Example Modification:

Suppose you want to add support for displaying thumbnails for scene markers in the scrubber. You can modify the ScenePlayerScrubber component to include thumbnails for each scene marker. Additionally, you can enhance the marker rendering logic to handle thumbnail display based on specific conditions.

// Example modification code for ScenePlayerScrubber component
// Add thumbnail display for scene markers
const ScenePlayerScrubber: React.FC<IScenePlayerScrubberProps> = ({
  file,
  scene,
  time,
  onSeek,
  onScroll,
}) => {
  return (
    <div className="scene-player-scrubber">
      {scene.scene_markers.map((marker) => (
        <div
          key={marker.seconds}
          className="scene-marker"
          style={{ left: `${(marker.seconds / file.duration) * 100}%` }}
        >
          <img src={marker.thumbnailUrl} alt="Marker Thumbnail" />
          <div className="marker-label">{marker.title}</div>
        </div>
      ))}
    </div>
  );
};

Explanation:

With this modification, the ScenePlayerScrubber component will display thumbnails along with titles for each scene marker in the scrubber. The modification enhances the user experience by providing visual cues for scene transitions and important points in the video content.
