|
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!
|
|
|
|
```go
|
|
// 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
