copy attached file to your usb or somwhere in the TV

chmod 777 drmdecrypt

your recorded files should be on /dtv/usb/sdx/CONTENT/

you need to know whitch recoeded file (xxxxxxxxxx.srf) is asiciated with player browser file

1. start smaygo ext app
2. enable drm engine with SamyGO DRM Switcher
3. start playing file you want to decrypt on TV!
execute :

drmdecrypt /dtv/usb/sdx/CONTENT/xxxxxxxxxxx.srf /dtv/usb/sdx/CONTENT/xxxxxxxxxxx.ts, depends of file size and as tty is disabled on D serie , you need wait until mesage come :

Code: Select all

drmdecrypt successfull done...!
the tool should also work on c serie.

tested on UE32D6500.

// Edit ON 25.11.2011
Fixed > 2Gig Size bugfix endless loop while decrypting > 2gig streams
T-GAPxxx suport
added drmget tool to extract needed key for non arm platform
added source code and build for x86 linux


for use outside of TV
it is need to extract drm key whitch is need to descramble whole content
by copy drmget into tv, same procedure is need like explained with drmdecrypt tool, start playing(just short time 1-2-3 seconds) your content while DRM is enabled, execute drmget with parameter of file xxxxxxxxxx.key or without any parameter , key file will be created in the dir in case if no parameter given, file will be "drm.key"

copy .srf file out of tv/usb and execute drmdecrypt_x86 xxxxxxxxx.srf drm.key or rebulid sources to any other platform you wish.

Hi denny. I don't even get that far, seems it fails to read key:

./drmdecrypt /dtv/usb/sda1/CONTENTS/20111123205013.srf /dtv/usb/sda1/CONTENTS/test.ts

gooseye check that you have enabled drm and start short playing the content, then run command...

Yep, I double checked that the recording was actually made with drm, next re-enabled drm on TV, start playback of same content on TV & then run your decrypt tool. Always key 00 00...
