Hi J-S, Thanks for the link to the camera. I tried the mjpeg osgmovie commandline and it took a number of seconds before the first frame came up then looked to be working but then eventually stopped update. The media.sav commandline does nothing right now, osgmovie just hangs without reporting anything.
I haven't yet looked into the ffmpeg plugin and how it's coping with these sources, but I am using svn/trunk rather than your suggested changes that I haven't merged. Do your suggested changes effect the end result at all? Robert.
