Question

FMS 3 - Choppy Live Video

We were using FMS2 for a while and recently switched to 3.0.2, ever since then our video is being really choppy. The config files changed quite a bit so we are unsure if we missed settings somewhere or what. Our stream used to be extremely smooth. We are using on2 vp6 for our streaming, we use stream from digital rapids and we push 2 streams up 512k and 350k. The network checked out fine from our streaming location. We currently have 1 origin and 2 edge servers.

Anything you guys can point us towards would be great.

EDIT: We noticed a better stream going back to FME, from Streams. We are calling Streams on Monday to see if its a version issue since we switched to FMS3.

    To increase server performance, FMS 3 comes up with Aggregate Messages(new feature) set to enabled in Application.xml. This might introduce a choppy experience when NetStream buffer on client side is very small.

    Assuming that it might be the real cause in this case, the fix includes:

    - Increasing NetStream buffer on client side to a suitably higher value (1-5 seconds or more).

    - (when delay due to buffering is undesirable) Modifying Application.xml to disable Aggregate messages/publisher queues.
