The FMLE statistics tab did not show anything during the upload.
What is the recommendation? To drop frames OR degrade quality?
If B, then what settings should I choose for buffer length?
Also check to see if the encoder is buffering the video or dropping frames. It may be buffering a few seconds every so often and when you stop the encoder at the end of the event, it hasn't sent it all to Wowza. There is a setting in fmle to either drop frames or reduce quality if it is going to buffer more than a certain amount so that it doesn't get too far behind. If it drops frames then these don't get sent so don't get recorded. The will probably get recorded locally though.
You can see what fmle is doing from the log tab and then the statistics tab on the right.
