Plex will use HW encoding, even with the minimal GPU driver installed. 

REALLY?

Yes, REALLY.

I did my testing while logged in at the console, not RDP.

I'm afraid, that's not what I meant

What I meant was that I got some doubts about whether Plex would be able to do hw transcoding in the exact same situation.

Can you try playing something back in Plex then posting the ffmpeg command line used from their log file?

Plex doesn't use FFmpeg, and I couldn't find the parameters used for their own transcoder, but I did find this:

Yes they do. Those are all components of ffmpeg you see in those log lines there.

Oh yes, they to. The executable has just a different name.

They are using Windows Media Foundation for encoding, what we don't do - so you're right and they are in fact able to do hw encoding while we can't (inside service and or RDP).

Though I need to say that this is the first time in years that I'm seeing such situation....
(just a little anomaly in the statistics...)

Right - they might use it but it is not visible to the user.  Maybe it is just under a diff name.

Plex Transcoder.exe = ffmpeg.exe

Plex Transcoder.exe = ffmpeg.exe

I didn't know their EXE was just FFmpeg (and maybe it is not just FFmpeg, I don't know ).

I did find the params:

OK.  So, Emby has no solution for me now and no expected solution in the future - is that a correct assessment?

Just to summarize the situation:
I do have D3D11, tested at the console (so monitor is online ), Plex is doing something different and able to use HW encoding.

Without RDP and without running Emby as service but starting normally, what hw codecs to you see in Emby?

The same as shown above.

[softworkz 5066]

OK, then it's probably really the driver being to old. I'm afraid that I don't have any better news.

Could you possibly replace your $5 CPU with a  $10 CPU (slightly newer)? I don't know your motherboard..

[justinrh 260]

Not really.  There wouldn't be a better iGPU for my MB, and CPUs for it are hard to find anyway.  I'd have to upgrade the system or add a GPU, which I'm reluctant to do because I want to keep the thermal load down.

I appreciate everyone's help.

Well...  I got an answer as to why I don't get HWA.  So, I reluctantly answer 'yes', Luke.  I'd like to have found a way to get HWA working

I marked softworkz's post as an answer.

Well you can, just outside from RDP, right?

Nope.  I'm told my hardware is not appropriate for Emby to support it.  But that other media server can, so I was surprised Emby wouldn't.

correction:  added the 'not' for appropriate!

Yea, that's the one-in-a-million case, I'm afraid. Normally, it's the other way round.
