We will for sure show some filter graphs in action.

Also there is a poster with basic ffmpeg command lines, to help us
explaining FFmpeg usage to visitors and for showing some of the
use cases for FFmpeg.

In the last years I had a filter graph that split the video and generated
a histogram of the pixel values and the wave form of the audio. At the end
everything was output along with the original video (without audio).

Another thing we traditionally do in Chemnitz is to encode video from a
web cam and immediately decode with motion vector visualization.

Both of this demos worked great to attract visitors and especially the
former to steer up interest for libavfilter.

Thomas posted both command lines on fb after last years event.

We will have 2 Displays facing to the visitors.

If you have ideas for filters or features you think we can show case
feel free to tell us. So we can try and see if it's feasible.
