From what I understand hevc_v4l2m2m is the hardware method to encode in M1, but the testįfmpeg -i vid0.avi -c:v hevc_v4l2m2m vid1.mp4

The only one that worked was libx265 (software encoding), which expectedly is too slow. hevc_vaapi H.265/HEVC (VAAPI) (codec hevc) hevc_v4l2m2m V4L2 mem2mem HEVC encoder wrapper (codec hevc) hevc_nvenc NVIDIA NVENC hevc encoder (codec hevc) nvenc_hevc NVIDIA NVENC hevc encoder (codec hevc) libx265 libx265 H.265 / HEVC (codec hevc) Ibdrm -enable-libiec61883 -enable-chromaprint -enable-frei0r -enable-libx264 -enable-shared Nable-libmp3lame -enable-libmysofa -enable-libopenjpeg -enable-libopenmpt -enable-libopus -enable-libpulse -enable-librsvg -enable-libruīberband -enable-libshine -enable-libsnappy -enable-libsoxr -enable-libspeex -enable-libssh -enable-libtheora -enable-libtwolame -enablĮ-libvidstab -enable-libvorbis -enable-libvpx -enable-libwavpack -enable-libwebp -enable-libx265 -enable-libxml2 -enable-libxvid -enablĮ-libzmq -enable-libzvbi -enable-lv2 -enable-omx -enable-openal -enable-opencl -enable-opengl -enable-sdl2 -enable-libdc1394 -enable-l Ibcodec2 -enable-libflite -enable-libfontconfig -enable-libfreetype -enable-libfribidi -enable-libgme -enable-libgsm -enable-libjack -e
