i'm trying to ingest 3 multicast streams using the same port.
i can change the the multicast addresses (239.255.x.x) but not the ports
i can also change the group #s
i read on the FFmpeg Protocols Documentation page under udp that:
sources=address[,address]Only receive packets sent from the specified
addresses. In case of multicast, also subscribe to multicast traffic coming
from these addresses only.
Ignore packets sent from the specified addresses. In case of multicast,
also exclude the source addresses in the multicast subscription.
however, the following doesn't seem to work & i'm not able to find others
with the same kind of port problem
ffmpeg -i udp://192.168.1.2:5004*?sources=18.104.22.168* -vcodec copy
-codec:a aac -b:a 128k -f flv out.flv
am i missing something in the syntax or address assignment?
thx for all the bits :)
Have you tried debugging your command?
Usually you need to send a complete uncut console output from ffmpeg along with your issue
ffmpeg -loglevel debug -i udp://@22.214.171.124:5004 -f raw -
