How to use rtmpdump? I don't understand it. Can someone post instructions?

[Stream Recorder]

In Windows Run Command Prompt, go to the directory with rtmpdump.exe using cd command and run rtmpdump.exe .

rtmpdump basic usage

rtmpdump -r "rtmp://host/dir/file.flv" -o filename.flv

rtmpdump parameters

--help|-h               Prints this help screen.
--rtmp|-r url           URL (e.g. rtmp//hotname[:port]/path)
--host|-n hostname      Overrides the hostname in the rtmp url
--port|-c port          Overrides the port in the rtmp url
--protocol|-l           Overrides the protocol in the rtmp url (0 - RTMP, 3 - RTMPE)
--playpath|-y           Overrides the playpath parsed from rtmp url
--swfUrl|-s url         URL to player swf file
--tcUrl|-t url          URL to played stream (default: "rtmp://host[:port]/app")
--pageUrl|-p url        Web URL of played programme
--app|-a app            Name of player used
--swfhash|-w hexstring  SHA256 hash of the decompressed SWF file (32 bytes)
--swfsize|-x num        Size of the decompressed SWF file, required for SWFVerification
--auth|-u string        Authentication string to be appended to the connect string
--flashVer|-f string    Flash version string
--live|-v               Save a live stream, no --resume (seeking) of live strems possible
--flv|-o string         FLV output file name, if the file name is - print stream to stdout
--resume|-e             Resume a partial RTMP download
--timeout|-m num        Timeout connection num seconds 
--buffer|-b             Buffer time in milliseconds, this option makes only sense in stdout mode 
--skip|-k num           Skip num keyframes when looking for last keyframe to resume from. Useful if resume fails

SWF Verification
Download the swf player you want to use for SWFVerification, unzip it using

$ flasm -x file.swf

It will show the decompressed filesize, use it for --swfsize

Now generate the hash

$ openssl sha -sha256 -hmac "Genuine Adobe Flash Player 001" file.swf

and use the --swfhash "01234..." option to pass it. e.g.

$ ./rtmpdump --swfhash "123456..." --swfsize 987...

i know that. Im talking about how can i download a rtmp stream.
Do i need any other programs to find the links or anything.

[Stream Recorder]

Yes, you need other programs to find RTMP URLs, find RTMPE stream URLs.

You may also need to find additional parameters. Sometimes you can find them from the source of the web-page. You can also use two additional server programs, rtmpsrv and rtmpsuck that come with rtmpdump 2.1:

rtmpsrv is a stub for a server; it logs the connect and play parameters from a regular client that connects to it. These parameters can then be used with rtmpdump to retrieve a stream.

rtmpsuck is a transparent proxy; it intercepts connections from a client and then makes an outbound connection to the real server. After all handshaking is complete and encryption keys with both sides are negotiated, it records the cleartext stream data into files while relaying the data from the server to the client.

i have the urls now what?

Also i found a new program called flazr
I don't know how to use that either maybe you can help.

Tutorial on using rtmpdump:

Originally Posted by constantcuriousity.blogspot.com

Today I attended a lecture/demo session on "hacking" various media sites like YouTube, Hulu, last.fm. Essentially it was a practical demonstration of the cat and mouse game hackers play with content pedlars on the internet....

One of the tools mentioned was rtmpdump ...

I decided to compile it myself from the most recent development version. If you're lazy and brave enough to trust compiled binaries and packages from third parties, go to LinuxCentre and install flvstreamer for your operating system. These programs were once one and so far they use the same commands. Read: they work the same.
(Editor's note: flvstreamer doesn't support RTMPE secure streams)

These instrucitons work on Ubuntu 9.10 (karmic) but please be aware things change rapidly so the following might not work forever.

First of all install the tools needed for accessing the code and compilation.

sudo apt-get install build-essential gcc make subversion libssl0.9.8 libssl-dev libssl0.9.8

Now check out the latest code from the Subversion repository:

svn co svn://svn.mplayerhq.hu/rtmpdump rtmpdump

If you prefer a stable version, run this instead:

wget http://rtmpdump.mplayerhq.hu/rtmpdump-1.9.tgz
tar xfz rtmpdump-1.9.tgz
mv rtmpdump-1.9 rtmpdump

I'm sure the impatient are looking forward to completing this ASAP so here's the final step in setting up rtmpdump on your computer:

cd rtmpdump
make linux

The program now lies in the same folder and you can only run it by telling your shell (like bash) exactly where it is. If you're in the same folder, running it is as simple as ./rtmpdump but ./ is only short for the current folder and it gets expanded to (in my case) /home/jasa/rtmpdump/rtmpdump.

Great! Now we need a media site which uses a Adobe's RTMP server. I think I won't get in trouble if I use VideoLectures.net as an example.

Lets say I'm interested in probability and statistics. And I want to watch these lectures offline, on a train or wherever.

Unfortunately this isn't a straightforward process and quite a bit of work is required. It is derived from a mailing list thread.

I need to see the source code of the web page above, not the rendered output of the web browser. In Firefox press Ctrl+U. Now I need some hard data to pass to rtmpdump. Search for a javascript section which launches the flash video player. For the statistics video this is the interesting section:

var flashvars = {
     
streamer: "rtmp://oxy.videolectures.net/video",
file: "2007/pascal/bootcamp07_vilanova/keller_mikaela/bootcamp07_keller_bss_01.flv",
     
height: '288',
autostart: "true",
bufferlength: '5',


image: "http://media.videolectures.net/play.png",
  
id: "FlvPlayer" // last line, no colon ',' !
};
swfobject.embedSWF("http://media.videolectures.net/jw-player/player.swf", "video_embed", "384", "307", "9.0.0", "http://media.videolectures.net/swfobject/expressInstall.swf", flashvars, params, attributes);

Generally searching (Ctrl+F) for flashvars should get you near the required data. The line swfobject.embedSWF(...) causes the video player to load inside your browser and display the correct media. This media rests on a different server than the webpage and I will use rtmpdump to connect to that server instead of the flash player. Now Adobe has put some roadblocks into the process but lucky for me I have a flying car.

I'll just give you the final command now and explain later!

./rtmpdump -r rtmp://oxy.videolectures.net/video/ -y 2007/pascal/bootcamp07_vilanova/keller_mikaela/bootcamp07_keller_bss_01 -a video -s http://media.videolectures.net/jw-player/player.swf -w ffa4f0c469cfbe1f449ec42462e8c3ba16600f5a4b311980bb626893ca81f388 -x 53910 -o test.flv

The -r switch requires an argument which is the URL of the media server and is found in the variable streamer in the JavaScript source code above.

The -y switch needs the playpath and that is found in the JavaScript variable file, (minus the extension .flv or .mp4).

The -a switch is the name of the used player and usually automatically inferred from the URL. Defining it manually works by copying the part after the server name in the streamer.

The -s switch defines the flash video player which normally connects to the media server. In the example it is the first argument of the function embedSWF.

Here's where things get even more complicated. The media server wants some extra data about this player, specifically its sha256 hash-sum and size in bytes. So lets get them:

wget http://media.videolectures.net/jw-player/player.swf
sha256sum player.swf
ls -l player.swf

Supply the sha356sum to switch -w and the file size to the -x switch.

Anything else? Yeah, I need to specify where to save the video with -o.

Run the longest command ever and get yourself a beer (you've earned it)!

I admit that doing this for every video gets time consuming but unfortunately it is a procedure specific to every site. Look at the mailing list thread link again to see different javascript:

[compn]

here is a command line using mtv's website as an example:

rtmpdump.exe  --swfhash 1155163cece179766c97fedce8933ccfccb9a553e47c1fabbb5faeacc4e8ad70 --swfsize 563963 --swfUrl "http://media.mtvnservices.com/player/release/?v=3.14.0" -r rtmp://cp10740.edgefcs.net/ondemand/mtvcomstor/_!/mtv.com/onair/the_stew/comp_reel/mt_71824_stew_26_320.flv -o mt_71824_stew_26_320.flv

to find the rtmp url i used URL Snooper
the swfhash and swfsize were generated by:

Download the swf player you want to use for SWFVerification, unzip it using

$ flasm -x file.swf

It will show the decompressed filesize, use it for --swfsize

Now generate the hash

$ openssl sha -sha256 -hmac "Genuine Adobe Flash Player 001" file.swf

and use the --swfhash "01234..." option to pass it.

e.g. $ ./rtmpdump --swfhash "123456..." --swfsize 987...

For rtmpdump users,
New RTMPE and SWF Auth method was released from Adobe.

Does anyone can get this hyper protected flv by using rtmpdump ?

How to download flash video RTMP/RTMPE streams with freeware rtmpdump and URL Snooper.

1. Start URL Snooper select the the "General Options" tab and click "Auto Determine Network Adapter Now" or choose the Network Adapter manually.
   
   
   
   
2. Select the "Search" tab and paste the url to your video page at the bottom. Then press the "Download" button.
3. Search for RTMP or RTMPE in the "Protocol" column.
4. Right click on the URL and select "Copy selected URL (Strip all args)".
   
   
   
   If you don't find any RTMP streams then click on the "Sniff Network" button in the URL Snooper and start playing your video stream in your browser. Wait until you see an RTMP link.
   
5. After you copying the RTMP/RTMPE URL, use the RTMPDump command line tool. Download rtmpdump.exe and save it into the C:\rtmpdump folder, for example. Then start the "Command Prompt" (Start->Programs->Accessories->Command Prompt) and in the command line type:
   

   "C:\rtmpdump\rtmpdump.exe" -r "rtmpe://fl11.c90909.cdn.qbrick.com/90909/_definst_/kluster/20091027/geose_PG-1131239-010A-TRUEBLOOD1" -o "c:\downloads\video.flv"

   and replace the "rtpme://"-stream with the one you copied from URLSnooper. Right click in the command prompt to Paste.
   
   
   
   
6. If it works, RTMPDump will start downloading the RTMP/RTMPE video stream and will save it as "c:\downloads\video.flv"
   
   
   

Please note that RTMP/RTMPE streams that use SWF Verification are supported by rtmpdump, but you need to provide some additional parameters.

SWF Verification and rtmpdump 2.1
Unlike previous versions, rtmpdump 2.1 can compute hash/size of an SWF player automatically. You don't need to download the player, unpack it and compute its hash anymore. Just provide the URL to the SWF player by using the -W parameter:

--swfVfy|-W url         URL to player swf file, compute hash/size automatically
