Script to recursively sync (using Subsync) all the subtitles of a folder and overwrite the old one (after backing it up). It won't try to sync previously synced subs on next iterations.

Subsync is an awesome library, I highly recommend you to check out its repository:

History about it:

"The implementation for this project was started during HackIllinois 2019, for which it received an Honorable Mention (ranked in the top 5 projects, excluding projects that won company-specific prizes)."

• Python 3.6+
• Subsync

python rSubsync.py --lang xx --path /path Only the lang is required. It needs to match the lang specified on your subtitle files, so:

If your subtitles are named like: subtitle.en.srt the lang needs to be en.

Having:

.
└── path-to-sync-recursively
    ├── video1
    │   ├── video1.en.srt
    │   └── video1.mkv
    └── video2
        ├── video2.en.srt
        └── video2.mkv

Using the command:

python3 rSubsync.py --lang en --path /path-to-sync-recursively/

Will do this:

.
└── path-to-sync-recursively
    ├── video1
    │   ├── video1.en.srt
    │   ├── video1.en.srt.old
    │   └── video1.mkv
    └── video2
        ├── video2.en.srt
        ├── video2.en.srt.old
        └── video2.mkv

In case there are errors in the process of syncing any subtitle, it will create a .failed file with the stacktrace.

If you don't specify any path it will use the current one ('.') to start syncing.
