Building a Linux Home Media Center

I realized the best way to connect my digital media library with my home theatre was to build my own Linux home media center (LHMC).'"

  2. When will we not need an MCE box? by dada21 · · Score: 4, Interesting

    I run XPMCE -- yeah, yeah, it works and the WAF is 100%. We continue to try MythTV and various F/OSS programs about 3-4 times a year though.

    But I think I might stop, soon. I already have a decent little file sharing network between myself and about 100 "close" friends. I think we could probably extend this to 1000 people and still keep intruders and others out. I have about a 10mbps pipe at home (beta) that should be available everywhere within a year. One of the providers wants to see it for $19.99 per month (as long as Congress stays out!)

    So that leaves me with my subjust line: when will we not need a dedicated box anymore?

    Bandwidth is almost free, compared to any previous bandwidth before it. 10mbps is just as fast as I can run to the video store and back (depending on the codec used and other parameters, but its close). If I keep maybe 10% of my content on my PC and share it with the 100 out there, I bet we'd have it covered pretty well even considering duplicates for backup. Maybe we need a protocol/program that takes BitTorrent and allows a network of users to safely share video/audio in a wide-area RAID configuration. The other day I lost a CD (AAC's actually, my car stereo supports it) that had about 1000 minutes of music on it. I run my AACs lower than 128kbps for the car. I had the entire set of albums downloaded from a friend in maybe an hour or so, I'd guess.

    The future for me is a system similar to AKIMBO (but open source and needing very little in the way of complex hardware) -- a set top box, maybe 60-100gig hard drive, the ability to copy data to the unit from my workstation, and the ability to set it up in this wide area RAID configuration with my friends.

    True "peer" to "peer" sharing of media, but no complexity needed that is the norm with an MCE -- you don't need terabytes of data, 2-4 tuner cards (my XPMCE has 4: 2 SD and 2 HD) as you can download the shows from BT or whoever else may have the data already, or even a DVD player.

    What would this system be missing? (I just typed as I thought it up, FYI)

      No, it's not because of copyright concerns. It's the fact the MP3 codec is patented by Fraunhofer IIS. Fraunhofer has said they allow people to use implement the playback portions of their patents as long as the resulting program is distributed for free, but this isn't OSI compatible. The free WinAMP player was okay, putting it on a Debian CD which may be sold was not.

      Last time I checked, Windows Media Player supported creating MP3 files

      Last time I chekced WMP was not Free Software. That means (a) it's not legal for you to redistribute WMP, only Microsoft can and (b) Microsoft can (and has) paid for appropriate patent licenses.

      The LAME encoder can still be downloaded freely and plugged into just about anything.

      And the legality of this is questionable, and tricky. Under the "source is speech" argument, it may be that distributing source code is okay. Binary distribution is more problematic, and that's what Linux distros want to do. Distros like Debian, who are very careful about legal issues, find it safest not to distribute encoders (like LAME) at all, and relegate players to "non-free" status, if they're included at all.

      What am I missing here?

      That there are patents on parts of MP3 players and encoders, and those patents create difficulties for Free Software implementations. People may go ahead and do it anyway (similarly, libdvdcss is a circumvention device and is illegal according to the DMCA, but that doesn't stop individuals from using it), but that doesn't mean that people who want to obey the law can do it.

  4. TFA misses a lot. by chrome · · Score: 5, Insightful

    The article spends about 95% of its words talking about how to get that specific hardware working under linux, and then one or two paragraphs actually talking about the interesting stuff - the software that he uses to run the media center. He even neglects to mention how he controls it.

    Isn't there front-ends to make this stuff easier than having a gnome desktop on the TV? What about remote control devices and infra-red support? Is there a nice way to navigate all the media?

    These are the things I couldn't solve easily two years ago ... I'd like to see a decent article that actually covers ALL the aspects of setting up a media PC.

    1. Re:TFA misses a lot. by solarium_rider · · Score: 3, Insightful

      I agree, he spends most the article on how he set up his wireless card and how he set his clock?

      For starters, here's a list of things it would of been nice if he covered if he were to fill us in on the media part(in no particular order):
      * Sound card? Is he using on board sound? Does it support hardware mixing, if not, what kind of software mixing is he using. Does he have a digital connection to his receiver for ac3 passthrough, and pcm output?

      * More information on the video card. He says it supports multiple HD standards, but says it only has a composite and s-video output (i'm assuming in addition to the dvi/vga,) but no component out. How is he gonna output HD then? AFAIK, the nvidia support for HD out requires component out, else you have to set your custom modelines (as the latest nvidia driver 1.0.8178.) While hd output isn't necessary for a home media center I suppose, it increases your geek factor. Is the CPU gonna be fast enough to output 1080i?

      * Power consumption. Would be nice for him to try and reduce the power on the unit, when it's not being used, considering it'll probably be idle most the time.

      * Choice of case for something thats pleasing to the eye, and silent to the ear. Not a big problem if it's tucked away. But usually these things are in the living/family rooms alongside the entertainment center.

      * Controllability: How is he controlling it? x11vnc? Mouse? Keyboard? lirc? What kinds of issues do you run into with these different choices.

      * Software: He spends out two paragraphs on using totem and rhythmbox. How well did these integrate with his media in being able to play everything (other than the spew about OGG and mp3, flac anyone?), why is it important that gstream is uninstalled? Would be nice if he had tried some kind of fully-featured software that plays video and audio...He mentions a 6 in 1 card flash reader...is he using it? If so, with which software?

      Worst LMHC article ever.

      It's based on UPnP AV Mediaserver protocols. There are projects around working on UPnP clients and servers and sample code from Intel for Linux.

      It's complicated to get your head around because of the Jargon used in DLNA but a little effort makes you realise what an elegant, distributed, powerful set-up this is. My favourite part is the proxy media server service that allows a server to also act as the directory listing for ALL servers on the network, providing a simple way to access all media, regardless of location.

  6. Mvix by DrugCheese · · Score: 5, Interesting

    I've been running a linux home entertainment box for a couple years now. I use SuSE ( I think I have Suse 9.3 on there now) and a matrox video card with TV out. My sound I run directly into my stereo system. I use mplayer mostly to play my videos and I still use mp3blaster to play my tunes. Although I have a wireless mouse n keyboard hooked up to it, it's a pain because I still need to get up and turn on the monitor because the text is too hard for me to read on my TV.

    The computer I've been using recently for this task has kind of been overkill so I was happy to find today the Mvix Multimedia Player. As far as I know it runs linux. Just needs a harddrive installed and it's ready to run. I'm thinking of replacing my computer with it so I can use my computer for other tasks (I can always find something). Anyone heard of Mvix before?

      KnoppMyth is not the uber-solution. I have built a KnoppMyth box and while some of the stuff worked out of the box, there were still a lot of things that required tweaking to get right. I had SATA problems, MythTV FULL SCAN problems, PID problems (PID as in DVB provider id), non-existing /usr/local/bin/mplayer, non-functional DVB subtitling etc. And in addition to Myth config, I also had to tweak xine config to get 5.1 passthru.

      While this struggle was not epic (although I did document it in Finnish, 5 pages or so, instead of 1 in the article), I would not call KnoppMyth a SW that you "just drop a CD in the drive and install". But then again, I didn't expect that when deciding that KnoppMyth would be my HTPC SW.

  15. My own HTSRV project status by Xenna · · Score: 5, Informative

    I have had a MythTV box running for a few months (after earlier unsuccessful attempts with freevo and older MythTV versions.

    I boght a Hauppauge PVR350 card (analog TV) and used the "MythTV on Fedora" howto (google) and I was very satified with the results. So satisfied that I bought another Hauppauge PVR500 card so that I ended up with 3 tuners.

    My setup is non-standard for two reasons:

    1. My HTserver (HTSRV) is located in my server room. This considerably improves the WAF and keeps the living room nice and clean and quiet. I transport the A/V signals over CAT5 (using two baluns) to the point where the cable-TV enters the house. There a modulator mixes the signal with the regular cable channels so I can watch my MythTV HTserver's TV-Out anywhere in the house.

    2. Now I needed a way of controlling my MythTV server from behind any of my TV sets. To solve that I used my SqueezeBoxes ( http://www.slimdevices.com/ ). I wrote a Slimserver plugin (Perl) that taps into LIRC and allows me to control the MythTV server with the remotes from the Squeezeboxes.

    I'm thinking of replacing my living room audio system with a pair of powered speakers so that I'll end up with 'just' a TV, a small Squeezebox and two speakers. No 5.1 speaker setups for me, I just can't stand all that clutter. ;)

    There's another interesting project that I plan to look into. It uses Hauppauge's small and inexpensive $69 MediaMVP boxes (miniature diskless computers that run linux with Remotes and TV-Out) to build MythTV and SlimServer frontends:

    http://mvpmc.sourceforge.net/idx.php?pg=main

    This is nice because it allows you to watch different programs & recordings on different TV-sets, which my current setup doesn't allow you to do. Worth looking into if you're interested in a distributed media network rather than just a boring HTPC or HTSRV ;)
