Hello Everybody


I have this ffmpeg command
ffmpeg -i rtp://127.0.0.1:6000 -map 0:4 -map 0:2 -vcodec libx264 -b:v 1500k
-s 720x576 -acodec aac  -ab 128k -ac 2 -ar 48000 -r 25 -f flv
rtmp://encoder....

I have a lot of errors when i start capture a mpeg2 signal, and after a
while the capture starts to fail

Thanks a lot for your help
Best regards
