嗨，朋友们，我想开发一个倒带功能，当我点击倒带按钮时，YouTube视频显示在I帧倒带10秒，但我不能得到我怎么能创建这个，如果你有任何解决方案，请尽快与我分享。
这是我的代码。

<?php
$val="";
$vid="0TvTyj5FAaQ";
$str = file_get_contents('video.json');
$json = json_decode($str, true);
foreach ($json as $value) {
if($value'["id"']==$vid){
$val="TRUE";
break;
}else{
continue;
}
}
if($val=="TRUE"){ ?>
<div>
<div style="height: 345px;width: 700px;background: black;">
<span style="color: white;">This video has restricted content.</span>
</div>
</div>
<?php }else{

<div id="player">
<iframe id="player" width="700" height="345" src="https://www.youtube.com/embed/<?php echo $vid?>?enablejsapi=1&showinfo=0&rel=0"> </iframe>
<br/>
<button id='rwnd' onclick="rewind()" >Rewind</button>
</div>
<?php } ?>
<script type="text/javascript">
var player=document.getElementById("player");
var rewind= function(){
if (! player){alert("no obj");
}else{
alert('hello');
var currentTime = player.getCurrentTime();
console.log(currentTime);
if(currentTime>5){
player.seekTo(currentTime - 5, true);
player.playVideo();
}
}
};
</script>
</body>

这是视频。json文件。
[
{
"id": "0dV1Bwe2v6c"
},
{
"id":"0dmhKtQ74wo"
},
{
"id":"0dV1Bwe2v6c"
}
]
朋友们，我现在得到了答案，希望对你们也有帮助。Json文件与我在代码中添加的问题相同。
解决方案如下....
