SPEED TESTS
Are you sure your upload bandwidth is adequate to the bitrate you’ve set for your stream? Why
not test and make sure. Again, a number of websites provide free speed testing. These will give
you a basic idea of what your local bandwidth really is. One site which provides a list of online
speed test resources is: http://www.dslreports.com/speedtest?more=1
IS IT REALLY A TRICASTER ISSUE? 15.8.2
With regard to streaming issues, don’t overlook the fact that TriCaster is just one of the pieces of
the puzzle. There are many others that are just as important. Here are some useful things to try:
CHECK THE FILE
Archive the streaming output file locally, and then examine it to see if it has any problems. This
file corresponds exactly to what TriCaster is sending the downstream server. In cases of sync
problems, low frame-rate problems, audio popping problems, etc., if it's a TriCaster issue, the
problem will be seen in this file. On the other hand (if the file looks good), then the issue has to
be up-stream of the TriCaster.
DROPPED FRAMES
To really confirm that TriCaster is outputting the frame-rate you chose (i.e., not dropping frames)
you can edit a profile inside Flash® to cause FMLE to write out frame-rate stats. These settings
apply when using the TriCaster, which lets you verify that it is uploading the stream at the rate
designated. (In FMLE, select the Encoding tab, and check mark "Log To File").
