It all started out simple: there was a video annotation with associated controls. It uses the quicktime plugin and when (i guess) apple and adobe fell out of love that one was ditched. Goodbye easy media support; it worked well and was quite robust too. In the years following that mechanisms came and went and we got this redicoulous complex (split annotation) media subystem that, guess what, depended on flash to show something at all. One had to embed some flash wrapper. Then adobe fell out of love with flash. (There was actually a time when SMIL was supported which was quite ok, but all my old demos (mediashow.pdf etc) now pop up with missing players. At least it was some kind of (probably as usual some reversed engineered application xml but I 'm not sure about that). Now, although I never really needed it. I spent a lot of time on all that and end of this year flash will be removed so I'll probably remove all that stuff from lmtx too. Goodbye audio and video ... I'd better spent my time on reading books, listening music or watching movies. I really don't understand those policies. Come up with a trivial annotation for video and audio, take a few stable formats and keep supporting that. How hard is that? Plenty of libraries for that too. I guess that the next thing to fade away is this 3d subsystem, and after that widgets and javascript (some already gone). So, probably best is some hyperlink to a simple local webpage that pops up the video. Don't rely on acrobat (and adobe) for long term support of anything beyond text. It never pays back to waste time on dynamic annotations, widgets etc. It probably never pays back to invest in anything those large companies come up with anyway. Don't buy into the 'there's a large company (or organization) behind it so it is okay and will stay'. (Actually, anything beyond text and graphics rendering in pdf is kind of weird. So, let's for instance not try to analyze tagged pdf here.) I'll probably add some code for url pop ups for media ... makes more sense. Delegate to a browser. But maybe it's better to first move the fancy annotation stuff to the attic.
