I'm trying to utilize the MPS's ability to use a second encoder for the same conference based on criteria I set (bitrate, best encoder, or best resolution.) After I figured out that you can't utilize the "secondary encoder" feature unless you have "conference self-view" set to "on" (why!?) I ran through some experiments:

I currently have it set to "best bitrate." I connect one system to the conference at 1152k, then a second system at 512k...so far so good, but then I add a third system to the conference at 1152k, and the outgoing video stream to the newly added codec is reduced to that of the system connected at 512k, while the first system I connected at 1152k keeps the higher bandwidth outgoing encoder. Isn't it supposed to function so that systems connecting at the higher bandwidth utilize the higher bandwidth encoder?

Update: If the lowest bandwidth device is the first to connect to the conference, then both devices connecting at 1Mb receive the high-bw outgoing stream...otherwise one of them (the last one to connect) is bumped down to 512.

Update - I must be the only one that's run into this but here's an update anyway:

It's a bug with J4.x Tandberg knows about it now and (hopefully) will have a fix in place for J4.3 - I reverted back to J3.3 and it works like it's supposed to.

excellent find buddy, the old bug hunt :)
