Pano2VR 4.5, 360-degree html5 video?

Post by MHornbostel » Wed Sep 04, 2013 7:49 pm

Pano2VR's Flash output has a way to do 360-degree video, making the entire panorama animated, but is there any procedure that can work with Pano2VR 4.5 that would allow us to do the same with the html5 output?

I have tried 'faking' it with a set of .mp4 hotspots but for me, it never lines up seamlessly along the edges.

Never mind, I came up with a solution I should've figured out earlier. It involves editing the XML file to accurately position six video faces, each with a 90-degree field of view.

You can't line up all the edges correctly in the Pano2vr editor, but typing in all the numbers by hand, can result in a seamless 360-degree video in HTML5.

Turns out something that looked like it was working well at first is glitchy in practice: Various visual problems in IE9 and Firefox, and doesn't run at all on Chrome.

I will need to try a few things and see if I can address the latency issues, some cube faces are off-sync with others probably because they loaded later; I could try reducing the download size further but it already has heavily compressed video as is. I also seem to be seeing a ton of intermittent black flickering which for me has been a frequently occurring problem with videos implemented using Pano2VR 4's media editor.

I have a list of ideas of things to try that might fix this, and haven't given up on it.

I'm still convinced that the basic idea can be made to work -the cube faces do line up nicely - but it will require some more iterations before it is really functional.

Update:

The bugs, it seems, aren't fixable. While the edges can all be made to line up fine, no matter what I do, the video on the various cube faces goes at least a little out of sync.

I really hope there is some way to make this work but right now I don't see it.

I will have to develop the HTML5 version of my multimedia art project Panoramic Worlds (http://www.panoramicworlds.com) with very limited use of video until there's a good way to do 360-degree video with Pano2VR's HTML5 output.

Seems you are nearly successful, except for synchronizing the 6 videos. Did you see this article that describes synchronizing 2 videos?
http://weblog.bocoup.com/html5-video-sy ... wo-videos/

Here is working code for the above article:

REFERENCES:
1. The trick is that none of the videos will play frame 23 until all of the videos have downloaded frame 23. In other words, continuously synchronize all the videos, as the video is playing.
2. See post by franzlorenzon here:
http://stackoverflow.com/questions/2654 ... ut-plugins
3. From both url's above, Mozilla's popcorn.js seems the current leader in synchronizing videos (and Microsoft too) on a web page:
http://popcornjs.org/
4. Playing 6 videos at once is...different. Different might be okay. Too soon to tell. I like your spirit. Usually the 6 videos are converted into image sequences and stitched. Thereby avoiding the need to synchronize the playback of 6 videos. Pano2vr currently provides a flash-only (i.e. non-html5) solution:

5. Perhaps, at this time, pano2vr is simply not the right tool for your job? It is okay to have more than one tool in your toolbox:
