Hi Phyllis, My computer is equipped with a Nvidia GTX-750-Ti video card. It was one of the first two nvidia cards to use the Maxwell architecture. It includes 640 Cuda cores. I use Linux Mint 18.3 Mate 64bit (which is built from a 16.04 kernel from Ubuntu). The nvidia 384.130 driver is installed. I never installed anything particular for the Cuda cores and I don't know if I would be able to successfully install the CUDA Toolkit from https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_... But if I can be useful in testing your development, I'm ready to try. Pierre On 19-06-16 16 h 07, Phyllis Smith wrote:
NVENC/NVDEC for Nvidia graphics board encoding and decoding will automatically be built by way of the configure scripts. But first, before anyone gets too excited, let me just warn you that the ONLY encode codec Nvidia chose to support is H264 and H265 with H265 available on just the latest graphics boards (supposedly at least the ones with the Maxwell chip). Also included in the ffmpeg build is "nvdec" but we have not figured out yet how this affects the hardware acceleration already in place with the use of CIN_HW_DEV=vdpau.
If you have already installed the Cuda software on your computer -- and let me warn you, this is about 3GB of additional space usage -- the default build in the configure script is for cuda is "auto". Otherwise it will NOT be included. Obviously, you must have the Nvdia drivers for your graphics board installed too. Cuda is available to install on your computer only for a specific set of Operating System distros. Go to the following website:
https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_...
and gg says follow the very good set of directions to install around 3 GB. It installs repos by package. Also, install the "fusion repo" -- we do not know if this needs to be installed or not, but all of our test included it.
