Please ask your question I am using the live stream below. After meeting the 4-second buffer, playback is starting at a point where the remaining buffer is 3 seconds. But it always starts playing from the 6th video chunk. This appears to play the last 6th video chunk of the last downloaded playlist.

Is it possible to play directly from the 3rd video chunk?

await player.load(url);
this.videoElement.pause(); 
await this.ensurePlaybackBuffer(4);
this.videoElement.play();

async ensurePlaybackBuffer(minBufferLength) {
return new Promise((resolve) => {
	const checkBuffer = () => {
		const buffered = this.videoElement.buffered;
		if (buffered.length > 0) {
			const bufferEnd = buffered.end(buffered.length - 1);
			const currentTime = this.videoElement.currentTime;
			const bufferedAmount = bufferEnd - currentTime;

			if (bufferedAmount >= minBufferLength) {
				const targetTime = currentTime + 3;
				if (bufferEnd > targetTime) {
					this.videoElement.currentTime = targetTime;
				} else {
				}
				resolve();
			} else {
				setTimeout(checkBuffer, 100);
			}
		} else {
			setTimeout(checkBuffer, 100);
		}
	};
	checkBuffer();
});
}

export function getDefaultConfig() {
	return {
		abr: { enabled: false },
		streaming: {
			bufferingGoal: 30,
			rebufferingGoal: 5,
			lowLatencyMode: true,
			startAtSegmentBoundary: true,
			liveSyncMaxLatency: 2,
			updateIntervalSeconds: 0.5,
			retryParameters: { baseDelay: 1000, timeout: 5000, maxAttempts: 2 },
		},
		manifest: {
			hls: {
				liveSegmentsDelay: 1,
			},
			retryParameters: { baseDelay: 1000, timeout: 5000, maxAttempts: 2 },
		},
	};
}
