[Cem İbrahim ARI]

Sorry about external link,

Command line i use :
ffmpeg -probesize 4M -analyzeduration 10000000 -rtbufsize 10000000 -f
mpegts -i "http://10.0.0.5:4242/chnum/1" -acodec aac -strict experimental
-ar 22050 -ac 2 -async 1 -b:a 48k -vcodec libx264 -x264opts
keyint=10:partitions=none,i8x8,i4x4:me=umh:merange=16:subme=3:ref=1:mixed-refs=no:trellis=0:mbtree=no:weightp=0:bitrate=1408
-sc_threshold 0 -deblock 1:2 -r 25 -bufsize 2M -s 720x576 -ar 44100 -b:v
128k -f flv "rtmp://127.0.0.1/live/teststream"

And console output is;
