vobsub2srt (convert VOBSUB subtitles to SRT) 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. Some minor parts are copied from ffmpeg/avutil headers. Tesseract is used as OCR software. vobsub2srt is released under the GPL3+ license. The MPlayer code included is GPL2+ licensed. The quality of the OCR depends on the text in the subtitles. Currently the code does not use any preprocessing. But you can correct mistakes in the =.srt= files with a text editor or a special subtitle editor.
