hello, how does one select which GPU to use for hardware acceleration when more than 1 GPU is installed in the system?
some searching seemed to hint at using the -gpu option but it looks like that option has been deprecated? the option does not appear in the man pages or on the documentation pages on the ffmpeg website. trying to use the option seems to fail. thank you $ ffmpeg -i test.mov -c:v h264_videotoolbox -gpu 1 test.mp4 ffmpeg version N-107303-g9fec43a92d Copyright (c) 2000-2022 the FFmpeg developers built with Apple clang version 13.1.6 (clang-1316.0.21.2.5) configuration: --enable-static --enable-pthreads --enable-version3 --cc=clang --host-cflags= --host-ldflags= --enable-ffplay --enable-gnutls --enable-gpl --enable-libaom --enable-libbluray --enable-libdav1d --enable-libmp3lame --enable-libopus --enable-librubberband --enable-libsnappy --enable-libtesseract --enable-libtheora --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libxvid --enable-lzma --enable-libfontconfig --enable-libfreetype --enable-frei0r --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libspeex --enable-libsoxr --disable-libjack --disable-indev=jack --enable-libcaca --extra-libs=-liconv --prefix=/opt/miniconda3 --enable-macos-kperf --enable-libkvazaar --disable-shared --pkg-config-flags=--static --enable-neon --enable-nonfree --enable-runtime-cpudetect --enable-postproc --enable-libfdk_aac libavutil 57. 27.100 / 57. 27.100 libavcodec 59. 36.100 / 59. 36.100 libavformat 59. 26.100 / 59. 26.100 libavdevice 59. 6.100 / 59. 6.100 libavfilter 8. 41.100 / 8. 41.100 libswscale 6. 6.100 / 6. 6.100 libswresample 4. 6.100 / 4. 6.100 libpostproc 56. 5.100 / 56. 5.100 Unrecognized option 'gpu'.
