DVB-C CAM descramble, works with gnutv but not in VLC?
Posted: 29 Nov 2013 09:27
I have a DVB-C tuner card with a CAM module + subscription card. I've made a channels.conf file with the scan command.
When I open this file with VLC ( 2.0.8 ) it can show the free channels, but not the scrambled ones.
Gnutv will successfully decode the scrambled channels using the same channels.conf, and I can stream it to VLC. (Gnutv won't let me change channels without restarting it though, unless I patch it. But then, VLC often cannot handle when the gnutv stops and starts the TS stream.)
I see in the vlc log that it finds no descrabmlers. Do I need to configure something else in VLC, or is this functionality just not implemented/broken?
