but in this case it´s a mp4 file

Code:

rtmpe://cp71915.edgefcs.net/ondemand/?auth=eaEd_d_d_d_d_d_d_d_d_d_d_d_d_d_d_d_b7a2btdNb lcaaFcWdbdEbidybEcGdMb7-bkopb3-vga-4qoGDqRxmEt&amp;aifp=v006&amp;slist=c1/s/1314116/video.mp4

According to RTMPDump 1.6 Readme by Andrej Stepanchuk:

Quote:

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

Code:

$ flasm -x file.swf

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

Now generate the hash

Code:

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

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

Code:

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

SWF files are cached by your web-browser. You may copy them from there.

You may clear the cache of your web-browser and download SWF files with Replay Media Catcher or Jaksta,...

You may also view the source of a page and find the URL of the SWF file.

i'm just trying to download with rtmpdump. i'm trying to download RTMPE with SWF Verification but i had no luck. i followed all intructions but doesn't work... this is how i trying:

according to rtmpdump's README:

Code:

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...

Code:

name:player3.swf
size:557 kb
 
$ flasm -x player3.swf
 
name=player3.$wf
swfzise=336 kb
 
$ openssl sha -sha256 -hmac "Genuine Adobe Flash Player 001" player3.swf
 
swfhash : HMAC-SHA256(player3.swf)= f8331c93aad6d8c57dd4ab70913697c24a71a28f2d876eda07b70ac20af34460

url: rtmpe://xxxx.mp4
