Cannot compile OpenCV 3. Examples include using NCCL in different contexts such as single process multiple threads and multiple processes potentially across different machines. Instead we only ask it to use VideoToolBox then the OS will assign the associate GPU to handle the decoding encoding work. There are some proprietary encoders that utilize the GPU but that does not mean they are well optimized though encoding time may be faster and they might be worse than x264 anyway and possibly slower. So if you were to use a Pascal GRID GPU you can use CUDA with all vWS profiles. Fast SSDs make a big difference one with the source files second as the destination.
