I’m trying to build a Raspberry PI 3 B+ dedicated to
Mythth-frontend. I’m close to where I need to be, but years
of working on selling CPUs into GFX and Video applications
makes me hyper sensitive to minor video issues. I think it’s a
curse in this case.

<div class="">Giving 256MB of RAM to the GPU limits you some.
Things I noticed that surprised me a little.</div>
<div class=""><br class="">
</div>
<div class="">1. If I have Raspbian Lite, Xserver, XFCE, and
lightdm with Mythtv-frontend, Mybuntu 28.21 theme and an
HDTV recording playing I have 35 MB of memory free with no
Swap used. Here I launched mythfrontend after setting
performance mode on scaling governor. </div>
<div class=""><br class="">
</div>
<div class="">2. If I only install xserver, matchbox window
manager, lightdm with the Mythtv stuff as #1 I also have 35
MB free</div>
<div class=""><br class="">
</div>
<div class="">3. Using Openbox instead of Matchbox the same 35
MB free.</div>
<div class=""><br class="">
</div>
<div class="">Both 2 and 3 autolaunch and autologin per the
Mythtv RPI wiki</div>
<div class=""><br class="">
</div>
<div class="">4. If I change the theme to the Default Mythtv
1.4/7 one, then I have 122 MB free.</div>
<div class=""><br class="">
</div>
<div class="">5. FE locked up if I tried to run the Xmas
theme. I imagine it has the largest memory load.</div>
<div class=""><br class="">
</div>
<div class="">In either case the video performance is the
same. Basically the video is great if the motion is not too
fast. quick panning is jumpy.</div>
<div class=""><br class="">
</div>
<div class="">I basically followed the tips from the Mythtv
Raspberry pi wiki.</div>
<div class=""><br class="">
</div>
<div class="">Anything else I can try?</div>
<div class=""><br class="">
</div>
<div class="">My goal is to use the RP3B+ as my frontend
without having to use Kodi 18. The video performance of Kodi
18 on RP3 is very good compared to Mythtv FE, but the Kodi
interface is not to my liking.</div>
<div class=""><br class="">
</div>
<div class="">I have a NUC Core i3 running Xubuntu with Mythtv
FE on it and it works perfectly, but I need the NUC else
where.</div>
<div class=""><br class="">
</div>
<div class="">BTW, I tested the Kodi 18rc on the NUC and it’s
video is not as good as 17.6 and when it was installed it
messed up the Mythtv FE. I had to uninstall Kodi 18rc to get
Mythtv FE back to normal. The only way I could see the video
issue was to watch a news crawl across the bottom of the
screen. </div>

<p>I find the panning judder on the pi with myth 29 unacceptable
at 1280i. Version 30 pre is an improvement with the new sync
mechanism and I find 720i acceptable on a 32ins TV. Kodi gives
perfect pictures at 1280 if you are ok with the interface.
Using Rasbian out of the box with 256m screen memory and
Steppes theme not suffering memory issues,<br>
</p>
<p>The Firestick 4K is a game changer with picture quality as
good as Nvidia. It is not however currently reliable enough
for production use,<br>
</p>
<p>The Firestick 4K is much bett<br>

<p>Interesting feedback. I have 3 questions:</p>
<p>1. Are we talking about this Firestick 4K?

<p>2. Will the ethernet adapter I use on my non-4k version of the
Fire Stick work on the new 4K version?<br>
</p>
<p>3. Will Version 30 Pre Frontend on RP3 server video from my
29.1 backend?</p>

<p>1/ Are we talking about this Firestick 4K? yes</p>
<p>2. Will the ethernet adapter I use on my non-4k version of the
Fire Stick work on the new 4K version? I think so Amazon list. Yes
according to "Amazon Ethernet Adaptor for Fire TV and Fire TV
Stick with Alexa Voice Remote (2017 models), Fire TV Basic Edition
and Fire TV Stick 4K ?"</p>
<p>3/ Will Version 30 Pre Frontend on RP3 server video from my 29.1
backend? Yes amazingly so<span class="moz-smiley-s1"><span>:-)</span></span><br>
