Klaus,
I have to be missing something basic here.
But then again maybe not.
I took the example that comes with the KRPano viewer download, "videointerface", and wrapped the <image> with <scene> opening and closing tags and the 360 video flattens out.
Just adding the <scene> tags causes this behavior.
Here is the relevant code from the modified example.
<!-- define the pano image and get the pano video from the videoplayer plugin (flash only) -->
<scene name="scene_video" title="Video" onstart="">
<image hfov="360" vfov="180" devices="flash">
<sphere url="plugin:video" />
</image>
<!-- the startup view settings -->
<view hlookat="+51" vlookat="0" fov="130" fovtype="HFOV" />
</scene>
All I did was add the <scene> tags. Nothing else.
Once I remove the <scene> tags the 360 video plays as expected.
What am I missing here?
