3DTV Support - Play "3D" Movies in XBMC plus have GUI / OSD and subtitles just work?

How did you get your device to playback top/bottom. I have a single 3d file and it just displays the top and bottom in one video, the playback is not merged.... is this a container issue, it is an MKV

The good news is that it works with the newest Windows build, so no more DS player. More good news is playing a full SBS file with the GT430 knocks my TV into 3D mode. Its like the GPU knows to send the correct "its 3D" signal to my TV. So one day this could be easy - its not like that mode is locked in DRM hell.

More bad news was it did kinda lag. I am gonna try soon in Linux to see if the file actually plays at that res on that build.

Did you get this working on Linux? Also, did you use an external player?

I playback a top/bottom file on my XBMC and it just shows a video with two playback, top and bottom. It does not merge the images.

I have XBMC 10.0, GT430, latest graphics drivers, a Sony 3D TV, and Ubuntu 10.10. ANy suggestions on what I am doing wrong?

I may have found the problem... I will need to check when I get home

Supposedly this information is also found in something called a manooal, or manual - not sure how you say it

Sorry, I don't have time to read the whole thread, so I might be repeating stuff someone already posted. Also I am a simple user without any dev experience, so the post might look a bit dactylic. My setup (I believe that would be typical XBMC 3D):
Geforce GT430
New Nvidia 260.xx drivers (with <a href="http://www.nvidia.com/object/3dtv-play.html">3DTV Play</a> support)
HDMI 1.4 cable
Viera VT20 (plasma with shutter glasses)
In this setup Geforce supports 3DTV natively. E.g. it can detect, that stereo content is played, and inform 3DTV to change mode accordingly, sync with glasses etc. IMHO 3D support is all about letting the Nvidia driver "know", that XBMC is playing stereo file (which can be side by side, over-under or BD3D). I can already play stereo pairs in XBMC, but TV mode needs to be adjusted manually every time, and UI is painful to look at. BD3D is not supported, so I am using the external player (Arcsoft TMT+daemon tools).
So to support 3D we need to:
- Detect stereopairs and pass corresponding info to Nvidia 3D Vision.
- Play BD3D as iso or mounted iso, as far as I know even regular BD are not supported yet.
I believe to develop/test the whole thing you need only 3D Vision set (less than 200 bucks), and 120 Hz monitor (a bit more than 200 bucks, but not much more).

how about those of us with polarized dual projector setups? It's really great, all you really need is two projectors, a metallized screen, polarizers and a pair of passive glasses that cost a buck each. (i got 15 pairs for $20 shipped.)

One significant advantage is that you can output true 23,976Hz, because
with a 120Hz shutter-glasses TV you'll get pulldown issues playing a 24fps 3d film.

AND, right now a setup like this is cheaper than just about any 3d-ready tv on the market.. and don't even get me started on price per inch >.<


Anyway, it's simply a matter of decoding the stream(or streams) and outputting the images for left and right to two separate X monitors simultaneously. (with of course the double subtitles that you'll need for any 3dtv too) Planar 3d displays use the same dual output btw.

No image sync or glasses control, just the two separate outputs.


Stereoscopic Player works fine, but it's not for linux and doesn't have a very sexy interface.. it's kinda like mplayerc but more grayish and boring, if it's at all possible.



btw, i think xbmc should scan the filenames for "3D" and more specifically "Half SBS" and so on, just to automagically know how it should output the file.. end users don't want to work through context menus and mark all their 3d stuff as sbs or over/under and so on

Not really. Panasonic supports "true" 24p, as well of bunch of others shutter-glass TVs.

I got mine to work with Side-by-side and Top/Bottom, however the TV did not automatically change into the appropriate mode - as if the card was not telling the TV that 3D content was being displayed.

Can anyone think of a reason why this might be the case?

oh, my bad. I thought all the 3d-ready shutter-glass tvs displayed 3d in 120Hz page-flip format.

edit; did some searching and apparently you have to choose between 60Hz and 48Hz per eye.. so it's either pulldown judder or plain old flicker, then.

RealD cinemas kind of use a shutter, too, but it's located inside the projector, and runs at 144Hz. so that's 3:3 pulldown at 72Hz per eye.
no flicker and noo judder. What were the 3dtv makers thinking?

My Panasonic Viera GT25 has no problems with pulldown issues, and you can see that in several reviews of the VT25 (which is pretty much the same tv minus a few inputs on the back panel) that Panasonic has taken care of that problem quite well...

Panasonic also set up their 3d systems to handle many different variations of 3d, from SBS, over under, stereoscopic, anaglyph, etc...all selectable by remote or you can simply leave it on autodetect...the tv also does a good job of upconverting 2d to 3d, as my girlfriend found out last night the hard way when she accidentally hit the 2d-3d menu button during an episode of "16 and pregnant"...don't think she'll be messing with that feature again anytime soon, lol.

that's strange as last time I looked my VT25 didn't have a 2D to 3D mode - I haven't looked since the last update though.
