我来自孟加拉国。我有一个youtube下载PHP脚本，但它不工作一些视频下载。当我点击下载按钮，它下载视频播放并向我显示文本失败 - 禁止。
我无法下载与以下视频相同的内容。大部分视频未下载。
下载网站是：http://mcv12.masudtools.xyz/
如此视频：
我也有错误日志：

尝试此选项仅从youtube视频ID
获取Youtube视频源 // Get Youtube Source
function getYoutubeVideoSource1($id = 'jNQXAC9IVRw'){
parse_str(file_get_contents("http://youtube.com/get_video_info?video_id=".$id),$info);
$streams = $info['url_encoded_fmt_stream_map'];
$streams = explode(',',$streams);
//dd($streams);
// store value in array
$video_stream = array();
foreach ($streams as $stream){
parse_str($stream,$data);
$data = array(
'type' => $data['type'],
'quality' => $data['quality'],
'url' => $data['url'],
);
$video_stream[] = (object) $data;
}
print_r($video_stream);
//return $video_stream;
}
在这里，您将获得一系列视频流。
array:4 [▼
0 => {#216 ▼
+"type": "video/webm; codecs="vp8.0, vorbis""
+"quality": "medium"
+"url": "https://r3---sn-ugp5obax-q5je.googlevideo.com/videoplayback?ipbits=0&ei=qC_9Wa3HD9rcogOXgZuAAw&lmt=1380226535526270&expire=1509786632&sparams=clen%2Cdur%2Cei%2C ▶"
}
1 => {#211 ▶}
2 => {#212 ▶}
3 => {#218 ▶}
]
现在你可以获得像这样的视频链接
// Get Youtube Batch Download link
function youtubeBatchDownloadLink($videoId, $format){
$video_source = getYoutubeVideoSource ($videoId);
$url = $video_source[$format]->url;
print_r($url);
//return $url;
}
希望这会对你有所帮助

由于最新的回复与youtube的当前结果不合时宜，因此我想发布更新。对于使用上述代码的任何人，url_encoded_fmt_stream_map都会引发错误，因为YouTube将该参数的值更改为player_response。
下面的代码将输出一个包含YouTube视频源URL的JSON对象。
<?php

header('Access-Control-Allow-Origin: *');
header('Content-Type: application/json');
function get_error($ErrorExaction){
$myObj = new stdClass();
$myObj->error = true;
$myObj->msg = $ErrorExaction;
$myJSON = json_encode($myObj,JSON_PRETTY_PRINT);
echo $myJSON;
exit;
}
// pass youtube url via param
if(isset($_GET['ytURL']) && $_GET['ytURL'] != "") {
// parse the url param to split the string
parse_str( parse_url( $_GET['ytURL'], PHP_URL_QUERY ), $vars );
$id = $vars['v']; // get the video id from the v query param
$dt = file_get_contents("https://www.youtube.com/get_video_info?video_id=$id&el=embedded&ps=default&eurl=&gl=US&hl=en");
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;
$g[0]['error'] = true;
echo json_encode($g,JSON_PRETTY_PRINT);
} else {
// decode the response
$x=explode("&",$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;
}
// get the "player_response" field and parse it as JSON
$player_response = json_decode(urldecode($t['player_response']), true);
// if response is missing streaming data - show an error and exit
if(!array_key_exists("streamingData",$player_response)){
get_error('ops! this video has something wrong! :( ');
}
// get reference to the streaming data object
$streams = $player_response["streamingData"];
// loop through the list and print out all formats
echo "{ \"formats\": [";
foreach ($streams["formats"] as $formats) {
echo "{ \"". $formats["qualityLabel"] ."\": \"". $formats["url"] ."\" },";
}
echo "], \"adaptiveFormats\": [";
foreach ($streams["adaptiveFormats"] as $adaptiveFormats) {
if(array_key_exists("qualityLabel",$adaptiveFormats)){
echo "{ \"". $adaptiveFormats["qualityLabel"] ."\": \"". $adaptiveFormats["url"] ."\" },";
} else {
break; // end the loop
}
}
echo "]}";
}
} else {
get_error("Ops, there is no youtube link!");
}
使用以下命令调用此脚本：
/YouTubeSourcer.php?ytURL=https://www.youtube.com/watch?v=nMAzchVWTis
