Hi,
I want to write an app that captures video from a webcam. On my main form, there will be 2 video players. The first will be the original video stream. The second will be a downscaled version. In essence, I want the second player to show a pixelated version of the first. How can this be done? what functions should I use? Please guide me in the right direction. I will run this in linux.

Please do your own research. This is not a LibVLC problem per se.

I am not reporting a bug in LibVLC, Im simply looking for some possibilities in how Id go about pixelating a video real time. I have no problem coding in C or Pascal. Just looking for some ideas as Im somewhat new to Video processing.
