I've been for a while trying to get some level of behaviour with HTML5 video with my HDHR5-4DT, but have had no luck because all browsers I've used says that "no Access-Control-Allow-Origin header is present on the requested resource".
I remember making a separate thread about having a Access-Control-Allow-Origin header added to the port 5004 streams in a future firmware update more than a year ago, as well as staff member nick making a post about telling the developers about this, but the thread seems to have vanished without a trace, and most web browsers won't talk to "different" domains/hosts via XHR or other means unless this header is present (i.e. * to allow all).
EDIT: Just to expand, this header is indeed present on port 80 which provides the web console, but not on the video streams themselves served up via port 5004.
Access-Control-Allow-Origin header to allow local html5 communication
Re: Access-Control-Allow-Origin header to allow local html5 communication
Added. It will be in the next beta firmware release (likely later this week).
