rtmpe and swf verification problems with tv4play.se

any ANONYMOUS forum user · #1 12-16-2009, 02:37 AM

Hi, I'm trying to download video from tv4play.se, i.e. this video

Code:

http://www.tv4play.se/noje_och_humor/forkvall?videoId=1.1357384

I'm not getting it to work. Tried both on Windows and Linux. Any ideas why?

command:

Code:

rtmpdump --debug --swfUrl 'http://cdn01.tv4.se/polopoly_fs/1.939636.1259243966!approot/tv4video.swf' --swfhash '422ba2018ca814bc67ec59b39c0ba1b4f5d3246dbd137b4fd63ba327487848d5' --swfsize '124349' --rtmp 'rtmpe://cp70051.edgefcs.net/tv4ondemand' --app 'tv4ondemand' --playpath 'mp4:/mp4root/2009-11-25/A53G0CFN-FORKVALLHALSA_885464_T6MP48_.mp4' -o out.flv

Looks like your swfUrl / swfSize / swfHash are invalid. I found these parameters from that site and it works for me:

rtmpdump --debug --swfUrl 'http://www.tv4play.se/polopoly_fs/1.939636.1260780980!approot/superspelarflashlet.swf' --swfhash 'e1797c5d77de16df98184bbfa4399bb03009dbd6cace43037 77b34eeab45b7e2' --swfsize '225218' --rtmp 'rtmp://cp70051.edgefcs.net/tv4ondemand?ovpfv=2.1.2' --playpath 'mp4:/mp4root/2009-11-25/A53G0CFN-FORKVALLHALSA_885464_T6MP48_.mp4' -o out.flv -p "http://www.tv4play.se/noje_och_humor/forkvall?videoId=1.1357384"

Notice that it doesn't need rtmpe.

how can you find the correct swf url?

I used this:

This started as a copy of streams.c and then I ripped out all the HTTP code
and added in all the RTMP server side handling. I had originally planned to
write a complete transparent proxy, but I'm not sure that's really necessary
at this point.

All you need to do is redirect your Flash clients to the machine running this
server and it will dump out all the connect / play parameters that the Flash
client sent. The simplest way to cause the redirect is by editing /etc/hosts
when you know the hostname of the RTMP server, and point it to localhost while
running rtmpsrv on your machine.

The other way on Linux is to use iptables to redirect all outbound RTMP
connections. You can do this as root:

iptables -t nat -A OUTPUT -p tcp --dport 1935 -j REDIRECT

In my original plan I would have the transparent proxy running as a special
user (e.g. user "proxy"), and regular flash clients running as any other user.
In that case the proxy would make the connection to the real RTMP server. The
iptables rule would look like this:

iptables -t nat -A OUTPUT -p tcp --dport 1935 -m owner \! --uid-owner proxy -j
REDIRECT

That should give you some idea of where to go from here.

The output from your web page was this:
