 #### 재생 진행률 추적
+- `progressInterval`이 설정된 경우, 해당 간격(ms)마다 `onProgress` 콜백이 호출됩니다.
+- `progressInterval`이 `undefined`이거나 `0` 또는 `null`인 경우, `onProgress` 콜백은 호출되지 않습니다.

 #### Playback Progress Tracking
+- If `progressInterval` is provided, the `onProgress` callback will be invoked at the specified interval (in milliseconds).
+- If `progressInterval` is `undefined`, `0`, or `null`, progress tracking is disabled and `onProgress` will not be called.
