Gstreamer gst-launch udpsrc in ubuntu 16.04 doesn't work

Question

I'm trying to save multicast h264 ts to file using this command in gstreamer in ubuntu 16.04:

"gst-launch-1.0 udpsrc multicast-iface=eno1 uri=udp://224.1.1.1:3001 ! queue ! filesink location=test.mp4"

This command works in gstreamer on windows but when I try the same command in linux it doesn't work- test.mp4 file is created but nothing is written in it.

I also tried to play uri=udp://224.1.1.1:3001 in vlc and it can't play it either in ubuntu. In windows it works.

Any help will be appreciated!

Thanks

Answer 1

If you have mentioned anaconda path in bashrc, comment it, and relaunch the terminal. Worked for me.

Seems like firewall is blocking. You need to enable the port, probably if you look using wireshark you might see the packets.

To disable firewall refer to [1] , doing this will enable the port and you should be able to get the udp packets.
