That fixed it. I had to increase net.core.rmem_max to 100000000 (100M)
before the video became perfectly smooth. Even with 10MB there were some
skips. It was not neccessary to change net.core.wmem_max (my system defaults
were 212992). Also, it was only necessary to set buffer-size on the
receiver, not on the sender.

Thanks a lot for the solution.

I will file a bug, thanks.
