Hey,

I'm going to stream a conference, i'm using pure HTML5 video-tag for now (with cortado fallback), but I'm looking into using mwembed or a similar player if it can provide more features and niceties.

One requirement of this particular conference is that captioning (subtitles) is present.

I'm thinking about using COMET for this, so ajax server-side push messages, and built a small website for the translator to sit and type in the text.

Has anyone else looked into this? Obviously, synchronization is a huge problem, and that has been fixed in the spec, but none of the browsers has implemented it, so everything will be horribly out of sync, but sync is no requirement (but very nice of course).

Also, as an aside, it'd be nice to have a chat, where people watching the stream can chat, and maybe get Twitter and Identica-messages into the chat box when they arrive. With the comet approach this should be quite doable.
