Flux and Feng realtime transcode and resize tests

We started to work on real time effects applied to live streams, while both flux 1.2 and feng 2.1 are still experimental and have some problems some results are already visible. The following screenshot has been taken from feng streaming a 320×200 and a 640×480 version of the same movie generated on real time by flux from a 1920×1080 version of the original movie.

Next step is to permit to flux to change on the fly the input source while still correctly performing transcoding and rtp packetization as a continuous live stream.
