I have managed to get a similar method as the Enigma2 / Oscam-emu stream relay working on a linux pc. I am using an old skystar2 pci card (dvb-s only) and use MuMuDVB as a streaming server to feed Osemu stream relay. Then you can connect to Osemu with a client (vlc, stb, etc) to view the decrypted channels. (I can post details if anyone is interested...)
But, this is really just a hack and not a real solution. So, I am looking into two options:
1. Modify Osemu (more likely oscam with emu patch) to use the dvbloopback method instead of using a stream relay.
2. Modify FFdecsawrapper to include code for powervu decryption. (http://www.lursen.org/wiki/FFd…nd_Oscam_on_Debian/Ubuntu
If anyone knows of anyone else already working on this (or some other approach) please let me know before I re-invent the wheel...
