PySceneDetect (https://pyscenedetect.readthedocs.io/en/latest/) running on Debian 10 with Python 3.9.0.
Build on your own:
# docker build github.com/handflucht/PySceneDetect -t pyscenedetect:latest
or pull:
# docker pull handflucht/pyscenedetect
PySceneDetect is set as Entrypoint:
# docker run pyscenedetect -h
Usage: scenedetect [OPTIONS] COMMAND1 [ARGS]... [COMMAND2 [ARGS]...]...
For example:
scenedetect -i video.mp4 -s video.stats.csv detect-content list-scenes
Note that the following options represent [OPTIONS] above. To list the
optional [ARGS] for a particular COMMAND, type `scenedetect help COMMAND`.
You can also combine commands (e.g. scenedetect [...] detect-content save-
images --png split-video).
Options:
-i, --input VIDEO [Required] Input video file. May be specified
multiple times to concatenate several videos
together.
-o, --output DIR Output directory for all files (stats file, output
videos, images, log files, etc...).
-f, --framerate FPS Force framerate, in frames/sec (e.g. -f 29.97).
Disables check to ensure that all input videos have
the same framerates.
-d, --downscale N Integer factor to downscale frames by (e.g. 2, 3,
4...), where the frame is scaled to width/N x
height/N (thus -d 1 implies no downscaling). Each
increment speeds up processing by a factor of 4 (e.g.
-d 2 is 4 times quicker than -d 1). Higher values can
be used for high definition content with minimal
effect on accuracy. [default: 2 for SD, 4 for 720p, 6
for 1080p, 12 for 4k]
-fs, --frame-skip N Skips N frames during processing (-fs 1 skips every
other frame, processing 50% of the video, -fs 2
processes 33% of the frames, -fs 3 processes 25%,
etc...). Reduces processing speed at expense of
accuracy. [default: 0]
-s, --stats CSV Path to stats file (.csv) for writing frame metrics
to. If the file exists, any metrics will be
processed, otherwise a new file will be created. Can
be used to determine optimal values for various scene
detector options, and to cache frame calculations in
order to speed up multiple detection runs.
-v, --verbosity LEVEL Level of debug/info/error information to show.
Setting to none will suppress all output except that
generated by actions (e.g. timecode list output). Can
be overriden by `-q`/`--quiet`.
-l, --logfile LOG Path to log file for writing application logging
information, mainly for debugging. Make sure to set
`-v debug` as well if you are submitting a bug
report.
-q, --quiet Suppresses all output of PySceneDetect except for
those from the specified commands. Equivalent to
setting `--verbosity none`. Overrides the current
verbosity level, even if `-v`/`--verbosity` is set.
-h, --help Show this message and exit.
Commands:
about Print license/copyright info.
detect-content Perform content detection algorithm on input video(s).
detect-threshold Perform threshold detection algorithm on input video(s).
help Print help for command (help [command]).
list-scenes Prints scene list and outputs to a CSV file.
save-images Create images for each detected scene.
split-video Split input video(s) using ffmpeg or mkvmerge.
time Set start/end/duration of input video(s).
version Print version of PySceneDetect.
Analyzing video at /some/path/video.mp4 and saving each scene to a separate file:
# docker run -v /some/path:/video:z pyscenedetect:latest -i /video/video.mp4 -o /video/ detect-content split-video
