Automatically Download Subtitles for All Videos in a Directory on Arch Linux

To automatically and recursively download subtitles for all videos in a directory on Arch Linux, you have several options. Here's a comprehensive approach using some of the tools mentioned in the search results:

Using Subliminal

Subliminal is a powerful command-line tool that can recursively search for video files and download subtitles for them[1].

1. Install Subliminal:

sudo pacman -S subliminal

2. Use the following command to download subtitles recursively:

subliminal download -l en /path/to/your/video/directory

Replace "en" with your preferred language code and adjust the directory path as needed.

Using QNapi

QNapi is another excellent option for downloading subtitles[5].

1. Install QNapi:

sudo pacman -S qnapi

2. Use QNapi in console mode to download subtitles recursively:

find /path/to/your/video/directory -type f \( -name "*.mp4" -o -name "*.mkv" -o -name "*.avi" \) -exec qnapi -c {} +

This command finds all video files with .mp4, .mkv, or .avi extensions and passes them to QNapi for subtitle download.

Using yt-dlp

While primarily used for downloading videos, yt-dlp can also download subtitles for local video files[2].

1. Install yt-dlp:

sudo pacman -S yt-dlp

2. Use the following command to download subtitles recursively:

find /path/to/your/video/directory -type f \( -name "*.mp4" -o -name "*.mkv" -o -name "*.avi" \) -exec yt-dlp --write-sub --sub-lang en --skip-download {} +

Replace "en" with your preferred language code.

Using OpenSubtitlesDownload

OpenSubtitlesDownload is a Python script that can be used to download subtitles[3][4].

1. Install OpenSubtitlesDownload:

yay -S opensubtitlesdownload

2. Use the following command to download subtitles recursively:

find /path/to/your/video/directory -type f \( -name "*.mp4" -o -name "*.mkv" -o -name "*.avi" \) -exec OpenSubtitlesDownload.py {} +

Additional Tips

• For all these methods, you may need to adjust the file extensions in the find command to match your video file types.
• Some of these tools may require you to create an account on the subtitle service they use (e.g., OpenSubtitles.org).
• If you encounter rate limiting issues, you may need to add delays between downloads or use a tool that handles this automatically.

Remember to respect copyright laws and the terms of service of the subtitle providers when downloading subtitles.
