well nothing works so far with jmcvideo…
I emailed angus forbes now. I can only suspect that it is because I am on Maverick64 , and javafx 1.2, which is jmcvideo build upon, is only available in 32bits. Now I have inspected the native gstreamer library (libGStreamer.so in linux) and I have all the libraries installed in 32bit, which it links to, so I thought that part should work fine… maybe I am wrong here, and it needs sth. else.

meanwhile, do you remember why You guys did not succeed in letting sv run on linux? I only ask because you explicitely say so on the page…

and if jmcvideo is only needed for loading videos (and thats hopefully not really a big part of sv), would it be possible for a processing – newbie to hook up annother library for doing the video loading? http://gsvideo.sourceforge.net/ also uses gstreamer, as jmcvideo does through javafx….

so you think its all about codecs and I do not have to alter code? I hope you are right, I will try some movs, oggs etc. with the jmc demo applications for playing videos and then try again in sv

Hi cellstorm,

I’m afraid that non-OSX development is a bit tricky. Certain codecs would work okay, and others wouldn’t.

I would experiment with JMC Movie and various Linux codecs to see what works, and then use ffmpeg or mencoder to convert all the videos to that format.

Sorry I can’t be more help, it’s been a couple of years since I worked on this!

Hi Cellstorm, first of all check that your movies are in a folder called ‘data’. The version on Github already has a demo movie in that folder and should work… please let me know if this still doesn’t work and I will try help you
