GPU-accelerated video processing with ffmpeg

Question

I want to use ffmpeg to accelerate video encode and decode with an NVIDIA GPU.

From NVIDIA\'s website:

NVIDIA GPUs contain one or more hardwa

Answer 1

Quick use on ​supported GPU:

CUDA

ffmpeg -hwaccel cuda -i input output

CUVID

ffmpeg -c:v h264_cuvid -i input output

Full hardware transcode with NVDEC and NVENC:

ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i input -c:v h264_nvenc -preset slow output

If ffmpeg was compiled with support for libnpp, it can be used to insert a GPU based scaler into the chain:

ffmpeg -hwaccel_device 0 -hwaccel cuda -i input -vf scale_npp=-1:720 -c:v h264_nvenc -preset slow output.mkv
