Installation issues / Re: DVD install MCE810 dvd hangs on first step!
« on: January 18, 2012, 07:54:00 am »
OK, tried next latest snapshot: 25224 and pretty much the same error except it doesn't even get to the initramfs stage, just dies shortly after the sliding bar. I see the snapshot overview wiki - http://wiki.linuxmce.org/index.php/Snapshot_overview has only older snapshots that aren't on http://linuxmce.iptp.org/snapshots/

Is there somewhere I can find those older, verified snapshots?

Options still to try-

1. Try to add another graphics card (first need to bend the arm of the h/w supplier to void my warranty when I open the box)
2. Try internet install - kubuntu first then, internet
3. Try one of the older verified snapshots if I can find them
4. Try 10.04  :o

Thanks for the quick reply.

Will try install on another pc... in the meantime I'm tinkering with the BIOS onboard vid setup. When I changed it from PEG/IGD to IGD things got marginally further- the scrolling graphics bar disappeared to be replaced by a prompt (initramfs) I think. Don't know if that means anything to anyone but it does make me suspect the video card could be part of the problem.

Could also look at 10.04 but I'm such a newbie, wanted to go for the tried and tested.

This is just sad! I finally get to trying an install on my new hardware for my new core and I don't even get past step 1!

Basically I downloaded the http://linuxmce.iptp.org/release/LinuxMCE-8.10-final.iso image, verify MD5 checksum and burn image to DVD. Then I boot DVD on my new hardware and get to the Menu screen (Linux MCE, Install Kubuntu, Test CD etc) but whatever option I choose from there, I get the KUBUNTU plus scrolling bar for about 40 secs after which that disappears and the screen goes to sleep.

Have just, this morning, on the same machine, installed Fedora 16 with no issues at all from bootable DVD so the DVD drive seems to be working and no other major issues with hardware.

Where do I start trouble-shooting this?

Firstly, I booted the dvd on my laptop and tried the kubuntu live and it worked fine so the burn appears to be ok. Obviously some combination between this image/ software and my new hardware?

Now I'm busy downloading the latest snapshot LinuxMCE-8.10-25224-i386.iso hoping that will somehow be different. I can also try the internet install method.

Any other suggestions?

My hardware:

Motherboard: FOXCONN H61MX-V DDR3 LGA1155 M
CPU: INTEL CORE I5 2400 3.1GHZ SKT
RAM: 2x KINGSTON DDR3 4GB 1333 DESKTOP
HDD: SEAGATE 2TB SATA 3.0 3.5" 5900
DVD: SONY +/- DVD WRITER 24+R,SATA
EXTRA NIC: ZYXEL PCI GIGABIT ETHERNET CAR

Yes, I know, onboard graphics is not Nvidia... not sure what it is actually or how to find out but the place that built it had some issues putting in the cheaper Nvidia cards. Apparently motherboard threw errors. They reckoned the cheapest that would work was pretty expensive and would require a PSU upgrade. I thought I'd leave that and see if I could just get the install done... after all, this is ultimately supposed to be a headless core. Could the onboard graphics be the problem? Even at this stage of the install? Otherwise, how do I get to the bottom of it?

Any suggestions welcome.

Installation issues / Re: Media Director with video capture
« on: January 09, 2012, 10:53:09 am »
Hi Tony

Thanks again for the informative feedback. My current DSTV setup is as follows-

I have the SD dual-view PVR decoder which only does standard definition channels but has built-in PVR and dual-view functionality. The Dual-View means that (as I understand it) the decoder can output two simulataneous channels. It does this by sending output on the RF-OUT on two different frequencies. So you can connect TVs to the TV-OUT and either tune them to frequency #1 (and get whatever channel is selected there) or frequency #2 ( and get whatever channel is selected there). There are actually two coax outputs, labelled TV1 and TV2 respectively but I think they probably do much the same thing... it just means you don't have to have a splitter.

For control of the two streams, you use IR remotes and just flip them to a different (freq?) to control the different streams. On the tenant side, there is an IR "eye' connected inline on the coax cable which somehow allows the decoder to pick up IR signals encoded onto the coax coming back to the system. So you can point either remote at either the decoder itself or the "eye" and, depending which "freq" on the remote is selected, control one or the other stream. Then you can see either stream from either RF-OUT if you tune to the appropriate channel.

Either stream can watch channels or control the PVR so both can watch and record movies as well. The problem comes in, naturally, because you can delete each other's recordings.... grrr.

Now... if I am understanding correctly, you are saying that MythTV embedded in LMCE could effectively replace my entire system? In other words I'd (THEORETICALLY) be able to plug the coax input(s) from the LNBs on my sat dish directly into a tv-tuner card in my core, plug my subscriber DSTV smart-card into some kind of card-reader and then install and set-up software to magically combine the two to send channels of my selection to any media director on the system?

That *must* be taking it a bit far, surely?

Tony

Thanks for the detailed and informative response. Definitely some food for thought there.

The reason I was concerned about bandwidth was that prior to setting up MCE for myself, I've been using the LTSP (k12 Linux) to serve my FC13 installation to thin-clients (old, pxe-boot diskless laptops) at my various network points. By doing this I've been able to play music at least at various nodes in the house as well as any other normal computer tasks I need to do. It's pretty cool for a start but I've noticed the video is really slow. I assume the reasons are that
a) The clients have 10/100 (maybe even just 10 Mbs) LAN cards
b) I don't have a network switch yet and I'm making do with an old 10/100 hub
c) I suspect the clients are very thin  ;)  ... in that I'm not 100% sure how LTSP does it's processing but I presume it is almost a case of the server running the application and only the graphics stuff being rendered by the client... sort of like remote X.... if so, my understanding of the Linux MCE Media Director is that it is a rather "thicker" client in that the media applications will run on the client as well as the graphic server, video and audio decoding etc with just the raw (usually compressed) data being passed from the server down the network.

Whatever the case, your response has made me confident that when I put the Gig switch in and ensure all internal devices have Gig cards... things should be good.

In terms of the two manners in which TV signal can be captured, that is most interesting. Certainly, as you say, the method of capturing the raw satellite signal and then decoding it in software is very appealing and elegant. And, as you point out, there is more potential there.... however, in my case I think I'll have to start with the alternative- capture the video output itself from the satellite decoder. The reasons are-
1) The provider is a pay provider with a "smart" card which would involve the card reader part that you refer to. Not impossible, as you say, but some extra effort and research required.
2) I'm based in South Africa and I don't think there are many here who have gone this route before me so support and assistance from the community regarding the particulars of our local Sat-tv provider are going to be rather scarce... not to mention the fact that I'm sure their programming schedule is not available electronically.
3) The local provider is not that fantastic ito options  :'( so I don't often find there is a situation where I can find more than one channel at a time I want to watch!
4) My current decoder does already have some fairly neat PVR and dual-view functionality built in which means that I'm already serving an alternative stream to my tenant (in a flatlet on the property) and I'm able to schedule and record already via the PVR. If I implented soln 2 that would basically replace this fuctionality but.... I'd have to give my tenant access to my MCE installation. I think that can happen further down the line. Perhaps when my current (old) PVR packs up and I'm forced to upgrade... I could potentially just use MCE instead of a new decoder?? Exciting future ahead.

Many thanks againf or the comments and assistance.

Installation issues / Media Director with video capture
« on: January 06, 2012, 01:35:29 pm »
Hi Everyone

Some advice please- I believe the recommendation is to put the video capture card into the core. My planned layout at present (I'm planning the system but have already done most of the network wiring) has the core sitting in the closet with the Gig switch and ADSL modem but a long way from the satellite decoder.

My plan was to have a media director in the TV room with the capture card, then the output from the satellite decoder would be fed to the MD capture card and presumably magically through to the core for redistribution / recording etc.

Firstly, is this possible or does the capture card have to be on the core?

And, if so, what are the issues going to be? The most obvious to me seem to be that if you're capturing video directly to the core you don't use bandwidth on the network line between core and switch... the capture input arrives via the PCI bus instead. So any time video is captured it's narrowing the bottleneck to the core. Are there other factors?

I'm trying to think why I don't want the core in the TV room..... apart from noise and space.... when I remember the reason, I'll post back.

Thanks for the feedback, guys.

I think I was a bit confused about the internal MCE network. I was under the impression that all machines plugged into it had to either be the core or a media director so I was wondering where my existing workstation fitted in. As I now understand it, I can plug my existing workstation into the MCE internal network and MCE will just see it as a file server... I can continue to use it as normal, access the internet and possibly some other shared resources on the network without making it a core or Media director. I gather if I want to run it as a media director I can either dual boot it to PXE or run a virtual machine on it with the media director on that.

Ah, I think that answers my question, thanks!

It frees me up to go and search for the ultimate super-cheap and super powerful core. Yay, hardware shopping.

Also, I finally managed to indoctrinate my wife with all the pro-linux sentiment and she really has the hang of Fedora so if she can carry on working merrily on the workstation in a distro and systems she's familiar with while I tinker with MCE that will help a stack.

Thanks BW.

Hi David

Did you ever make any progress on this one? What was your final decision? I'm grappling with similar issues- do I make my existing workstation a core or should I set up an entirely separate core so I can tinker/ develop/ do other stuff on the workstation.

I'd be interested to hear where you are with this now.

thanks
James

That's interesting... I guess I thougt the workstation would have to be an MD because I figured it will be plugged into the MCE network and if something is plugged into that, doesn't it have to be a media director or an orbiter or some MCE component? Especially if you want to potentially access some of the resources?

Running the MD in a virtualbox on your workstation is an interesting idea. Presumably your workstation is connected to the MCE network then?

I should possibly go and have a look at some of the setups on the FAQ pages and see if people have done similar things.

Just found this other thread which hits some of the issues I was asking about:

http://forum.linuxmce.org/index.php?topic=2406.0

Thanks for the response, BW.

From reading these responses, it sounds to me as if my core should be a dedicated machine that I build for that purpose- so I don't sit down at that one to check my mail, I sit down at the core to set things up in MCE etc etc.

For my desktop computing, I should use a media director, but one that is decently spec'd so it can run all the "office type" apps and things I want to do. The only difference between it and a normal desktop linux machine (my current setup) will be that it will pxe boot and use the HDD attached to the core (although it could use its own as well?)

Here're my thoughts, if someone cares to comment, I'd appreciate it:

My current machine (FC13 installation) is a Dell dual core pentium with about 300Gb HDD and a video card and 2x NICs that seem to be compatible with LinuxMCE (from my first installation attempts).

I was planning to turn this into the core/hybrid and then build media directors as required as I expand my MCE empire. But then I was imagining using the core to do my computing tasks - check mail, balance my finances, plan world domination etc.

Now I'm thinking I should build a dedicated core machine that runs the whole time, has all the supported h/w and is used primarily for setting up and administering MCE. Then just plug in my Dell desktop and let the DCErouter set it up as a media director (pxe boot). Then I can use it's reasonable resources to do my desktop computing as normal and also use it to show / drive media if necessary but if I'm doing desktop stuff it won't be hampered by the core resource load which will be handled by DCErouter.

I guess I could even leave the FC13 installation on there if I wanted with a dual boot option and/or access the storage on the hard drive either from FC13 when I boot to that or make the same storage available to the MCEnetwork?

Feel free to comment/ advise/ criticise.

Hi All

Sorry if I'm posting in the wrong forum, please advise if so.

Obviously the MCE project is all about home automation and media serving but I was just wondering if someone could advise where the normal desktop computing part fits in best. I've experimented a bit with MCE and I'm keen to try it properly once construction on my home is complete but currently I'm just using my machine as a stand-alone desktop computer (fedora 13) to do the normal stuff - intenet, e-mail, office stuff etc.

When I go to MCE, at present my plan will be to use this machine as the core/hybrid. Where would the desktop computing aspect come in? Would I use the kubuntu stuff on the core/hybrid and just serve that to media directors which become terminals? Or should I have a separate machine to do this stuff and just connect it up to the MCE network to share drives and other resources?

I realise the project is obviously focussed around home automation but I just wondered where /how best to integrate the normal existing computing aspects while I experiment and learn with this exciting concept.

thanks in advance, and sorry for the clueless newbie question.

Thanks for the link Kramden. Tried those steps from the thread (re-install of radeon drivers) but still no dice- same results on boot of MD.

Will have to dig a bit further into the logs. My strategy remains to try to get an appropriate xorg file for the MD and get it to read that when it boots up, rather than the default which overwrites each time.

I'm having issues with getting X working on an MD (see http://forum.linuxmce.org/index.php?topic=10720.0) and am also heading towards the sort-X-out-first approach of Kevin below. His was on the core, whereas mine is on an MD and what I'm struggling with at the moment is getting the relevant xorg.conf file to be used... as you will see from my post, in my situation, stopping Xconfigure.sh from changing the file isn't enough... once I've done that, somewhere in the reboot the xorg.conf file seems to be deleted and then the X-server startup is falling back on some default settings.

May not be a problem for you but something to watch out for.

Thanks for the link Zaerc.

Still tinkering through but it's getting late and I need my beauty sleep. What I have discovered is how to stop the relevant xorg.conf.pluto.avwizard file being overwritten every time the MD boots up... sounds like a no-brainer in the wiki - force exit from usr/pluto/bin/XConfigure.sh but you have to get the *right* Xconfigure.sh- there is one for the relevant MD as well in /usr/pluto/diskless/XX/usr/pluto/binXConfigure.sh !! (where XX is your MD number).

However, it still isn't quite right... seems now to be deleting my customised xorg.conf.pluto.avwizard when the MD boots (rather than overwriting) and then falling back to some defualt settings. Hmmm....

Anyway, I'll tinker more when I get more time.
