Easily split video files with the help of a docker container and ffmpeg.

It's a chore to properly install ffmpeg and all the codecs, and it's also not very easy to split video files. So that's why this image was created.

Usage

    docker run -it --rm  \
    -u "your-user-id" \
    -v /directory-with-video:/tmp/video-in \
    -v your-output-directory:/tmp/video-out \
    ivandotv/ffmpeg-split-video "split" "big-video-file.avi" 4

• run command can work without mounting the output directory, in that case newly created video files will be put in the same directory as the original video file.
• Default split is 2 (example uses 4).
• You can also call ffmpeg or ffprobe directly (instead of "split")
• When video file is split, it's not re-encoded.

Actual command line parameters that are going to be passed to ffmpeg binary are:

ffmpeg -i "big-video-file" -ss (start time) -to (end time ) -acodec copy -vcodec copy "output-file-directory"

Helper script

There is also a helper script (./tools/split-video) that is used as a wrapper for the split functionality of the container. You can put it somewhere in your $PATH so you can call it from everywhere.

Use it like this:

split-video video_file [number_of_parts] [output_folder]

The script will launch the container, and pass all the required parameters for the split functionality (mounting volumes, passing correct arguments etc...)
