• First you have to create a m3u playlist with your favorite program.
• Then run my-mpv to create a my-mpv playlist file:

my-mpv -w 1980 -v 1080 -c mpv_conf_file -p playlist.m3u

• Then you have to create a trained svm. For that you can use: train_img_info_classifier or the same compress-h265 with -t option (usage instructions missing)
• Then Compress!

killall ffmpeg; compress-h265 -d qsv -e hevc_qsv --ml nb.conf --delete --replace -y 1080 -c mpv_config_2020.08.19 -p list_2020.08.19.m3u -r report-`date +%s`

killall ffmpeg; compress-h265 -d cuda -e hevc_nvenc --ml nb.conf --delete --replace -y 1080 -c mpv_config_2020.08.19 -p list_2020.08.19.m3u -r report-`date +%s`

Remember that you can only use gpus that support h265 hardware accelerated compression:
