[FFmpeg-user] Multiple live input stops when one input is lost

Hi all,

I'd like to remux two live SPTS inputs (in this case two channels downlinked from different dishes) in a single MPTS with two programs in, and I'm doing it with this command:

ffmpeg -i udp:// -i udp:// -c copy -map 0:0 -map 0:1 -map 1:0 -map 1:1 -program title=Program_1:st=0:st=1 -program title=Program_2:st=2:st=3 -f mpegts udp://

Everything works as expected, but if I miss one input ffmpeg just hangs waiting for the input to come back.

Is there any way to force ffmpeg to go ahead streaming only the available input until the lost input is back again?

Kind regards,
Alex Molon
