This library uses ffmpeg to extract an audio track from a video file. The audio can also be separated by chapter, if the chapters are annotated in the video.
$ pip3 install video2audioThe ffmpeg and ffprobe commands must be available on your system (and PATH).
from video2audio import AVFile
f = AVFile('/path/to/some/movie.mkv')
# Extract the entire audio track as a single mp3:
f.extract_audio('/path/to/some/audio_only.mp3', chapter=None)
# Extract the second, entire audio track as a single mp3:
f.extract_audio('/path/to/some/audio_only_second_stream.mp3', chapter=None, stream=1)
# Extract each chapter to a separate mp3 file:
f.extract_all_chapters_audio('/path/to/chapter/outputs/')
# Extract each chapter to a separate mp3 file, manually naming them:
f.extract_all_chapters_audio(
'/path/to/chapter/outputs/',
output_filenames=['ch1_title.mp3', 'ch2_title.mp3', 'ch3_title.mp3']
)
# Extract only chapter number 12 (or 13, using 1-indexing):
chapter_list = f.get_chapters()
f.extract_audio('single_chapter.mp3', chapter=chapter_list[12])Extract the second audio track using the command line tool:
$ video2audio -t 1 /path/to/some/movie.mkv /path/to/chapter/outputs/video2audio -h will explain the other options.
