Selected ratecontrol mode is not supported by the QSV runtime. If encoding stuck or the following weird messages printed: To encode HEVC/H.265 by QSV hw-encoder you need instruct ffmpeg to use hw-accelerator 'qsv' by '-hwaccel qsv', apply HEVC hw-encoder by 'c:v hevc_qsv', in addition you need load hevc plugin (see the example command line).įfmpeg -hwaccel qsv -s 1920x1080 -pix_fmt yuv420p -i test420p.yuv -c:v hevc_qsv -load_plugin hevc_hw -b 10M -y test.h265 check that your Intel GPU supports HEVC/H.265 encoding and decoding by visiting the following site:Ĭheck whether your ffmpeg supports QSV with '-hwaccels' option (if not try to reconfigure and re-compile it), i get the following print :įfmpeg version N-91655-g7e0df5910e Copyright (c) 2000-2018 the FFmpeg developersĬonfiguration: -enable-gpl -enable-version3 -enable-sdl2 -enable-fontconfig -enable-gnutls -enable-iconv -enable-libass -enable-libbluray -enable-libfreetype -enable-libmp3lame -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libopenjpeg -enable-libopus -enable-libshine -enable-libsnappy -enable-libsoxr -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-libvorbis -enable-libvo-amrwbenc -enable-libmysofa -enable-libspeex -enable-libxvid -enable-libaom -enable-libmfx -enable-amf -enable-ffnvcodec -enable-cuvid -enable-d3d11va -enable-nvenc -enable-nvdec -enable-dxva2 -enable-avisynthīy the way you can disable printing ffmpeg banner by -hide_banner:
