(I'd somewhat highjacked someone else's thread on transcoding. I'll leave theirs be and start this new one.)
I had confusing experiences with Emby's transcoding. I did some intentional tests and better understand what's happening. These aren't bug reports. But I'm looking for more insights on how to best use Emby and ideally be able to live transcode content instead of having duplicate pre-transcoded copies.
My system:
Emby Premiere (3.2.9.0 during testing)
ffmpeg is March 10, 2016 (I think) (installed by Emby into the Emby folders, I believe)
Skylake i5 3.2 GHz (6th Gen 6500)
Intel Graphics HD 530
Windows 10
Connected by 100Mbps switch to 1Gpbs LAN
Testing by streaming to a 4th Gen AppleTV connected to the same 100Mbps switch running tvOS Emby
