There are many different ways to output 3D streams. Attached is a list from the windows "Stereoscopic Player" program (which is also bundled with nvidia glasses/zalman monitors and others) that shows what output formats it supports. This and the DepthQ player seem to be the most featureful and up to date programs that play back 3D videos. If you can't see the image, here is a shorter list of its output formats: Source (Plays back unaltered, for spanned dual projector or new model 3DTV) Monoscopic (Shows left or right eye of stereo stream only) Dual Screen Output NVIDIA Stereo Driver (3D Vision) StereoBright™ Quad Buffered OpenGL (hardware page-flipping) Sharp 3D Display 3D Enabled DLP-TV (uses checkerboard format) iZ3D Monitor Tridelity SL Series 3D Displays SIS Attachment 4 Side By Side Over/Under Row Interlaced Column Interlaced True Anaglyph Red - Blue True Anaglyph Red - Green Gray Anaglyph Red - Cyan Gray Anaglyph Yellow - Blue Gray Anaglyph Green - Magenta Half Color Anaglyph Red - Cyan Half Color Anaglyph Yellow - Blue Half Color Anaglyph Green - Magenta Color Anaglyph Red - Cyan Color Anaglyph Yellow - Blue Color Anaglyph Green - Magenta Optimized Anaglyph Red - Cyan Optimized Anaglyph Yellow - Blue Optimized Anaglyph Green - Magenta Dual projector setup (with polarized filters) or late-model LED 3DTV's (Samsung, Panasonic) do not require any special output method from gstreamer to view 3D, but: In order to have mainstream adoption of 3D playback with gstreamer, in my opinion, these are the most widely used output methods that need to be supported: Unaltered (like with the new LED 3DTV's, could also support automatic switching to 3D mode if using HDMI 1.4) Quad-Buffered OpenGL (supported on professional cards like Nvidia Quadro) Nvidia 3D Vision Horizontal Interlacing (Zalman monitor) 3D DLP TV (checkerboard) Anaglyph Also to support Autostereoscopic displays (lenticular or parallax barrier), a multi-view output method would be required. For example with lenticular displays, typically you output 8 or 9 different camera angles, and for parallax, a lot of times you use a custom 3x3 grid made from a stereo stream to enable the multiple viewing angles. If you have any questions I would be glad to help. -bp 2010/05/23 19:00 "Martin Bisson" <<a href="mailto:martin.bisson@gmail.com">martin.bisson@gmail.com</a>>: <div class="im"> bparker wrote: > > What output formats are you planning to support?

Dave mentioned memory consecutive, which would be the same thing as top-bottom for non-planar formats. I guess I could add it for planar formats, if needed... I also plan to add support for red/cyan and red/green image types.
