Emby Theater stuttering on 1080p content

Set Hardware Acceleration to auto, and try again.

 

Luke, auto should be the default setting on that. None, is what they recommend, but many people won't have CPUs that can handle it. And also, none when using mpv doesn't also have to run the resources that Theater uses. You'd need a substantial CPU for that.

Hello, I am having an issue with the Theater desktop app. For most hd content I try to play, it stutters at first and sometimes smooths out but usually stutters intermittently. I can see its direct playing from the server. I play the same content through firefox and get no stuttering. I really love the desktop app but have issues playing hd content.

 

For the client I'm running Emby Theater 3.0.5

Windows 10 HP Desktop with 6 GB system ram

AMD Athlon 64 X2 Dual core 4400+

AMD Radeon R9 270x 2GB graphics card

 

And the server is Ubuntu 16.04 running emby 3.5.3.0

AMD FX 8350 8-Core with 24 GB system ram

AMD Radeon R9 270x 2GB graphics card

 

Both connected to 1Gb Ethernet LAN

 

I can access the files directly through samba shares that are setup on the server.

 

I have also tried to play some 4k content but it stutters even worse. The only difference is that it doesn't play any better through the browser.

As far as the 4k is concerned what is the bottleneck, is my hardware just not good enough?

 

Thanks for any and all advice.

If it's direct playing, why are there remux logs? And what audio and video settings are you using?

It was direct streaming from the browser, it only direct played with theater. I had it set to auto.

You have what set to auto? Can you post a screenshot of your audio and video settings in Theater?

No, not that. Have you not looked in settings? Top right corner, click on the user icon next to the clock, and go to settings.

Also, are you using a receiver with HDMI?

That worked, thanks! However the 4k videos still stutter tremendously, I even tried to setting the quality to 1080P but didn't help.

Yeah, I imagine your 4k stuff is HDR? mpv tonemaps HDR and renders it to the video. That takes a little more processing. Press ctrl+j when you're watching a 4k. Look at the stats. Is it dropping frames? And if you have a 4k SDR movie, try playing that, and see what happens.

Yeah its HDR, and yeah its dropping frames like crazy. Is the client cpu the sole bottleneck? I was thinking of buying an nvidia shield tv.

I have a mini PC I was testing with. It has more resources than yours, and it too was dropping frames with HDR. It's a combination of GPU and CPU. And in with these little units, the CPU just can't keep up. Maybe it'll be more efficient in the future? A shield would be able to play them, it doesn't tonemap. Te emby app does at present have an issue playing cropped HDR videos. The other thing you could try is using an external player like MPC-BE with madVR. That can pass the metadata to your display, and should require less processing. 

 

You have an HDR display, correct?

I just tried a non HDR 4k video and it still drops a lot of frames as well.

Oh, so you're downscaling. Well that will add to the load.

Is there even that much HDR content that's not 4k?

Not that I've found.

 

You should try using MPC-BE with madVR. It might just get you where want to be, for your HDR stuff. It takes a bit of configuring, though.

Is that setup through the external player setting in Theater?

Yes. You can use any player you want, MPC-BE with madVR would be what I suggest. There are a few recent threads about doing that.
