Raspberry Pi 3 - Emby Theatre jerky / low fps


Recommended Posts


Hi, I have just installed the latest Emby Theatre iso on a Raspberry Pi 3.


This Raspberry pi 3 has previously been fine operating Kodi (OSMC, Libreelec), and RasPLEX clients. It is connected to the network by Ethernet.

Browsing the menus is very laggy and clunky, and when you try to play (either an HD movie or low-res episode of Peppa Pig), the video playback is so very slow, maybe 3 or 4 frames per second. The low FPS witnessed in the video does resemble the menu issue, so I'm thinking it's a general OS / device issue, ie: not just video playback issue.

The sorry part of this story is that I yesterday also just paid for lifelong Emby Premiere to unlock the playback feature of Emby Theatre for this Raspberry Pi, only to find that it doesn't work. If it remains not working I will ask for a refund as I don't need a premiere account for any other reason.

Please can anyone suggest how to make this work? I raised this issue on github, but thought I may look for a solution form the forum too.

Hi Luke, thanks.. I know with dev work it's like asking how long a piece of sting is, but is there any idea of an expected timescale on this project; or perhaps a better question is the priority it's being given alongside other projects?

Just that my wife is (quite rightly) questioning the ~£80 lifetime premiere investment we have just made for Emby Theatre - it's a bit embarrassing that I can't make it work.

Cheers, Scott

I also am using a Pi 3 as an Emby client, albeit with the Debian image, and I've found that a few changes in the raspi-config really made a difference. You may have already tried these so I apologize if I'm repeating anything.

1. Increase the GPU memory to 128 or 256.

2. Enable the "Fake KMS" driver. To do this go to Advanced Options, GL Driver, enable "Fake KMS". Note, this may kill HDMI audio, but there is a fix for that. You would have to modify the /boot/config.txt file with the below changes, then selecting the second choice for audio in raspi-config (in my case it was MAI PCM i2s-hifi-0).

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes

Hope this helps.
