I’m attempting to do something in flash but don’t know if it is possible. I have a series of cameras that output a stitched horizontal video. I need to somehow convert this video feed to a spherical panorama, and have it happen LIVE. I was wondering if there was a way to do this within Away, somehow mapping the live video feed to the inside of a sphere with a camera at the center.

You should show a image of the panorama.

If you mean an eyefish stiched 360 video
Only thing required is a “videomaterial”, a sphere.scale *-1 or using Meshhelper.invertFaces and set boolean to keep uv’s to prevent image flip.

you can even test it with an old editor of mine here: (supports both 360 video and stills )www.closier.nl/downloads/sfeerz/Sfeerz.air

For video source I mean equirectangular projection videos, think video version of any of these still images on flickr

Maybe that works with Fabrice’s way.
If the Video is ok.

I tested with Flickr photo.
See attached my swf.
Cheers.

private function initMaterials():void
  {   
   var panoramaBd:BitmapData = Cast.bitmapData(PanoramaImg);
   var mat:Matrix = new Matrix();
   var texResolution:uint = 2048;
   var scaleH:Number = 1/(panoramaBd.height/texResolution);
   var scaleW:Number = (panoramaBd.height/panoramaBd.width)*scaleH;
   trace(panoramaBd.height*scaleH);
   trace(panoramaBd.width*scaleW);
   mat.scale(scaleW,scaleH);
   var pow2PanoramaBd:BitmapData = new BitmapData(texResolution,texResolution,false);
   pow2PanoramaBd.draw(panoramaBd,mat);
   panoramaMaterial = new TextureMaterial(Cast.bitmapTexture(pow2PanoramaBd));
  }
  
  private function initObjects():void
  {
   panoramaMesh = new Mesh(new SphereGeometry(400,32,32), panoramaMaterial);
   panoramaMesh.geometry.convertToSeparateBuffers();
   MeshHelper.invertFaces(panoramaMesh);
   view.scene.addChild(panoramaMesh);
   panoramaMesh.x = 0;
   panoramaMesh.y = 0;
   panoramaMesh.z = 0;
  }
