"""
Return audio track information from a media file or DVD title.
When ``handbrake`` is True, audio tracks are detected using
HandBrakeCLI's scan output. This is useful for DVDs and other
optical media sources where ffprobe may provide incomplete track
information.
When ``handbrake`` is False, ffprobe is used to inspect the media
file and return all audio streams.
Args:
source:
Path to the media file or DVD device/directory.
title:
DVD title number to scan when using HandBrakeCLI.
Ignored when using ffprobe.
handbrake:
If True, use HandBrakeCLI for track detection.
If False, use ffprobe.
Returns:
List of dictionaries containing:
- number: audio track number/index
- description: language, title, or track description
Example:
get_audio_tracks("movie.mkv")
[{'number': 1, 'description': 'eng'}]
get_audio_tracks("/dev/dvd", title=1, handbrake=True)
[{'number': 1, 'description': 'Deutsch'}]
