for youtube videos want code:

mediaplayer.setplaysubitems(true); // <--- important youtube media 

and code below gets subitems.

mediaplayer.addmediaplayereventlistener(new mediaplayereventadapter() {       @override       public void mediasubitemadded(mediaplayer mediaplayer, libvlc_media_t subitem) {         list<string> items = mediaplayer.subitems();         system.out.println(items);         system.out.println(mediaplayer.subitemcount());       }     }); 

when working, noticed above code printing 2 subitems, 1 of them being actual url of video.

but prints 1 subitem this:

[http://www.youtube.com/get_video_info?video_id=1t8fl96hpqi&el=detailpage]

which not actual url of video , think thats why not playing.

any ideas of why happening? did google change in format of youtube pages?

i tried upgrading vlc youtube.lua file suggested in tutorial found no luck.

also, when use same link in vlc, works fine.

specs:

ubuntu 12.0.4 64 bits

vlc media player 2.0.5 twoflower

vlcj 2.2.0

thanks in advance,

marios

did google change in format of youtube pages?

most likely. happens time, point don't rely on functionality in application (even though it'd nice if could.) it's temperamental, 1 small change layout of youtube , stops working. i'm not sure lua file vlcj uses same install of vlc (though wrong there.)
