Get some information from *.inf files
Posted: Sun Dec 11, 2011 8:57 pm
I've written a very tiny C program to get some information from the *.inf files of PVR records. This may be usefull, e.g., to find the *.srf file you want to decrypt ("Samsung PVR Content Decrypting tool - final "). Here's the source:
You may compile it using
I've tried it out with gcc 4.5.0 at Linux x86_64. Maybe cross compilation for arm7 would be possible (don't know how to do this).
