public Text durationText; // 显示视频时长的UI Text组件
public Text nowText; // 显示视频时长的UI Text组件

}
private void OnMediaPlayerEvent(MediaPlayer player, MediaPlayerEvent.EventType eventType, ErrorCode errorCode)

{
InvokeRepeating("UpdateProgressBar", 0f, 0.1f); // 每0.1秒更新一次进度条
}
}
public void OnVideoSeekSlider1()
{
videoPlayer.Control.Seek(slider.value * videoPlayer.Info.GetDurationMs());
}

void UpdateProgressBar()
{
totalDuration = (float)videoPlayer.Info.GetDurationMs()/1000;

int hours = (int)(totalDuration / 3600);
int minutes = (int)((totalDuration % 3600) / 60);
int seconds = (int)(totalDuration % 60);

durationText.text = string.Format("{1:D1}:{2:D2}", hours, minutes, seconds);

int cut = (int)(videoPlayer.Control.GetCurrentTimeMs()/1000);
int minutes2 = ((cut % 3600) / 60);
int seconds2 = (cut % 60);
nowText.text = string.Format("{1:D1}:{2:D2}", hours, minutes2, seconds2);

if (videoPlayer && videoPlayer.Info != null)
{
time = videoPlayer.Control.GetCurrentTimeMs() ;

if (videoPlayer.Info.GetDurationMs() <= 0)
{
return;
}
double vol = (time / videoPlayer.Info.GetDurationMs());
slider.SetValueWithoutNotify((float)vol);
}
}
