usePlayerTracks

usePlayerTracks() exposes the current audio and subtitle track selection for the current scoped player.

This hook requires a VideoPlayer scope and a scope-aware media element. The Lit <Video> wrapper does not automatically participate in the scope.

Signature

const tracks = usePlayerTracks();

It returns:

audioTrack
availableAudioTracks
subtitleTrack
availableSubtitleTracks
setAudioTrack(trackIndex)
setSubtitleTrack(trackIndex)

Example

import {VideoPlayer, usePlayerTracks} from "@rixl/media-react";

function CustomTrackControls() {
  const {audioTrack, availableAudioTracks, subtitleTrack, availableSubtitleTracks, setAudioTrack, setSubtitleTrack} = usePlayerTracks();

  return (
    <div className="space-y-2">
      <label>
        Audio
        <select value={audioTrack} onChange={(event) => setAudioTrack(Number(event.target.value))}>
          {availableAudioTracks.map((track) => (
            <option key={track.index} value={track.index}>
              {track.label}
            </option>
          ))}
        </select>
      </label>

      <button type="button" onClick={() => setSubtitleTrack(subtitleTrack === -1 ? 0 : -1)}>
        {subtitleTrack === -1 ? "Turn captions on" : "Turn captions off"}
      </button>

      <div>{`Subtitle options: ${availableSubtitleTracks.length}`}</div>
    </div>
  );
}

function CustomPlayer() {
  return (
    <VideoPlayer>
      <CustomTrackControls />
      {/* scope-aware media element */}
    </VideoPlayer>
  );
}

Notes

Track arrays can be empty until the stream metadata is ready.
subtitleTrack === -1 means subtitles are off.
This hook is intentionally limited to track selection. Global caption styling and caption preference state are outside this API.
