how can i use this code in nodejs
I think it's better to use youtube-dl on NodeJS.
Examples
const { getInfo } = require('ytdl-getinfo')
const youtube_video_id = "XxEhuSJF780"; // you can use full url too, https://www.youtube.com/watch?v=XxEhuSJF780Method 1
getInfo( youtube_video_id ).then(info => {
// info.items[0] should contain the output of youtube-dl --dump-json
console.log( info.items[0] )
});Method 2
getInfo( youtube_video_id, ['--dump-json'] ).then(info => {
console.log( info.items[0] )
});References:
old ytInfoUrl += "www.youtube.com/get_video_info?video_id=" + videoID + "&eurl="
+ URLEncoder.encode("https://youtube.googleapis.com/v/" + videoID, "UTF-8")
+"&html5=1&c=TVHTML5&cver=6.20180913";
and i update new ytInfoUrl
ytInfoUrl += "www.youtube.com/get_video_info?video_id=" + videoID + "&eurl="
+ URLEncoder.encode("https://www.youtube.com/youtubei/v1/player?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8/" + videoID, "UTF-8")
+"&html5=1&c=TVHTML5&cver=6.20180913";
but still video not playing and showing the W/System.err: java.io.FileNotFoundException Error
@surajpendhare @thenandkishorkumawat
Your solution is working for me.
But, How can i parse response in node js.
const request = require('request');
const youtube_video_id = 'XxEhuSJF780'; // https://www.youtube.com/watch?v=XxEhuSJF780
var options = {

},

},

})
};
request(options, function(error, response, body) {
if (error) throw new Error(error);
console.log(JSON.parse(body));
});

How do I return the MP4 URL for download using PHP? My function is below:
`function getVideoInfo($video_id){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.youtube.com/youtubei/v1/player?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
