There are two GPU-instances types:
g2.2xlarge - 1 x NVIDIA GRID GPU (Kepler GK104) == NVENC
cg1.4xlarge - 2 x NVIDIA Tesla M2050 GPUs == CUDA
In the Wowza Transcoder AddOn Performance Benchmark only two non GPU-instances are tested. Is that because the GPU-instances have not yet been tried or simply don't work with Wowza?
Also, does the following quote mean that only NVENC and not CUDA is supported on Linux?
Wowza Transcoder supports Intel Quick Sync and NVIDIA NVENC accelerated encoding on Windows and Linux and NVIDIA CUDA accelerated encoding on Windows.
