Cool, I was sure it would be interesting for some.
What it does is simply replace the <img/> elements in the Grid of
OpenLayers with <video/> elements. So, it works only with HTML5 support. We
have a use case here with density data and I have implemented it as an
extension to OpenLayers as mentioned. Unfortunately, it's still in
alpha/beta, so it's not public yet. And also (surprisingly) it does not
work correctly in Google Chrome but in Firefox.
You can pull from the mentioned repo to test it out.
Basically on the WMS side I simply cached the n layers (one for each frame)
and then wrote a shell script to append those images to a video with
ffmpeg. On the mapcache side I used a trick to fool it the correct mime
type. So, it only works with a full cache. We used MapServer and MapCache
We are thinking of presenting this with our use case at one of the upcoming
conferences. Interested? Please reply here.
