  -m, --max-concurrent <number>  max concurrent (default: 2)
  -f, --ffmpeg <file>            path to ffmpeg (default: "ffmpeg")
  -u, --uid <uid>                UID (default: 501)
  -g, --gid <gid>                GID (default: 20)
  -h, --height <height>          scale to height and keep aspect ratio
  -k, --keep                     keep original files
  -l, --log                      create log file
  --hw                           use h264_ni_locan_dec decoder instead of CPU decoder
  --vsync <mode>                 set video sync method [passthrough, cfr, vfr]
  --async                        enable async
  --fps <fps>                    set fps

Examples

node main.js -m 2 -f /usr/local/bin/ffmpeg -h 720 -k -l --hw --vsync vfr --async --aac /mnt/usb/media /mnt/usb/converted/

• 2 concurrent conversions, use /usr/local/bin/ffmpeg, scale to 720p, keep original files, create log file, use h264_ni_locan_dec decoder, set video sync method to vfr, enable async, convert audio stream to AAC, convert all files in /mnt/usb/media and save them to /mnt/usb/converted/.

node main.js -m 1 -f /usr/local/bin/ffmpeg -k -l --vsync vfr --async --aac /mnt/usb/media /mnt/usb/converted/

• one by one conversion, use /usr/local/bin/ffmpeg, keep original files, create log file, use CPU decoder, set video sync method to vfr, enable async, convert audio stream to AAC, convert all files in /mnt/usb/media and save them to /mnt/usb/converted/.

Notes

• uid and gid are only useful if the script runs inside a Docker container.
• use --async if audio is not synchoronized with video (common issue for livestreams recordings).
