Hi, it seems GSVideo does not like really low-res movies, or possibly movies with strange formats.

I am using GSVideo in the ADAvision processing sketch http://ladyada.net/make/adavision/software.html, which converts movies to LED information, so it would be nice to get the highest precision by having one pixel per LED.

I have tried my low res movies in the standard loop example that comes with GSVideo and have the same issues there, so I guess it is GSVideo related.

One example, I made a movie 150x10 pixels. This does not work. If I rescale this one to 50x30 pixels (same total amount of pixels) it works. Ideally I woul like to be able to work with movies with only 1 pixel height as well.

I also tried 8x8 and 64x1, neither worked.

All my tests work fine in quicktime player.

Any ideas on how I could get this to work?

Also, is there a minimum length for movies? I seem to have problem with really short clips (1-4 frames only).

I am using version 1.0.0.0 for macosx.

Thanks for any input.
