Ras Pi B performance questions

Hello All,

First of all let me say a BIG THANK YOU for creating Rasplex, I am thoroughly enjoying it!

I currently have it setup on a 16GB SD card plugged into a Pi B (I think). I have it connected via Ethernet cable running through a powerline injector. The problem that I am running into is with 1080P video content. It runs well for about five to ten minutes or so but then begins to stutter every ten seconds or so. I am not sure what could be causing this. Has anyone else seen behaviour like this before? As I was digging through the settings I saw something about a cache file. I moved that up from 5 to 10 thinking that might help the problem. Alas, it did not. Any suggestions?

One other thing that is more of an annoyance rather than a problem. I am currently using the Plex IOS app that has a remote on it. If I press the ‘Home’ button it brings up the menu and allows you to navigate the menu, all while the video is still playing in the background. On the keyboard, you just press the “Tab” button and that brings the video back up. How can one do this on the Plex remote? If it is not possible, I will probably look to purchase one of those fancy remotes with a keyboard on it.

Thank you so very much for all your time and effort into this project!

I have not done that. I will try that tonight! Thank you very much!

Not sure at the moment. I will check when I get home. What class should I have?

Is there a minimum class that is acceptable?

See here RasPlex Installers – RasPlex

Looks like my settings are set to this:

950
450
450
4

And the high settings are recommended to be set to:
950
450
450
6

Do we think it is still this? Or should I just order a class 10 card? I am not sure what I have in there. Not sure if there is a way to check remotely.

Go with the recommended settings, a Class 10 card would be more stable and reliable in the long run. Also make sure you are on the latest version 1.0.0 as a number of fixes regarding stuttering video were included.

OK. I just changed it to the recommended settings for high. I am not sure which version I am on. I ran uname -a and got RasPlex 4.1.10. I did use check for updates through the interface and it said I was on the latest.

You can confirm release in Preferences-System-Updates.

If indeed you are on 0.4.1 you are on a very old release, unfortunately update did not work as expected in that release and was noted in the forum. Suggest that you flash a new card with 1.0.0, you will be amazed at the difference.

OK. I will look at that tonight. My wife just checked and told me that it is a class 10 card. I will give it a try tonight after making those changes. Also, I will check the version as well.

OK. I am on version 1.0.0. I have a class 10 card. I have also set all the settings to the high setting. I am getting a SMALL of lag. I think I can probably live with it. Wonder if I should crank it up to the turbo settings?

Its a 5V 2000mA charger. Is it possible that the Pi 1 B just cannot stream 1080P content direct play?

Yes it can.

I am not sure if I have the B+ or not. This is the one that I have - http://www.alliedelec.com/raspberry-pi-raspberry-pi-model-b/70229569/

Shouldn’t make any difference 512 Model B, B+, or better still RPi2.

Maybe it is a network issue? Is there any way to test the network speed?

Direct Play

@nekoninja:
In an early post you mentioned connecting your Internet cables through powerline injectors, which can sometimes be a problem. The degree of problem depends a lot on the local power wiring. If all power outlets in your home are on the same ‘fuse group’, and fed through the same power meter, then it usually works fine. But when outlets are on different ‘fuse groups’ or on different power meter windings, then there is greater inductance between them, which can reduce network transfer quality. There is also the potential for data packet loss due to powerline voltage spikes caused by various electric hardware.

Even though it may be impractical to permanently replace the powerline usage with direct Ethernet cables, it would nevertheless be interesting to see what results you get with a temporary cable hookup.

Is very likely a network issue, my RPi1 B+ can handle 1080p movies with 25Mbit sustained bitrate on a standard ethernet connection.
