[FFmpeg-user] MPEG TS output - muxing queue - max_interleave_delta

[Matej]

Hi,

I tried to add -vsync 0 so the full command line was:
/root/ffmpeg/ffmpeg -loglevel debug -max_interleave_delta 15000000
-rtbufsize 128000k -threads 0 -re -i
"udp://@:1300?fifo_size=1000000&overrun_nonfatal=1" -re -i "
http://live.radiohit.si:9560" -codec copy -s 720x576 -q 10 -vsync 0
-shortest -f mpegts udp://192.168.1.150:1236?pkt_size=1316?buffer_size=65535

and the sound started to scratch and eventually stop:

I have also tried to stream this live audio stream as a mpegts with another
parallel ffmpeg process and then add this audio the same way as we add
video (-re -i udp://@:1301), but the same erors (Delay between .... muxing
queue) appear after almost the same time.

Any ideas will be very appreciated.
