This repository contains a  plugin package for [yt-dlp](https://github.com/yt-dlp/yt-dlp#readme). 
It fixes duplicate lines in YouTube subtitles and saves a additonal srt file called filename.fixed.srt

## Installation

Requires yt-dlp `2023.01.02` or above.

save srt_fix.py under
`C:\Users\{username}\AppData\Roaming\yt-dlp\plugins\srt_fix\yt_dlp_plugins\postprocessor`

When using yt-dlp.exe , create a folder `yt-dlp-plugins` in the same folder as your .exe file. Then place the extracted srt_fix folder inside the `yt-dlp-plugins` folder. like this:

`"some_folder\yt-dlp.exe"`

`"some_folder\yt-dlp-plugins\srt_fix\yt_dlp_plugins\postprocessor\srt_fix.py"`

You can install this package with pip:
```
python3 -m pip install -U https://github.com/bindestriche/srt_fix/master.zip
```
or
```
python3 -m pip install -U https://github.com/bindestriche/srt_fix/archive/refs/heads/master.zip
```

See [installing yt-dlp plugins](https://github.com/yt-dlp/yt-dlp#installing-plugins) for the other methods this plugin package can be installed.

## usage

` yt-dlp https://www.youtube.com/xxxx --write-auto-sub  --sub-lang en  --convert-subs=srt  --use-postprocessor srt_fix`

### known issues

#### --skip-downlaod
If you use the `--skip download` argument in yt-dlp the postprocessor is not triggered and no conversion happens.
you can use `--use-postprocessor srt_fix:when=before_dl` to trigger the ppstprocessor before the download

`yt-dlp.exe https://www.youtube.com/watch?v=xxxx  --write-sub    --use-postprocessor srt_fix:when=before_dl --all-subs --skip-download`

#### --embed-subtitles
embedding of subtitles is not supported. Please use another tool to add them yourself. You allready have ffmpeg so you could run:

for one language:
`ffmpeg -i input.mp4 -i ger.srt -c copy -c:s mov_text -strict -2 -metadata:s:s:0 language=ger output-ger.mp4`
replace the language string with the   [ISO 639-2/B language code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) for your subtitles.

for several languages at once you need to use map:
`ffmpeg -i input.mp4 -i input1.srt -i input2.srt -strict -2 -c copy -c:s mov_text -map 0 -map 1 -metadata:s:s:0 language=lang1 -map 2 -metadata:s:s:1 language=lang2 output.mp4`

SRT Fixer is a simple Python-based tool that processes and fixes issues with SRT subtitle files. The tool removes duplicate lines and corrects timing issues in SRT files, which are common problems in YouTube's automatically generated subtitles. The application is built using Python's Tkinter library for an easy-to-use graphical user interface.

* Fix duplicate lines in subtitle files
* Correct overlapping timings
* Process single files or an entire folder of SRT files

## Installation

Download the .exe from https://github.com/bindestriche/srt_fix/releases , which you should also find on the right hand of  this page

and run
'python srt_fixer_gui.py'

## Usage

Select an output folder to save the fixed SRT files.
Click the "Fix Subtitles" button to process and fix the selected subtitle files.
A progress bar will show the progress of the subtitle processing.
Upon completion, a success message will be displayed, and the output folder will open in File Explorer.
