Please attach the emby server log. I just tested and it seems to be working just fine.

here's the log with throttle enabled in transcoding section

Does this only happen on transcoded hevc content?  But to me it looks like the system can not keep up as there are a couple ThrottleBuffer in the log.

here's a log of a transcode from an XVID file.. Attached File  ffmpeg-transcode-ef3f9578-f122-4c92-9e75-32126c64cb60_1.txt   48KB   1 downloads

I started plya the file and pressed pause..

at the beginning emby says throttle off: Attached File  2020-04-08_090943.jpg   33.5KB   2 downloads

 

after a while throttle is active: Attached File  2020-04-08_090957.jpg   33.7KB   2 downloads

 

I made the same test with the movie HEVC and throttle remains off at the beginning: Attached File  2020-04-08_091245.jpg   30.18KB   2 downloads

The throttle stays off until the buffer is filled and only then it activates the throttle.

So, until the buffer isn't filled the throttle will stay off in the dashboard.

Depending on the transcoding speed this happens quite fast or takes some time.

 

Looking at the snippet in Happy2Play's post, it would probably take a while for that file as it is transcoding slower than realtime speed (speed <1).

 

From your screenshots everything looks normal to me.

because when starting playing a movie I always see throttle off.

After a while I noticed that throttle became ON and @neik explained me why..
