Hello.If the question is, how can one receive an multicast udp transport stream into udp gr source block?
as a test, i've an encoder that encodes a transport stream to udp://239.255.42.42:5004 -
socat udp4-recv:5004,ip-add-membership=239.255.42.42.0:0.0.0 udp4-sendto:192.168.12.12:5006
now send it back out using multicast address 239.255.99.99: 5008 from gr block -

Dear all,
instead of using a file source, I would like to get data from a video
stream into GNU Radio. Is this possible?
With VLC, I can connect to the stream using a URL like
udp://230.0.0.10:1234. How can I do this in GNU Radio? I have tried to
use a UDP source with this address and payload size 1316 (needed for VLC
when it connects to a UDP sink in GNU Radio) and to pass the data to a
UDP sink at address 230.0.0.20:10000 and payload size 1316 to which I
can connect with VLC to see if it works but when I start the flow graph,
nothing seems to come out, VLC tries in vain to connect.
Thank you very much and happy easter!
Kind regards,
Ralf
