Hi there,

I got LibreELEC on a RPi1, and, while it's functional, using the extensions or simply navigating folders is painfully slow. It's not unusual for a simple Youtube request to take one or two full minutes. Now, I get it, running a 2017 OS on 2012 hardware is bound to be slow. But switching to a RPi 3 is not an option at the moment due to the high price tag ($50+).

As I understand, LibreELEC was first meant to be stable, and thus does not allow for easy overclocking.

But the slowness…

I attempted to modify the /flash/config.txt following these instructions (meant for OpenELEC, but both systems are quite similar in this regard), trying the "medium" settings, plus some overvoltage so as to allow for more stable operation.

force_turbo=0####################### Overclock mode settings.## default recommended values are: arm_freq | core_freq | sdram_freq | over_voltage# no overclocking : 700 | 250 | 400 | 0# mode 'Modest' : 800 | 300 | 400 | 0# mode 'Medium' : 900 | 333 | 450 | 2# mode 'High' : 950 | 450 | 450 | 6# mode 'Turbo' : 1000 | 500 | 600 | 6# mode 'Pi2' : 1000 | 500 | 500 | 2
arm_freq=900core_freq=333sdram_freq=450over_voltage=2over_voltage_sdram=4

But it doesn't hold after reboot. Although LibreELEC does boot, it appears unable to latch on the network and keep its DHCP-assigned IP (Ethernet, not WiFi). CPU temperature is normal, around 57C with no heatsink under medium load (never goes below 25%), just naturally vented open-top case. Seldom freezes or crashes.

It is currently running off a slightly modified power supply previously used for an old external hard drive. It has both 12V and 5V rail, able to push 2A on both. The 12V rail had no load, and when the RPi is running, a USB voltage/ current monitor records about 180mA drain on the 5V rail, but only 4.64V. When I load the 12V rail with a small 12V LED bulb (around 190mA drain), the 5V climbs to 4.77V, and I can reach 4.85V if I plug a DVD drive (idle). Thus, the 5V real voltage seems dependent of the 12V load.

Is the 5V rail voltage too low to ensure stable operation with overclocking?

What is the maximum real voltage an RPi 1 can take without damage? 5.1V. 5.2V?

Is my /flash/config.txt missing parameters to ensure stable overclocking?

Is the CPU simply too hot at 57C?

Or some other reason why it fails?

Cable. No video is stored on the RPi.

Buffer appears necessary locally as on movie pause, the server hard drives go to sleep after a few minutes, but need time to resume. I just don't like the accelerated or image skipping frames during these few seconds. It reminds me of this pesky bug where a backgrounded video resumes playing while I try to launch another. The main server itself isn't to blame. It can push more than 60MBps from its external HDDs without effort, and I already saw a sustained 88MBps under different conditions. Aggressive standby is necessary because of the noise generated.

The RPi has a good GPU, but still can't handle a 25GB/2 hours of movie over a network. I believe the limit is even lower. It's rather easy to reach its limit. Plus, only the playback is good, navigation in LibreELEC is slow. One must think in advance where he wants to click. I get it, the RPi B was a revolution when it first came out. Still, I can't see any justification to replace the RPi B. This box is rather expensive, and the RPi 3 is even more expensive! I still remember the price I paid 3 years ago for the RPi B: $50 before taxes and shipping, and it was a deal!

Bitrate being variable, buffering larger amounts of data before playing would greatly help those files being played at the limit of what the RPi can do.

And even over the Internet, one has to keep in mind the pipe is relatively small (50Mbps) and gets a lot of use besides Kodi. So, yeah, it can easily stutter on HD video. I think more aggressive buffering would help smooth everything,

Hi again,

I use LibreELEC 8.0.2 stable on a RPi B. Files are spread among 3 NAS using NFS protocol. Most of the time I play 1080p video files that can be pretty heavy, or 1080p streaming from Youtube or others.

I'd like to know if there would be an easy way to manage buffer size so the playback doesn't stutter too much.

Also, what would be an optimal setting for buffer size for all media so it fits entirely in RAM?

Hello there,

not sure if it's a known issue of Kodi or if it's LibreELEC-specific, but here it is.

When I pause a video and put it in background to select a new one, when I select "Play" for the new video stream or file, the backgrounded one resumes. Not a deal-breaker, but nevertheless a bit annoying on my platform: RPi B (1st gen), LibreELEC 8.0.2, Kodi 17

Is it a settings issue or something else?

Hello there,

I've got a Banana Pi M1, and want to compare its performance with the Raspberry Pi when using LibreELEC. The RPi is usable, but rather slow.

However, no official build or generic ARM build of LibreELEC seems to be available for the BPi. So I wrote a Bananian image on an SD card, but how do I install LibreELEC from here?

Strangely, I couldn't find a repository address that could be used with apt-get.

Also, what are the keyboard shortcuts for Kodi?
