Hello Thales,
I've just gotten finished fighting a similar problem. I suspect that the video stream you are trying to display has a format that DirectFB does not have compiled/linked into the rendering engine. While you probably have the correct CODEC installed to see it under a standard player, DirectFB has no way of understanding it. Try converting it to MPEG.

The directfb´s examples works very well. What´s the matter???
