OK, as I suspected. Thanks for confirming.
The auth part is also only valid for a certain period of time.
rtmpsvr requires you to directs the traffic to it.
Aha! I hadn't clocked that. Thank you.
On Debian (Linux)
I have a user rtmp, under which I run rtmpsrv. The traffic to port 1935 is
redirected using iptables -
iptables -t nat -A OUTPUT -p tcp --dport 1935 -m owner \! --uid-owner rtmp \
-j REDIRECT
For mac don't have one to try this on..
sudo ipfw add 40 fwd 127.0.0.1,1935 tcp from any to any 1935
sudo ipfw add 40 fwd 127.0.0.1,1935 tcp from any to any 1935 not uid RTMP
See http://stream-recorder.com/forum/use-rtmpdump-rtmpsrv-mac-os-x-t7662.html
Made my system hang, as others in that forum thread reported. The
/etc/hosts trick mentioned there didn't work for me either. Meh.
Am still wondering if Wireshark is the way to go, but my experience
with Wireshark isn't very substantial, so it might be more effort than
it's worth.
Wireshark would be difficult to use for this.
I used rtmpsrv, and burpsuite, when I looked at fixing get_flash_videos
channel 5 downloads. You set the browser to use burpsuite as it's proxy
server.
From comparing the rtmpsrv, and get_iplayer debug, should be able to
determine the correct parameters for rtmpdump.
Things like undefine, duplication ... the changeable part below is the
&auth=....&, replace that from what get_iplayer --debug gives

If you compare,
get_iplayer is not passing the correct parameters to rtmpdump, which why you
get the access error.
Aha! Thank you for pointing this out. Is this a bug in get_iplayer? If
so, ought it to be reported somewhere, or is this mailing list thread
sufficient?
Also, please could someone comment on this?
t's not a bug strictly as it's not Iplayer content. The fact the
parameters are close to being correct means get_iplayer could be made to
work.
Thanks again,
Sam
