htpc guy Wrote:Wow. You said it. Lazy sums it up. 2 seconds of Google Foo will give you the answer.
And it took you 5 seconds to reply with a funny but not informative answer. A "Yes" or "No" would have done.
As for using google to find if the R-Pi can run 1080P video. Well I have not seen the info I asked for. And that is, Would the R-Pi be able to play a 1080P Blu-Ray rip .MKV file? This also means that it would have the DTS-HDMA or DD-THD sound at 5.1 or 6.1 (like Star Wars) or (as some of my movies have DTS-HDMA) 7.1 surround sound.
When it comes to this neat bit of kit. I Am hearing/reading how great it is. But nobody is giving simple answers. It's all Tecno babble numbers and stuff.
so as my Google foo is poor. Help a noob out

XBMC doesn't support HD audio no matter what the platform - until the AudioEngine update is released, XBMC will extract core audio only.
Whether R-Pi will support MKV, Blu-Ray, DD/DTS (and eventually, HD audio) remains to be seen as that information hasn't been announced - we're waiting on Eben (one of the Foundation founders) to post a blog article detailing what codecs (video and hopefully audio) will be supported. The only confirmed video codec is h264, beyond that is anyones guess.
EDIT: Maybe not the post we were expecting from Eben, but this post just appeared which may give some detail/background on codecs.

We are all making a fuss about HD videos and we already know that they are supported. But what about normal XviD videos? In their latest blog post, it is said that they will not be accelerated.

Really? Seems odd that my Star Wars movies play in full 6.1 And my Transformers and some of my Disney movies that are 7.1 render sound to all my of my 7.1 analog speakers system from my X-fi titanium card. This is new as it did not before Eden.
But as the R-Pi is HDMI. If you was to have a Digital AV receiver with HDMI. Then I have a feeling that you would get DTS-HDMA as the decoding for that is done there and not with in XBMC. I My be very VERY wrong on this. I Don't have a Digital AV receiver to test

From the comments in the aforementioned blog post:

You say that MPEG4 and H.264 will be supported. In fact, H.264 is MPEG4 Part 10. So what do you mean by MPEG4? Is it Part 2?
Also you say that there are only these two at this stage. Is it going to be possible to somehow upgrade the existing device? Is it just software thing?

Yes, it's just a software thing. Hopefully more codecs wwill be added at a later date. There may even be a pay for licecned codecs option – see Liz's post below.
I've quoted the two Codecs as often they are regarded as separate by the end user who have filenames like fred.mp4, or barney.h264, but you are correct, H264 is an MPEG4 part 10, MPEG4 is part 2 (H263)

Would it be possible to purchase extra codecs separately ? Like having a firmware update. I've seen it on some tablets (Archos), the device is shipped with some default codecs, and if you want others you need to purchase codecs separately.

This is an option we're looking at exploring. If we do decide to go down that road, it won't be for a few months; administratively, it's hard to manage, we'd need to see a clear benefit for the charity, and it'll require another round of talking to the MPEG LA (and another round of form filling; the back and forth took about a month last time).
So there you have it - H264 and MPEG4 part 2 only for now, with the possibility of more hardware accelerated codecs in the future at additional cost.
It seems the R-Pi could fall short in terms of supporting all of the codecs one normally expects from XBMC, but maybe the situation will improve with time (and money).

There are ways and means to get XBMC to handle HD audio, but an out of the box and unmodified install of XBMC doesn't yet support HD audio (DTS HD-MA DD TrueHD). As such, I doubt the R-Pi build of XBMC will either.

davilla, I don't know if you are permitted to answer this but, can the Raspberry Pi handle XBMC and XviD with no problems since there are no acceleration for it?

This may be of interest to some of you out there (from the aforementioned blog post):

How about on the pure audio side of things? FLAC, Vorbis and Speex should be no problem. Isn’t the MP3 decoder free as well?

Audio is all done on the Arm, so whatever codecs you can get your hands on.

The post was amended, the mention of Xvid as not hw-accelerated was a misunderstanding. The new version of the post says only that MPEG-2 and VC-1 aren't supported in hardware.
Dom (I understand that he is a member of the foundation or an engineer working on the board) clarified it in a post in the forum:
Quote:[Xvid/DivX] follow the mpeg4 standard and our mpeg4 decoder will play these happily.
Quote:Xvid is not a codec, but an implmentation of mpeg4 part2, and we support it.

Too bad MPEG-2 isn't accelerated, on-the-air tv here switched to DVB-T a year ago so playing directly my TS recordings would have been nice, but I can live with XviD and H264, 99% of my video files use one or the other.

Limited HW acceleration is to be expected. It is just an affordable and fun project, not something that was intended to be a HTPC from the design stage.
MPEG-2 can be done in software, at least for standard-def (ie DVD folders and remuxes). Software decode of 1080i broadcasts....probably not.
HD audio is irrelevant, nobody will be buying this as a main HTPC for a high-end setup. I see people going wah wah I love HD audio in many posts, and then you see their setup, some basic $200 all-in-one sound system with plastic speakers
Nobody can tell the difference between DTS core 1500kbps and DTS-HD on such setups, blind tests confirm this.
