Seek Video Frame Error

[mtsee]

const videoDecoderConfig = await demuxer.getDecoderConfig('video');

const decoder = new VideoDecoder({
  output: frame => {
    console.log('format', frame);
    ctx.clearRect(0, 0, canvas.width, canvas.height);
    const scale = Math.min(canvas.width / frame.displayWidth, canvas.height / frame.displayHeight);
    ctx.drawImage(frame, 0, 0, frame.displayWidth * scale, frame.displayHeight * scale);
    frame.close();
  },
  error: e => {
    console.error('video decoder error:', e);
  },
});
decoder.configure(videoDecoderConfig);

const videoEncodedChunk = await demuxer.seek('video', 1);
decoder.decode(videoEncodedChunk);
decoder.flush();

上面的代码绘制的画面是黑色的，官方提供的Seek Video Frame 案例也是一样的
