To do hardware encoding, you must prepare the module and build ffmpeg yourself. (On Linux Mint, installing ffmpeg as a package from apt made NVENC available.) ) The default ffmpeg is software encoding only. Main monitor is connected to Intel GPU (when NVIDIA GPU is also present).Ffmpeg allows hardware encoding using Intel's QSV, AMD's AMF, and NVIDIA's NVENC.Intel Core i7 Gen 6 (iGPU: Intel HD Graphics 530).FFmpeg version 5.0.1-full_build-Hardware configuration used for testing:.

Windows 10, with updated Intel HD Graphics driver.

The h264_qsv decoder does not support yuv444p pixel format (at least not with my hardware).įor making sure that the pixel format is yuv420p, build input.mp4 file (for testing):įfmpeg -y -f lavfi -i testsrc=size=320x240:rate=10:duration=10 -vcodec libx264 -pix_fmt yuv420p input.mp4 The following command works (for specific hardware and software configuration):įfmpeg -y -init_hw_device qsv=hw,child_device_type=dxva2 -hwaccel qsv -hwaccel_output_format qsv -c:v h264_qsv -i input.mp4 -vf "vpp_qsv=framerate=60,scale_qsv=w=640:h=480" -c:v h264_qsv output.mp4 I'm on a computer with an Intel 11th gen i5-1135G7, which I know supports the QSV encoders. No such filter: 'scale_qsv=w=1920:h=1080'įailed to inject frame into filter network: Invalid argumentĮrror while processing the decoded data for stream #0:0 Please explicitly set device type via "-init_hw_device" option. This behaviour will be removed in the future. This is the output I got: WARNING: defaulting child_device_type to AV_HWDEVICE_TYPE_DXVA2 for compatibility with old commandlines.
