This is a Golang library to manipulate subtitles.

It allows you to manipulate srt, stl, ttml, ssa/ass and webvtt files for now.

Available operations are parsing, writing, syncing, fragmenting, unfragmenting, merging and optimizing.

Installation

To install the library and command line program, use the following:

go get -u github.com/asticode/go-astisub/...

Using the library in your code

WARNING: the code below doesn't handle errors for readibility purposes. However you SHOULD!

// Open subtitles
s1, _ := astisub.OpenFile("/path/to/example.ttml")
s2, _ := astisub.ReadFromSRT(bytes.NewReader([]byte("00:01:00.000 --> 00:02:00.000\nCredits")))

// Add a duration to every subtitles (syncing)
s1.Add(-2*time.Second)

// Fragment the subtitles
s1.Fragment(2*time.Second)

// Merge subtitles
s1.Merge(s2)

// Optimize subtitles
s1.Optimize()

// Unfragment the subtitles
s1.Unfragment()

// Write subtitles
s1.Write("/path/to/example.srt")
var buf = &bytes.Buffer{}
s2.WriteToTTML(buf)

Using the CLI

If astisub has been installed properly you can:

  • convert any type of subtitle to any other type of subtitle:

      astisub convert -i example.srt -o example.ttml
    
  • fragment any type of subtitle:

      astisub fragment -i example.srt -f 2s -o example.out.srt
    
  • merge any type of subtitle into any other type of subtitle:

      astisub merge -i example.srt -i example.ttml -o example.out.srt
    
  • optimize any type of subtitle:

      astisub optimize -i example.srt -o example.out.srt
    
  • unfragment any type of subtitle:

      astisub unfragment -i example.srt -o example.out.srt
    
  • sync any type of subtitle:

      astisub sync -i example.srt -s "-2s" -o example.out.srt
