问题描述

在研究我如何从 YouTube 视频中获取直接 URL 之后，问:

代码:gist.github

有什么解决办法吗?非常感谢

解决方案

这是另一个代码，用于从 youtube get_video_info

获取每个视频质量

 $array["playabilityStatus"]["status"]);}别的{$formats = $array["streamingData"]["formats"];for ($a = 0; $a <= (count($formats) - 1); $a++){$数据[] = 数组(网址"=>$array["streamingData"]["formats"][$a]["url"],mimeType" =>$array["streamingData"]["formats"][$a]["mimeType"],质量" =>$array["streamingData"]["formats"][$a]["quality"],质量标签"=>$array["streamingData"]["formats"][$a]["qualityLabel"],宽度" =>$array["streamingData"]["formats"][$a]["width"],高度" =>$array["streamingData"]["formats"][$a]["height"],音频质量"=>$array["streamingData"]["formats"][$a]["audioQuality"],"approxDurationMs" =>$array["streamingData"]["formats"][0]["approxDurationMs"]);}}返回 $data;}函数 Explode_Content($first, $last, $string){$exp =explode($first, $string);$exp =explode($last, $exp[1]);返回 $exp[0];}$videoinfo = YT_V_INFO("6chhghoMGVQ");//$videoinfo=YT_V_INFO("sJsoyuQAepQ");print_r($videoinfo);?>

如果所有者不允许，使用此方法您将无法获取某些视频 ID 数据.这是两个例子:

$videoinfo = YT_V_INFO("6chhghoMGVQ");

输出:

这是所有者不允许的另一个视频 ID.

$videoinfo=YT_V_INFO("sJsoyuQAepQ");

after research to how i get direct URL from YouTube videos like this one asking : How to get direct URL of video from YouTube URL? [closed]

i finally made a simple script to generate a direct URL from YouTube video with php and it works just fine, but not with all videos

it doesn't work with "signature" videos,

this is my code:

if(isset($_GET['url']) && $_GET['url'] != ""){
    parse_str( parse_url( $_GET['url'], PHP_URL_QUERY ), $vars );


    $id=$vars['v'];
    $dt=file_get_contents("https://www.youtube.com/get_video_info?video_id=$id&el=embedded&ps=default&eurl=&gl=US&hl=en");
    //var_dump(explode("&",$dt));
    if (strpos($dt, 'status=fail') !== false) {

        $x=explode("&",$dt);
        $t=array(); $g=array(); $h=array();

        foreach($x as $r){
            $c=explode("=",$r);
            $n=$c[0]; $v=$c[1];
            $y=urldecode($v);
            $t[$n]=$v;
        }

            $x=explode("&",$dt);
            foreach($x as $r){
                $c=explode("=",$r);
                $n=$c[0]; $v=$c[1];
                $h[$n]=urldecode($v);
            }
            $g[]=$h;
            $g[0]['error'] = true;
            $g[0]['instagram'] = "egy.js";
            $g[0]['apiMadeBy'] = 'El-zahaby';
        echo json_encode($g,JSON_PRETTY_PRINT);

    }else{

        $x=explode("&",$dt);
        $t=array(); $g=array(); $h=array();

        foreach($x as $r){
            $c=explode("=",$r);
            $n=$c[0]; $v=$c[1];
            $y=urldecode($v);
            $t[$n]=$v;
        }
        $streams = explode(',',urldecode($t['url_encoded_fmt_stream_map']));
        foreach($streams as $dt){ 
            $x=explode("&",$dt);
            foreach($x as $r){
                $c=explode("=",$r);
                $n=$c[0]; $v=$c[1];
                $h[$n]=urldecode($v);
            }
            $g[]=$h;
        }
        echo json_encode($g,JSON_PRETTY_PRINT);
       // var_dump( $g[1]["quality"],true);
    }
}else{
    @$myObj->error = true;
    $myObj->msg = "there is no youtube link";

    $myObj->madeBy = "El-zahaby";
    $myObj->instagram = "egy.js";
    $myJSON = json_encode($myObj,JSON_PRETTY_PRINT);

    echo $myJSON;

any solution ? thanks a lot

This is another code to get each video qualities from youtube get_video_info

    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

}
function YT_V_INFO($v){
    $url         = "https://www.youtube.com/get_video_info?video_id=$v";
    $html        = urldecode(YT_IN_DX($url));
    $video_links = Explode_Content('playabilityStatus', 'adSafetyReason', $html);
    $json        = str_replace("u0026", "&", $video_links);
    $json        = '{"playabilityStatus' . $json . 'adSafetyReason":{"isEmbed":true}}';
    $array       = json_decode($json, true);
    if (isset($array["playabilityStatus"]["status"]) && $array["playabilityStatus"]["status"] == "UNPLAYABLE") {
        $data = array("error" => $array["playabilityStatus"]["status"]);
    }else{
        $formats = $array["streamingData"]["formats"];
        for ($a = 0; $a <= (count($formats) - 1); $a++){
            $data[] = array(
                "url" => $array["streamingData"]["formats"][$a]["url"],
                "mimeType" => $array["streamingData"]["formats"][$a]["mimeType"],
                "quality" => $array["streamingData"]["formats"][$a]["quality"],
                "qualityLabel" => $array["streamingData"]["formats"][$a]["qualityLabel"],
                "width" => $array["streamingData"]["formats"][$a]["width"],
                "height" => $array["streamingData"]["formats"][$a]["height"],
                "audioQuality" => $array["streamingData"]["formats"][$a]["audioQuality"],
                "approxDurationMs" => $array["streamingData"]["formats"][0]["approxDurationMs"]
            );
        }
    }
    return $data;
}
function Explode_Content($first, $last, $string)
{
    $exp = explode($first, $string);
    $exp = explode($last, $exp[1]);
    return $exp[0];
}
$videoinfo = YT_V_INFO("6chhghoMGVQ");
// $videoinfo=YT_V_INFO("sJsoyuQAepQ");
print_r($videoinfo);

?>

With this method you can't get some videos ID data, if not allowed by owner. this is two examples :

$videoinfo = YT_V_INFO("6chhghoMGVQ");

Output :
