<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">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=""><br class=""></div><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><div class=""><br class=""></div><div class="">Jim A</div><div class=""><br class=""></div><div class=""><div class=""><div style="color: rgb(0, 0, 0); letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><br class=""></div>
