Hi,
I am the author of an SL media system that relies on HTML5 video using Shared Media and MOAP to provide synchronized streams from various video sites such as YouTube, Vimeo and others. Going through many iterations, this product has taken many years to develop (on and off), and back in August I was getting close to finally coming out of beta and fully releasing.
I first noticed the problem after upgrading to Firestorm 5.1.7, but subsequently found that the official viewer broken in the same way at version 5.1.3. Just about all videos stopped working except for some YouTube videos. This affects all platforms, and there are numerous other people reporting their TV systems are broken too.
I reported the bug to Firestorm at first (https://jira.phoenixviewer.com/browse/FIRE-22862), and then to Linden (https://jira.secondlife.com/browse/BUG-225207), and have been patiently watching the JIRAs waiting for some kind of progress on this, but nothing happened until a couple of days ago when a Linden CLOSED another identical related bug (https://jira.secondlife.com/browse/BUG-225196) as "Expected Behavior", pointed to a Wiki update they had just made that says ..
""Note: At this time, it is not possible to play embedded .mp4 files in Second Life using Shared Media. "
... and directs the submitter to create a Feature Request for something that is most definitely not a new feature, it has been working for years and there are products in the marketplace that rely on it!
The irony is, in a world that is trying to get rid of Flash and replace it with HTML5, we now have a viewer that ONLY supports Flash video despite having previously supported HTML5 very well.
Is there anyone out there who can shed some light on what is going on here? I am getting frustrated questions from my customers, I am frustrated, and am just about at the point of shutting down my product and giving up with SL entirely
