[App] srf decrypt for HKMFK/JZM

Command line tool to convert a .srf file to decrypted .ts file. I only tested it on HKMFK so no idea if it works on other firmware types.

Install:
- copy srf_decrypt from the zip to the tv (i.e. $SYSROOT/usr/bin)
- add exec attribute if necessary (chmod 755 $SYSROOT/usr/bin/srf_decrypt)

Usage:

Code: Select all

# srf_decrypt <full_path_to_srf_file>
ex: srf_decrypt /opt/storage/usb/sda2/CONTENTS/19700101022506.srf
Output:
- a new .ts file will be created in the same directory containing the .srf file. Make sure enough free space is available.

Change log:
SpoilerShow
- v0.1 - First release
- v0.2 - Fixed support for files larger than 2Gb

At first I thought "but!? we already have got drmdecrypt and ffmpeg?! Yet another faster one?"... You should have told that one doesn't need prior key :)
I confirm works as well on T-JZM.
Btw, SYSROOT is full exec (at least released one), no need for chmod

Yes, on K there is no key dumper so I wasn't able to make drmdecrypt nor ffmpeg work here. :)
Thanks for testing on T-JZM.

Actually there is a keydumper, read carefully at the end of root procedure, you just have to take it from J sysroot.
At least your stuff is not copyrighted, will include. Thanks for sharing it :)

tzpvrdmpkeys from J doesn't work here :cry: I though that's why it wasn't included on K

Code: Select all

localhost~ # tzpvrdmpkeys
Tizen PVR key dumper v0.2.0 - (c) bugficks 2016

[E] dlopen error libpvr_drm_client.so.0: cannot open shared object file: No such file or directory

First news to me, not easy to be aware when nobody reports nothing (works on JZM). One more good reason to include in next sysroot version ;)

Bon appétit !

I've just added optional destination filename for srf_decrypt to be compliant with srf2ts.sh ts naming.
K sysroot now updated and including it :) (cf. changelog)

Great! I like the srf2ts.sh ts naming way more than the default "timestamp" srf names :D
