Thanks very much, Thanks to you I have understood some more things and it is working now much better. The CPU load is suspiciously low (65%), I would expect it to be higher. I will do some more tests regarding that. My project is quiet big and I am now during my first steps so ... much more questions are due to come. and the next one is ... how do I stream it so that it will be opened by VLC or windows media player. If I use: ... ffenc_flv ! udpsink port=5000 and then open the VLC for streaming at :  udp://localhost:5000 I would expect it to be shown yet I don't. Any suggestions?
