VobSub2SRT is a simple command line program to convert .idx / .sub subtitles into .srt text subtitles by using OCR. It is based on code from the MPlayer project - a really really great movie player. Some minor parts are copied from ffmpeg/avutil headers. Tesseract is used as OCR software.
An example of using the tool is below, note that you can pass a --blacklist of characters to help the OCR recognition - there is also a sub-command vobsub2srt.with-basic-blacklist which has a basic blacklist. If you want to see the processing of each line you can pass --verbose.
If you have the files subtitles.idx subtitles.sub simply run the command vobsub2srt subtitles this will generate a new file called subtitles.srt.
This is an unofficial snap and is not necessarily endorsed or officially maintained by the upstream developers.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install vobsub2srt, simply use the following command:
sudo snap install vobsub2srt
Browse and find snaps from the convenience of your desktop using the snap store snap.
