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

While this is probably unrelated, these unused options make
the issue needlessly harder to debug...

Can you try to record the network stream to allow us to reproduce?
Why is rtp input from the local system necessary?

Hello everybody

Sorry for my delay in reply in my response.
1)I have attached a link for a small section of the flow that I capture
https://drive.google.com/file/d/1c7IwXuu9GLMDo70A8gRyy1pUKntgxrM0/view?usp=sharing

2) I catpure multiple dvb-t or dvb-s signal with dvblast and his outgoing
are rtp, then I use the rpt to transcoding the signal with ffmpeg mp2g to
h264 and audio to aac. and republish it to my server.

Thanks a lot for your help.
Best regards
