`juice: Send failed, buffer is full` error in media-sender example

The warning means either you are sending faster than the network link can handle or the system maximum UDP socket buffer size is too small to contain a single frame. Since you are sending at a rather low bitrate here, it's probably the latter.

On Linux, you can increase the maximum socket buffer size with:

$ sudo sysctl -w net.core.wmem_max=1048576
$ sudo sysctl -w net.core.rmem_max=1048576

The change can be made persistent in /etc/sysctl.conf.

Running that didn't help. I don't think the issue is at that level, because as I said before, I can use GStreamer's udpsrc to view the screen without any problems.

Did you run it on the sender host before starting the media-sender?

The warning specifically means that a packet is dropped because the socket buffer is full. It can be explained only by a too small socket buffer or sending over link capacity. The stream might still be fine as the decoder is tolerant to losses.

Yes. Should I try running it on the receiving side as well?

No, setting it on sender should be sufficient. What is your network setup?

By the way, udpsink in your pipeline has host=0.0.0.0, whereas it should be host=127.0.0.1. 0.0.0.0 would literally mean "broadcast to any address" and you don't want to do that (it should still send to localhost in that case but you never know).
