Bit curios about the possibility to embed a custom HTML5 video player into Tumblr. How it works now is basically that you put in an URL or embed code to Youtube or any other service and it'll load up the video and show it in the dashboard feed and on your blog.
I just checked with Vimeo, and in that case it seems like it fetches a vimeo iframe with the video (I guess it's their embed code) and inject it into the DOM when the play button is pressed.
Would it be possible to mimic this behaviour with a custom iframe of my own? Make Tumblr accept my own embed code (iframe based) that leads to a HTMl5 video and also serve up a preview image before the video is actually played.
So when I'd input for example, www.mydomain.com/video1
it would recognize it as a video and have it behave like any other video service out there.
Or would it otherwise be possible to do via their API?
Just to clarify: I would not want to use the Tumblr HTML5 video player, but a player of my own chosing.
