extract-subtitles

Extract subtitles from a video file and save them as .srt file(s)

Usage

Make sure the script is executable (chmod +x extract_subtitles.sh).

Let's assume you have a video file some_video.mkv which has the two subtitle streams Dialogue and Signs & Songs in English.

./extract_subtitles.sh some_video.mkv

This will create the files some_video.Dialogue.eng.srt and some_video.Signs and Songs.eng.srt

To extract subtitles for all .mkv files in the current folder you can use the following find command:

find . -name '*.mkv' -exec ./extract_subtitles.sh {} \;

Note: Ampersands (&) are replaced by the word "and" and non-alphanumeric characters except spaces and (, ), [, ],.,-,_ are removed. Multiple consecutive whiespaces are replaced by a single space. The script has to be executed with bash.
