possibilities and continue to have problems please contact support for assistance.
