I have encountered error when outputting NotchLC video to Video Device Out with GPU Direct transfer mode. I am using Blackmagic as output device. When I activate output, NotchLC decoding either stops, or Video Device Out TOP produces error
Failed to setup GPU Direct. Try changing the Transfer Mode parameter. When using Asynchronous transfer mode (or different video codec) everything works as expected (tested on Win 10, TD 2020.22080, Desktop Video 11.5, NVIDIA driver 442.74).
