A dead simple vtt parser in Elixir.

Usage

Decoding

Vtt has two basic ways to use it.

String Parsing

iex> vtt = """
           WEBVTT

           1
           00:00:15.450 --> 00:00:17.609
           Hello world!
           """
...> Vtt.parse(vtt)
%Vtt{cues: [%Vtt.Cue{end: 17609, part: 1, start: 15450, text: "Hello world!", voice: nil}]}

Simple Voice Spans

(Closing voice spans are currently not supported)

iex> vtt = """
           WEBVTT

           1
           00:00:15.450 --> 00:00:17.609
           <v Andy>Hello world!
           """
...> Vtt.parse(vtt)
%Vtt{cues: [%Vtt.Cue{end: 17609, part: 1, start: 15450, text: "Hello world!", voice: "Andy"}]}

Encoding

Vtt also supports encoding parts.

iex> vtt = %Vtt{cues: [%Vtt.Cue{end: 17609, part: 1, start: 15450, text: "Hello world!"}]}
...> Vtt.encode(vtt)
"""
WEBVTT
1
00:00:15.450 --> 00:00:17.609
Hello world!
"""

iex> vtt = %Vtt{cues: [%Vtt.Cue{end: 17609, part: 1, start: 15450, text: "Hello world!", voice: "Andy"}]}
...> Vtt.encode(vtt)
"""
WEBVTT
1
00:00:15.450 --> 00:00:17.609
<v Andy>Hello world!
"""
