[Gajim-devel] 0.16.5 file transfers and audio/video - do they work for anyone at all?

Here's the log showing the scenario where two Gajim instances on the same LAN sub-net cannot exchange one single small file.
No firewall here, the sender sees the xfer completed, but recipient gets an error and the transfer never completes for them.

Hi Alex,

Indeed we have exchanged a few mails about your file transfer problems.
And to sum up: You send me 3 XML logs, and each logs was a different case. First one an d SI / IBB transfer, second one a SI / socks5 transfer, and third one, a Jingle / socks5 transfer.

With your first logs, I was able to fix the problem. IBB transfer now should work correctly.

For your second logs, I told you why it fails:
  - Your contact don't support jingle file transfer (a more recent method)
  - Your contact can't connect Gajim on both your IPs : X.Y.Z.T and .U on port 28011 (maybe a firewall on one of the machines)
  - Your server don't offer a file transfer proxy """

And for the third logs, you tried to transfer sever files at the same time. I asked you a question about your network configuration and to try with only one file, and I am waiting your reply.

For Audio / Video calls, yes it seems libs have changed things. It doesn't work very well in 0.16 branch. I try to have it working correctly in the next major release.
