According to the documentation; NVENC should be available when running Wowza as a Windows service. (ref: How to enable hardware-accelerated transcoding when running as a Windows service)Drivers for NVIDIA NVENC and NVIDIA Tesla GPU hardware are structured in a way such that the hardware acceleration capabilities are available to applications running in Session 0 Isolation.
But when I start the Windows service, start a stream that has the Transcoder Add On enabled, the log tells me "NVidia hardware acceleration is NOT available". And when I start Wowza from the desktop, it works ("NVidia NVENC hardware acceleration is available; GPU: name:"Quadro K4200" version:3.0 driver:6050 ... etc")
How can I make NVENC available even when Wowza is running as a Windows service?
