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 I recently downloaded a program by the name of 'Wondershare video converter ultimate' in order to convert 1080p videos into 4k, and as I was converting four files at the same time the temperatures of the CPU were alternating between mid to high 90C and 100C. Sample decode using CUVID: ffmpeg -c:v h264_cuvid -i input outputįull hardware transcode with NVDEC and NVENC: ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i input -c:v h264_nvenc -preset slow output Sample decode using CUDA: ffmpeg -hwaccel cuda -i input output The note about missing ffnvcodec from NVENC applies for NVDEC as well. The full set of codecs being available only on Pascal hardware, which adds VP9 and 10 bit support. They differ in how frames are decoded and forwarded in memory. Note that FFmpeg offers both NVDEC and CUVID hwaccels. Codec support varies by hardware (see the GPU compatibility table). NVDEC offers decoders for H.264, HEVC, MJPEG, MPEG-1/2/4, VP8/VP9, VC-1. Note: If you get the No NVENC capable devices found error make sure you're encoding to a supported pixel format. You can see available presets, other options, and encoder info with ffmpeg -h encoder=h264_nvenc or ffmpeg -h encoder=hevc_nvenc. Usage example: ffmpeg -i input -c:v h264_nvenc -profile high444p -pixel_format yuv444p -preset default output.mp4 This means that running the following before compiling ffmpeg should suffice: git clone FFmpeg will look for its pkg-config file, called ffnvcodec.pc.

It has a working Makefile with an install target: make install PREFIX=/usr. If you get an error from configure complaining about missing ffnvcodec, this project is what you need. Note: FFmpeg uses its own slightly modified runtime-loader for NVIDIA's CUDA/NVENC/NVDEC-related libraries. The NVIDIA Codec SDK or compiling FFmpeg with -enable-cuda-llvmįfmpeg configured with -enable-nvenc (default if the drivers are detected while configuring) Supported drivers for your operating system In order to enable it in FFmpeg you need:

FFmpeg supports NVENC through the h264_nvenc and hevc_nvenc encoders. NVENC can be used for H.264 and HEVC encoding. They can be used for encoding and decoding on Windows and Linux. NVENC and NVDEC are NVIDIA's hardware-accelerated encoding and decoding APIs. (yes, you can do both decoding and encoding with your nvidia graphics card) if you have more than one graphics card, you can change the number. This is what worked for me: (NVIDIA GTX 1650 SUPER) ffmpeg -hwaccel_device 0 -hwaccel cuda -i 'input.mkv' -c:v h264_nvenc -preset slow 'output.mp4'ĭevice is set to 0 because that is the first GPU in your computer.
