Q: Does TriCaster support multi-bitrate streaming profiles?
A: Yes it does, but there are a few things you should consider. Multi-bitrate
encoding places higher demands on system resources than usual. It is entirely
possible to create a custom multi-bitrate profile that is impractical, either because
its bandwidth expectations are unrealistic, or because the encoding requires so
many cpu cycles that it can intrude into other important live functionality.
For this reason, we encourage you to use the profiles supplied with your system
whenever possible, and if you do opt to use a custom profile – especially a multi-
bitrate one – do perform meaningful testing in advance, to ensure everything goes as
planned.
Note: The Stream ID (text string) for multi-bitrate profiles must contain the character
combination
“%i”, without the quotation marks. (The exact position of the character
combination does not matter, and spaces are permitted
– though the latter may pose
issues for some CDNs.)
A multi-bitrate profile without
“%i” in the Stream ID will produce a Flash Media Encoder®
error on attempting to stream. Also, the filename for multi-bitrate streaming recordings
TriCaster saves will automatically
include the requisite “%i” (because the originating
stream ID contains it).

Q: Is it better to use a Baseline or Main profile for H.264 encoding?
A: Flash Media Live Encoder lets you choose either Baseline or Main type profiles
in the Advanced Encoder Settings that opens when you click the Configure (wrench)
button beside the Format menu (in the Video section of FMLE’s Encoding Options
tab).
