This is a Golang library to manipulate subtitles.
It allows you to manipulate `srt`, `stl`, `ttml`, `ssa/ass`, `webvtt` and `teletext` files for now.
Available operations are `parsing`, `writing`, `applying linear correction`, `syncing`, `fragmenting`, `unfragmenting`, `merging` and `optimizing`.
# Installation
To install the library:
go get github.com/asticode/go-astisub
To install the CLI:
go install github.com/asticode/go-astisub/astisub
# Using the library in your code
WARNING: the code below doesn't handle errors for readibility purposes. However you SHOULD!
```go
// Open subtitles
s1, _ := astisub.OpenFile("/path/to/example.ttml")
s2, _ := astisub.ReadFromSRT(bytes.NewReader([]byte("1\n00:01:00.000 --> 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()
// Apply linear correction
s1.ApplyLinearCorrection(1*time.Second, 2*time.Second, 5*time.Second, 7*time.Second)
// 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
- apply linear correction to any type of subtitle:
astisub apply-linear-correction -i example.srt -a1 1s -d1 2s -a2 5s -d2 7s -o example.out.srt
- 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
