Raspberry Pi - $35 Linux computer

I saw that OpenELEC 5.0 is now released, so I took the plunge and updated. Seemed to work fine, phew!

I have a quick question though. I've started ripping a few Blurays and putting them on my Pi/OE but upon first test they seem to stutter every 10secs or so. I was under the impression the Pi should be able to handle ~20GB uncompressed MKVs from a Bluray? Am I wrong? :confused:

What audio format are you using? The pi can't handle certain ones unless you're using passthru to a AV amp. Without the amp it tries to transcode it as it plays but the pi's cpu can't manage it.

I think I ripped them with whatever's default in MakeMKV. DTS-HD I guess?

I posted the same thing in the XBMC thread in the hifi forum, got this response:

It's the audio, I can play some of my bluray rips as they come from from MakeMKV but some of them I'm having to encode the audio into ac3 and add that to the Mkv as the Pi hasn't got the CPU power to decode DTS-HD and my TV doesn't support pass through

Not sure where to start with re-encoding them.. Handbrake? I really wanted to keep them uncompressed as far as the picture goes anyway.

EDIT: You know what I just checked my recent rips again and I couldn't find any that stutterer. I think I ripped with DTS HD and regular DTS, and possibly even AC3 too so I have all the options..

Media info will show you what format all the tracks are in inside the container.

For re-encoding, handbrake is easiest but it will compress the video and therefore take ages. It doesn't do video passthru.

What you want to do is extract the audio from the container, re-encode that as AAC and put it back in. That way you keep the AC3/DTS whatever else and just add the AAC.

I'm not familiar with a Windows tool that does that. The times I've done it has been with ffmpeg on linux or subler on mac. Googling it now gives this, or this list as possible options to explore. Audio re-encoding will be quick.

Edit: I've read that the Nero AAC codec is good. Details to use it with Hybrid.

I have been using my raspberry pi for a long time now as a media player/streamer for my tv in the living room. it works great most of the time but does slow down and freeze at times. This is why I have decided to get a nuc( celeron) with windows 8 and kodi so i can access skyplayer and other hd streams etc.
 
I gave OpenELEC 5.0 a try over the weekend... seems alright so far

Although like others I do still sometimes get freezes for which the only fix is a total reboot, sometimes while watching things but also when in the menus... I also find that when playing back larger high-quality files trying to do anything (even simply pause and un-pause) is super slow and unstable... I was previously also using the "high" (but not turbo) overclock setting, which I noticed made scraping for metadata way quicker - and seemed to help a bit overall too

However I got a new TV at the weekend as well and that seems to have messed everything up, much more freezing and issues. That's what prompted me to install 5.0 and touch wood it seems to be working okay so far (I haven't re-applied the overclock)... But I'm starting to consider whether or not to upgrade to something else also

Doesn't help that my pi is an original 256MB B... so my options are to buy a B+ and see how it goes... or maybe a Cubox-i2 or i4 I'm really not sure (clearly the B+ is cheaper but I'd rather not get it if it's not going to be any better)
 
Has anyone used a Petrock SNES GPIO adapter on here?

Got one on order with a view to breathing some RetroPi life into a dead SNES I've got a home, wanting to keep as much stock as possible so will be using SNES controllers etc.

One thing I'm struggling to find is a microUSB male/female with flush panel fittings in this country. I could adapt to USB A but I'd only have to adapt on the power side again. Failing that, I might reutilise the SNES's power jack and get a 5V PSU then make up a jack to MicroUSB cable.

Have got HDMI, Ethernet and USB panel fits on the way for the other ports along with the GPIO adapter so shouldn't be too long before the dremel and soldering iron comes out to play. :)
 
I'm considering hooking my dvb-t2 nanostick 290e up to one of my Pi running raspbmc rather than use my pc to record the rare things i actually want to record live.

Has anyone done this and does it work OK?

Ideally I'd want to stream the recording to a nas. I wonder if that is even possible.
 
Has anyone tried using Limelight (NVIDIA gamestream client) on their Pi?

I have set it up, but performance isn't great. I might need to overlock my Pi to the highest setting and check that my network is holding up (using home plugs and I'm not sure the wiring in my house is great).

I might also try a fresh install, I do have things like a web server installed on it currently as well.
 
I'm running limelight on my pi. I've got an old model b but I've overclocked it to high. I find the performance is great, I did build my own fixed point opus, this helped greatly with sound stuttering.
I'm streaming at 1080p and find over 5ghz wireless
Is virtually flawless.
Played grid, pes, far cry 4, etc and all play fine.
Im also using a xbox wireless controller that's plugged
Into my PC, using one plugged into the Pi does cause problems.
 
I'd just like to say, I love being in this community.

Limelight sounds fantastic and for me essentially means I could hook up my tiny little RPi to the back of the plasma and play games with my 360 controller while the PC remains in another room without a single cable between the two.

There's no extra processing power or memory in B+ so you wouldn't see a blink of change other than random install quality.

'B+' is more power efficient because they were using liner power supply circuits in 'B' and replaced them with switch mode power supplies to power the entire board.

The difference between the two is essentially; switch mode flicks the power on and off and uses components (capacitors and inductors) to hold the charge so it can supply power in those moments when the power source is switched off.... linear power is just always on. That's how they made B+ more efficient by turning it off for half the time. Haha! :)

So if you need more processing power you should look elsewhere.

Edit: I'm sorry, I just took a little peek to be sure and found that very early Model B revisions used to be 256MB and then they switched it to 512MB but kept the same name.

Goodness me! Why do you ALWAYS deliver Bledd?

That's an incredible amount of extras on the same size board... PICe mini, mSATA, S/Pdif, reset switch, WiFi (!!!), 1GHz dual core, 1GB RAM, IR receiver, bluetooth and even runs Android 4.4.2 or Linux.

This is ridiculous! I feel like this would be used more as a system than for development, especially if it doesn't grow popularity/support. I can just imagine installing a TVMC apk or PLEX apk and Bob's your uncle.

Shame it costs triple the price of an RPi for all those features (I didn't find that out till the end) but the lowest end model is $10 more than an RPi and is essentially the RPi with an extra 300 MHz.

I've been using my B+ to stream contents from my pc to the kitchen tv via openelec.
And as many of you know this requires the pc to be on at all times if I want to stream.
Now I'm wondering, is it possible to hook up an external hdd onto the pi and just transfer content from my pc to the hdd without removing the external hdd on the pi?

I guess what I'm trying to do is copy content from the pc onto the external hdd connected to the pi, and stream/play the content from the hdd with the PC turned off?
Copying files would be done wirelessly.

Should work fine. Will be a bit slow to copy wirelessly, but not too much of an issue.

I have a similar setup except my Pi talks to my NAS. The only difference in your setup is that you would be connected to your content drive via USB rather than network.

OpenElec is very good at picking up drives, so it should just pop up when connected.
