The 1.0 viewer can already play back any mp4 with LR or TB and other filename extensions that support stereo playback, just like Oculus 360 videos.

You can also add a background image in the JSON (e.g. a cube map) with 'background' pointing to an image file. You can also set fovh/fovy for the video so that it is focused on part of the view. For example, we can render 60 deg stereo at 2048x 1024 and splat that over a still cube map render giving you 60 hz video inside an 18K stereo cube map scene, even if the FOV is limited.

Great I didn't know that thanks a lot, I guess a video with the same size as the stills?. any advise on compress for the MP4

So basically use just one side for the animation right? interesting will have a try on that.

thanks Goldrak :D

There are layers that you can feed to the compositor using 3 files:

myvideo_LR.mp4 // main layer

environment_cubemap.png //background layer image

myvideo_LR.json:
Code: Select all
{
   "title":      "Hello World",
   "author":      "otoy",
   "background":    "environment_cubemap.png",
   "loop":       true,   
   "fovh":      80,
   "fovv":      45
}

I'll try to get out a sample if there is time before Siggraph. I would just try playing back an mp4 over a setreo cube map image just to get a sense of how it works. Stick with stereo pano movies with limited FOV and you should be able to get animations playing over the cube maps - 2048 x 1024 side by side 60 hz wih 60 deg fov is a good overlay size.

The problem is the JSON files simply do not work. Even if you download the files from the phone, modify the text they're not picked up. My files whether cubemaps or videos will ALWAYS just use the content file name and show unspecified author :(

I found the initial problem, the cached meta.json files doesn;t seem to get updated if you modify the original json for the file. Not only that but if I add the background and FOV tags it just doesn't work. It then recreates a generic json file with unspecified author :(

So when can we expect an update of some sample content and JSON that actually works. Just telling us to do something doesn't cut it :(

I PM'd you. Sample content will be released with the 2.0 update - maybe in a week or two.
