drmdecrypt is a tool to decrypt recorded files from Samsung TVs into standard transport stream format. There are multiple similar versions out there based on code from SamyGO and various people but they are all either slow, Windows specific, full of bugs or even all together.

This version is fast, POSIX compliant (Linux, FreeBSD, Windows (MinGW)) and is focused on a small number of useful features.


  • Reading title and channel from .inf file
  • AES-NI support (5x faster)


drmdecrypt [-x] [-o outdir] infile.srf




make install


  • flag to specify verbosity level
  • MPEG packet size could also be 204 or 208 byte
