o.k.
Here it is:


Call:
c:\ffmpeg\ffmpeg-istuff -re -i 
rtmp://rtmp.cdn.fem-net.de/rtmp/istuff_live -vcodec mpeg2video -s 
720x576 -r 25 -flags cgop+ilme -sc_threshold 1000000000 -b:v 5M 
-minrate:v 5M -maxrate:v 5M -bufsize:v 3.5M -acodec mp2 -ac 2 -b:a 192k 
-f rtp_mpegts -metadata service_provider="Some provider" -metadata 
service_name="Some Channel" rtp://192.168.1.244:5000?pkt_size=1316

(now i have set metadata after "rtp-mpegts")

c:\ffmpeg>ffmpeg -re -i rtmp://rtmp.cdn.fem-net.de/rtmp/istuff_live 
-vcodec mpeg2video -s 720x576 -r 25 -flags cgop+ilme -sc_threshold
