Jep it's java. I was fighting with it on another
testbed because it needed ant, javac and junit to compile/build.
Finally was able to build it and then found out I
could use the "binary" version (which is just a pre-made jar). The bug in
0.5 didn't really matter to me (if you start 10 streams the total execution will
stop as soon as one of the streams completes (Peter already mentioned
that).
But since I wanted to test a single stream in the
first place (where flazr will stop more or less simultaneous if you fire up 10
threads at the same time) I could have saved me the trouble (ant didn't want to
build itself for example ; had to fiddle in the build.xml since it didn't want
to pass on junit jars etc).
It's an odd tool, with a "groovy" interface. A
script language to start a java-tool. Never thought I'd end up there regarding
development ;)
Downside is the insane memory usage. Just started
100 threads and flazr quickly ate up around 1 gbyte of memory on my testclient
and the test crashed halfway reporting disconnects from Red5 due to the dreaded
insufficientBW error. And because of the 0.5 Flazr bug all threads came to a
grinding halt. Nevertheless I'm happy have a simple 'commandline tool' to do
some console testing.
I'll use some traffic-shaper on my client
(cbq + tc + iproute2) to see if I can avoid that insufficientBW
problem for longer tests.
Is
flazr written in C? I thought it was Java.

flazr.com works fine for me. It's as independent as
possible from any libaries, compilers and it's 100%
commandline.
Thanks again to Peter Thomas for pointing to
that package and supplying a nice example script.
rtmpdump?

Also,
the Red5 automated systemtest framework does something similar to this
(although it requires an X-server running in VNC-headless mode).
It uses the flashplayer itself (on Linux that means it must run on a
32-bit os) so that we don't have to debug some other RTMP tool, and can
take screen-shots of the headless flashplayer to help debug what's going
wrong.
It uses some code Xuggle previously released under
"theyard" open-source project and is licensed under LGPL. You can
find the relevant library and code here:
http://code.google.com/p/theyard/
That library
builds tests, but also wraps the NetConnection and NetStream objects in
fully tested state-machines to make it much easier to connect and
disconnect from servers.
We no longer actively work on this
project, but the code may be useful to some (altough I do maintain the
usage of it in the Red5 systemtest framework).

You

technically an option for me, right now.
Mate
I have a tool built for this very purpose however the wiki entry
for this is down and will be down for a while.

I have a need for this as well.
Up to now, I've just been using
multiple instances of
a generic FLV flash player (I've been using the
JWPlayer),
but this won't cut it for high volume load testing.
I
didn't think it would be too hard to write a dumb client using
the
red5 libraries, but I have not done it yet. I
will give it a go today
and let you know how it
worked out.
(Actually, as I write this, it looks like
Peter Thomas just sent an
example using another rtmp
library, so maybe my tinkering is
not
necessary)
That is correct ; you
can't do a decent test of a large production- enviroment
(multiple servers) with just one client behind a thin adsl/cable
connection. It's good enough to test the functionality but
stability, cpu-load or even stress-tests are out of the
question.
Currently trying to get Flazr to work. Will
keep you
posted.
