PHP獲取YouTube視頻的1080p的質量或更高

我試過下面的代碼讓YouTube與所有可能的特質，但它只有720爲最高質量甚至視頻支持更高的品質PHP獲取YouTube視頻的1080p的質量或更高

function get_youtube($code) 
{ 
    $data = file_get_contents('http://youtube.com/get_video_info?video_id=' . $code . '&el=vevo&fmt=18&asv=2&hd=1'); 

    parse_str($data , $details); 

    foreach (explode(',' , $details['url_encoded_fmt_stream_map']) AS $quality) { 
     parse_str($quality , $video); 

     echo '<pre>'; 
     print_r($video); 
     echo '</pre>'; 
    } 



} 


get_youtube('kObNpTFPV5c');

這是輸出

您可以查看YouTube影片具有1080p質量或更高

function get_youtube($code) 
{ 
    $data = file_get_contents('http://youtube.com/get_video_info?video_id=' . $code . '&el=vevo&fmt=18&asv=2&hd=1'); 

    parse_str($data , $details); 
    $my_formats_array = explode(',' , $details['adaptive_fmts']); 
    $avail_formats[] = ''; 
    $i = 0; 
    $ipbits = $ip = $itag = $sig = $quality_label = ''; 
    $expire = time(); 

    foreach ($my_formats_array as $format) { 
     parse_str($format); 
     $avail_formats[$i]['itag'] = $itag; 
     $avail_formats[$i]['quality'] = $quality_label; 
     $type = explode(';', $type); 
     $avail_formats[$i]['type'] = $type[0]; 
     $avail_formats[$i]['url'] = urldecode($url) . '&signature=' . $sig; 
     parse_str(urldecode($url)); 
     $avail_formats[$i]['expires'] = date("G:i:s T", $expire); 
     $avail_formats[$i]['ipbits'] = $ipbits; 
     $avail_formats[$i]['ip'] = $ip; 
     $i++; 
    } 
    var_dump($avail_formats); 
} 
get_youtube('kObNpTFPV5c');

難道說「adaptive_fmts」已不存在的get_video_info的輸出？目前無法進行此項工作... – Nicholas

你可以使用一個基於命令行的youtu是下載者，如youtube-dl。默認情況下，它會下載720p視頻，但似乎有一個新功能可以支持1080p下載！在downloading 1080p video with youtube-dl here.

更多信息從PHP中運行命令來看看這疊後：Running shell commands in .php file from command-line

讓我知道如果您需要任何幫助！
