h264. My bat-senses say that you might have more than one thing connected to
port 40000 on your system. I don't remember if I've already asked you to do
so, but could you get a tcpdump from the receiving side/machine (well,
actually it should be the same as the sending one ;) ). You can collect it
with:

tcpdump -ilo -s0 -w/path/to/tcpdump.cap
