I am trying to use Tracker for automated tracking of rat behavior videos. My videos were compressed using lagarith lossless codec (source: http://lags.leetcode.net/codec.html). The video size is 1000 frames, with each frame size 960 x 792 encoded @ 30fps. I am trying to upload these videos on Tracker using either Xuggle or QuickTime, but the video loading fails after about 1% with the error message "Video could not be opened".
Can you open your lagarith videos in the QuickTime player? I think QuickTime is your best option for this codec--I doubt that Xuggle knows how to handle it.
Thanks for the reply. Initially Quick Time asked for additional plugins to support the file and I installed both DivX and XVid. It is able to load the video now, but is playing a blank/dark video.
Would you know of any additional plugins with Quick Time that allow lagarith compatibility? I searched and I think Mac doesn't yet support that codec.
Sorry, Urvashi, I wish I could help but I really don't know anything about the lagarith codec. If you do get it working on Mac, please be sure to let me (and the discussion group) know :-) Doug
