Estimating duration from bitrate, this may be inaccurate Run ffmpeg hevc hw-encoding, here ‘-preset 6’ means ultra-fast mode (the encoding speed is above 200 fps for 1080p), for veryslow mode use ‘-preset 1’ (the encoding speed is around 100fps for 1080p)įfmpeg -hide_banner -y -vsync 0 -s 1920×1080 -i test1080p.yuv -c:v hevc_nvenc -preset 6 -b:v 2M output.h265 First of all you need check that ffmpeg supports nvenc (access to nvidia hw encoder), you merely type ‘ffmpeg’ in the command line and check -enable-nvenc is present in the configuration list:įfmpeg version git-b5f1e05 Copyright (c) 2000-2020 the FFmpeg developersĬonfiguration: -enable-gpl -enable-version3 -enable-sdl2 -enable-fontconfig -enable-gnutls -enable-iconv -enable-libass -enable-libdav1d -enable-libbluray -enable-libfreetype -enable-libmp3lame -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libopenjpeg -enable-libopus -enable-libshine -enable-libsnappy -enable-libsoxr -enable-libsrt -enable-libtheora -enable-libtwolame -enable-libvpx -enable-libwavpack -enable-libwebp -enable-libx264 -enable-libx265 -enable-libxml2 -enable-libzimg -enable-lzma -enable-zlib -enable-gmp -enable-libvidstab -enable-libvmaf -enable-libvorbis -enable-libvo-amrwbenc -enable-libmysofa -enable-libspeex -enable-libxvid -enable-libaom -enable-libgsm -disable-w32threads -enable-libmfx -enable-ffnvcodec -enable-cuda-llvm -enable-cuvid -enable-d3d11va -enable-nvenc -enable-nvdec -enable-dxva2 -enable-avisynth -enable-libopenmpt -enable-amf
