[Beta - Update 2013/08/09] MP3D - Render 3D videos via MediaPortal! (1 Viewer)

[morpheus_xx]

I have a 3D capable display now and also thought about future 3D support for MP2.

Some time ago I made experiments to render the whole screen as SBS only using one single frame and stretching it to 2 halves. If you would do a proper 3D gui we could render each frame twice, using a slightly different camera position (see also http://www.nvidia.com/content/GTC-2010/pdfs/2010_GTC2010.pdf for background).

That would also require to have proper Z-information on all screen elements available. The video frame itself then should be handled differently (i.e. if it comes already as SBS you must not split and copy it again). This could be managed if the VideoBrush gets an information which render pass is done currently (left or right side) so it can decide how to process the frame accordingly.

Currently I have no concrete plans to work in this section, just sharing some basic ideas here

@tourettes
I was talking from a plugin's point of view. You are talking from MP core's point of view.
Are you suggesting abandoning 3d support via a plugin and making it built-in (MP1, MP2)? (I'm very interested in this approach.)

Better support could be gained by native implementation (also some of the 3rd party components are required to be able to support 3D Blu-rays). I have no short term (or even long term) plans currently to for looking at the 3D support - few days ago I bought a new 2D video projector. It will last for many years

This could be managed if the VideoBrush gets an information which render pass is done currently (left or right side) so it can decide how to process the frame accordingly.

That would be only a partial solution as it wont suport all the video sources. It would be good for the scene rips but it would be non-usable for example for the Blu-ray content.

You're in my mind!

Of course the VideoBrush would need to know which kind of input arrives, so it can decide if it should take different scanlines, half frames, or only each 2nd frame for each (left/right) pass.

And that path leads all the way down to libbluray in the whole chain as all components need to have the support.

For the brush itself it would be better if the video renderer (EVR or DirectX11.1) would be having the final word on every pixel how it gets renderred to the screen. It is better to have all the logic in one place to allow mixing up gamma, color space conversions etc. This of course applies only when the video is renderred in a full screen - probably it would be doable if the brush would have special full screen mode where the processing is disabled.

 

[ScRePt]

My view is that the Brushes can solve the problem. Applying gammas/color spaces etc can be done on the whole video and then the brush would do the splitting. This way is also "themable" and does not require special filters/renderers. Could be slower though ... my 2c

Anyway, back to MP1, I am open to any suggestions to overcome the 3dtv.at filter requirement.

Is it possible to add Nvidia 3D Vision as the Output format? I installed stereoscopic player 1.8 and it is available as an option within the program.
I have a 3d ready DLP projector and my two choices for viewing 3d are Nvidia Vision, or Software Pageflipping with DLP glasses control.

Also, I have this installed with MP 1.2.3 and at the end of any video I watch with 3D mode enabled, Mediaportal Freezes.

No, unfortunately NVIDIA renderer is not supported.

 

[ronsonol]

Thanks for the reply,
is that because const int METHOD_NVIDIA = 5; // Requires Stereo Renderer?
Is is not possible to add this to the post-processing list just as you do with the transformation filter?
