Subtitles

To show subtitles you have two options:

Use an HLS stream with embedded subtitles.
Use an HLS stream as FPExternalMedia and configure the URL to subtitles.

Using FPExternalMedia with VTT files

If you're using FPExternalMedia, you can configure the subtitles by hand:

Copy

Copied

let track = FPTrack(
        lang: "en",
        src: "https://mycdn.example.com/subs.vtt",
        label: "English subs",
        kind: ""
)

let externalMedia = FPExternalMedia(
        mediaUrl: "https://mycdn.example.com/video.m3u8",
        adSchedule: nil,
        metadata: nil,
        subtitles: [track]
 )

Please note that subtitles only work with HLS streams. This also applies when using FPExternalMedia.
