Re: Transport stream source

[David Oriot]

Hello Ralf,

If you need a TS streaming source, the "simplest" method is to use your national broadcaster 's one (if you can cope with the bitrate). 

You can use simply use a DVB-T USB dongle (the so-called rtl-USB dongle) connected to your TV aerial and then rum the very good DVBlast software from the VLC team to stream what have been demodulated by the dongle.

Simply "tune" to your favourite DTV channel and DVBlast will stream the TS over UDP.

Happy Easter.

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
