4. Right click on the RTMP URL. Select "Download by Blader" item from the pop-up menu.
   
   
5. Blader will be started and a dialog will pop up for adding task. You can choose location for saving the RTMP resource and rename it.

7. If thr RTMP resource you are downloading requires authorization, Blader will pop up a dialog where you need to enter a secure token. Then the download will continue.

How to get a secure token and How to download RTMP audio/video streams that use secure tokens:

If an RTMP resource you are downloading from requires authorization, Blader will pop up a dialog window shown below where you need to enter the secure token.

Then the download will continue.

How to get a secure RTMP token?
Different policies can be used to authorize RTMP clients. Different analysis is required to find out the tokens depending on the policy used.

The most popular solution is JW player. It supports two kinds of tokens: a dynamic token and a static token. A static token is hard coded into the SWF flash file of the player. Dynamic tokens are sent by server dynamically when playing.

How to get a static secure token for JW Player
To get a secure static token you need to get the .swf file of the player and decompile it. Then you can get the script files of the player and find the keyword "token". For JW Player the static secure token can be found in the RTMPModel.as or player.as.

How to get a dynamic secure token for JW Player
You can get a dynamic secure token by capturing HTTP GET requests coming to the RTMP server. The server returns an XML file like :

<?xml version="1.0"?>
<config>
<file>mp4:00/00/bb/f6</file>
<autostart>true</autostart>
<type>rtmp</type>
<token>be5a0ccc1fcecc10a6b16a7dbf561c1d8dcd87e9a9c7f6f159de8ec392ebc31b</token>
<streamer>rtmp://206.14.141.94/streamer</streamer>
<fullscreen>true</fullscreen>
<stretching>uniform</stretching>
<quality>true</quality>
<skin>http://www.xxx.com/4skin</skin>
<plugins>http://www.xxx.com/related</plugins>
<related>48118</related>
<bufferlength>10</bufferlength>
<bufferthreshold>15</bufferthreshold>
<maxbuffer>60</maxbuffer>
<keyframeinterval>2</keyframeinterval>
<bitrate>576</bitrate>
<displaybufferthreshold>1</displaybufferthreshold>
</config>

Find the token tag in the XML file and copy the token from it. In the example above the token is

be5a0ccc1fcecc10a6b16a7dbf561c1d8dcd87e9a9c7f6f159de8ec392ebc31b

To analyze HTTP GET requests you can use CooJah. It allows you to turn on "XML filter" and "Auto File Detect" function. This allows to capture XML HTTP GET requests. Please not that XML files can b compressed using gzip. Rename compressed files adding the gz extension and decompress them. After that open the decompressed file with a text editor or your browser.

Will this method work for downloading any flash file, even those that cannot be downloaded with Replay Media Catcher (RMC) or GetFLV?

Any software that can capture packets from flash player like Jaksta should be able to record streams protected with secure token.

RMC 3.11 can capture HTTP packets from flash player, but not RTMP packets. Replay Media Catcher 4 can download as well as capture HTTP and RTMP packets from flash player.

So does this program work with Vista x64? When I try to run it, all I get is a message that I need Windows 2000 or something newer.

I can only test it on Windows Vista x32 and Windows 7 x64.

Can anyone confirm that Vista is the problem? Sounds like this could be a useful program and it'd be nice to try it.

CooJah + Blader should be downloaded from the official web-site only. If you have problem with these programs, try to contact the developer.

my download speed is @ 7-8kilobytes/sec for the 8.7MB installation package: this results in a 25mins download. that's the perfect time to bake a pizza and go to the john to finish my reading of Dr. Alan Francis' groundbreaking book Everything Men Know About Women. Good luck on the john!!
