get-keyframes

extract keyframes from a video file

useful to sync audiotracks between multiple video files



usage

curl --remote-name --no-clobber --fail --retry-all-errors --retry 20 "$(curl --get --data-urlencode video_path="/cas/btih/104ff3a06a3910c2cd5ba86ccaf8a4ba04c14ec0/Scary.Movie.2000.German.800p.microHD.x264-RAIST/Scary.Movie.2000.German.800p.microHD.x264-RAIST.mkv" --data-urlencode nth_keyframe=4 --data-urlencode downscale_factor=2 http://milahu.duckdns.org/bin/get-keyframes)"

why

because my upload is slow = only 40 Mbit/s = 5 MByte/s
because keyframes are 10x smaller than video files



options

nth_keyframe
select every nth keyframe
higher value = smaller output file
default value: 4
valid values: (1, 2, 4, 8)

downscale_factor
downscale the video width and height
dst_width = src_width / downscale_factor
higher value = smaller output file
default value: 2
valid values: (1, 2, 4, 8)
