如何让libvlc_media_player_get_time（）返回更准确的结果？

Question

使用libvlc，如何让libvlc_media_player_get_time（）返回更准确的结果？使用60fps视频时，它返回的值最多只能每秒更新几次。有没有办法让帧精确计时？

Answer 1

这issue表示没有办法从libvlc获得更准确的结果。

但你可以插入它：

private long lastPlayTime = 0;
private long lastPlayTimeGlobal = 0;

 /**
 * Get current play time (interpolated)
 * @see https://github.com/caprica/vlcj/issues/74
 * @return
 */
public float getCurrentTime(){
    long currentTime = directMediaPlayer.getTime();

    if (lastPlayTime == currentTime && lastPlayTime != 0){
        currentTime += System.currentTimeMillis() - lastPlayTimeGlobal;
    } else {
        lastPlayTime = currentTime;
        lastPlayTimeGlobal = System.currentTimeMillis();
    }

    return currentTime * 0.001f;    //to float
}
