Hi Albert, dear okular maintainers, I recently decided to hire KDAB again to implement a few missing multimedia features in Okular. In particular, I wanted https://bugs.kde.org/show_bug.cgi?id=301607 done, which concerns showing the poster images of movies inserted into a pdf using the LaTeX movie15 package[1]. This makes use of the JavaScript API, which hasn't been implemented yet. Tobias had a look at it to estimate the price, and found that the necessary API is fairly big, and that the JS code makes quite a few assumptions about the viewer code, which only hold for the Adobe reader. In his words, fixing 301607 would require large structural changes within okular, which are not worth the effort (and, of course, too expensive for my budget).
I am writing this to you mainly for your information. Unless those large structural changes are what you guys had planned anyway (unlikely), bug 301607 will not get implemented. Also, according to Tobias, the same problem will reappear in many cases where JS support is needed. This means trouble, as there are probably more important things relying on JS than my movie posters. There is another reason why it may not be worth a lot of effort to implement full movie15 support. Movie15 claims that it is deprecated, and recommends that a third alternative LaTeX multimedia package called 'media9' used instead: http://mirrors.ctan.org/macros/latex/contrib/media9/doc/media9.pdf This is a very powerful package, but it requires flash support to run (basically, to show a movie, it embeds a small video player application written in flash into the pdf file, and expects the viewer to run the flash app). I have always thought the idea a bit too outlandish to connect okular to a flash player, but maybe I am too timid? Tobias thinks that this may be feasible to do, if the API is well done. What do you guys think? Please cc me and Tobias if there should be a reply, we are both not on the list. Cheers, Oliver [1] The advantage of movie15 over the similar 'multimedia' package is that movie15 allows to embed the movie file into the pdf file (and not just link to it). That way everything is in a single file, which is helpful when you need to change computers really quick because you have found out on stage that your graphics driver does not like the projector after all.
