This must be an incredibly dumb question, but why would anyone ever use
mediaproxy over rtpproxy?
If one is written in Python and one in C, it seems to me that the
performance and scalability makes the choice of rtpproxy a no-brainer.
What benefit is there to using mediaproxy? More features and
capabilities, ease of configuration perhaps?

alex,
mediaproxy 2.0 is using linux kernel (not python code) to relay media
packets and the claim is close to wire speed performance.

mediaproxy is easy to use and set up. i don't have experience with
rtpproxy.
unfortunately i just discovered that there may be a serious problem with
mediaproxy 2.0 that was not there in mediaproxy 1.9. looks like
mediaproxy 2.0 does not allow nated ua1 behind one mediaproxy to talk to
nated ua2 behind another mediaproxy. dead lock happens and both
mediaproxies are waiting packets from each other and don't forward
packets that they have received from their uas.
so far i have not got any response to this from the developers.

Ah, I see. I was following some outdated information on this issue from
Flavio's book.
How does it use the kernel? Some sort of kernel-side module that has
plumbing into the IP routing/forwarding subsystem? Or some sort of ALG
module with hooks?

I imagine rather favourably, especially since many of them are embedded
systems built on Linux.

it uses linux conntrack modules. don't ask me about details.

if they don't have any custom hw support to do the forwarding, then i
don't see how they could perform much better on pc hardware.
