Before those changes iCAM channels didnt clear.
I dont know if it was specifically that patch, but it was around a year or so ago.
My point is its not OScam or Ncams fault that e2 users require that stream relay crap.
Other dvb-s software made changes to support iCAM without issue.
With e2 being able to descramble iCAM using a custom oscam binary with streamrelay proves that the hardware and drivers are capable.
It seems to me that the core e2 libraries need to be updated to support iCAM since it breaks the dvb standard.
