+# Video 3D support
+
+
+## Background
+
+3D Video is one of the buzzwords in home entertainment this year. TV and projectors get 3D ready. Blueray has 3D support  (via H264 MVC [1]). HDMI got 3D support (in 1.4a [2]). There are 3D still image cameras [3]. 
+
+
+## Task
+
+Videostreams in GStreamer need to be enhanced to support interleaving for stereoscopic video. Right now we have flags for interlaced video only [4]. 3D video can be packaged as interlaced or side by side. In the case of side by side, it can be left/right or top/bottom packing. Left/right is popular for images as it also allows parallel or cross-eyed viewing. Top/bottom is more efficient as one can process the video without strides. This is discussed in [[bug #611157|https://bugzilla.gnome.org/show_bug.cgi?id=611157]] 
+
+Once the video buffer metadata flags have been agreed on and added, we need conversion plugins: 
+
+* video3d-interleave: take two input streams of same caps and produce a 3D stream with correct buffer metadata according to variant selected via element property 
+* video3d-deinterleave: take a 3D videostream and split into two separate streams 
+* video3d-anaglyph: mix-down a 3D stream to a anaglyph rendering (red-green or red-cyan) 
+As a result of the GSoc project it would be nice to be able to capture from two same v4l2 cameras and show the result as anaglyph video on the screen. 
+
+Another idea would be to write a 2d to 3d converter plugin based on the avisynth script [5].
