Not utilizing Nvidia card

[noobtoob4lyfe]

Apologies if this is a noob question, but when I run a movie through BF it makes my cpu usage go to about 90% and my videocard usage remains flat. I ran .\butterflow -d and got the following. Any suggestions? Do I need to add something to the command to activate hardware acceleration? OpenCL devices: Platform : NVIDIA CUDA Platform Vendor : NVIDIA Corporation Platform Version : OpenCL 1.2 CUDA 10.0.132

• Device 0 : GeForce GTX 1080 Ti Vendor Id : 0x10de Version : OpenCL 1.2 Version : 416.34 Work Sizes : 1024, 1024x1024x64 Compatible : Yes

Try using the -device option: butterflow -device 0 <other args>

Thanks very much for the suggestion. I am using that option and the graphics card usage is about the same (somewhere between 3 and 5%). CPU usage is up to 70 -90% though. Is this normal?

It might be selecting the wrong device. Run with -vv to confirm your GPU is being selected.

Thanks again. Here's what it printed out.
butterflow:INFO: Version 0.2.4a4 butterflow:INFO: Cache directory: c:\users\user\appdata\local\temp\butterflow-0.2.4a4 butterflow:INFO: At least one compatible OpenCL device was detected butterflow:INFO: Using device: GeForce GTX 1080 Ti butterflow:INFO: Hardware acceleration is enabled

Maybe ffmpeg needs to have HW acceleration enabled somehow?

I'm not able to get it to leverage my Nvidia GPU either. It detects it fine with -d and the verbose messages says it auto selects the GPU and hardware acceleration is on, but my GPU usage never goes above a few percent.

Here is the verbose output from running `butterflow -r 2x -v video.mp4':

Try using the -device option: butterflow -device 0 <other args>

Thanks you. That's work!

Has anyone apart from NgocSon159 solved this?
