【问题描述】:
我使用 Youtube API 来收集数据,然后我使用 node.js Youtube Downloader。
最后,我在经典 html5 <video> 标签上使用视频。
由于某些原因,有些视频效果很好,有些则不行。
我在服务器部分使用这个包 -> https://www.npmjs.com/package/youtube-dl
if (request.url.search(/.nidza|.dzoni/g) != -1) {
// file.serveFile('bad.html', 402, {}, request, response);
const localVid = request.url.split("?vid=")
console.log("videoID => ", localVid[1])
console.log("Vule bule request.url., ", request.url)
const addressLink = 'http://www.youtube.com/watch?v=' + localVid[1]
const checkvideo = '../dist/videos/vule' + localVid[1] + '.mp4'
try {
if (fs.existsSync(checkvideo)) {
// file exists
console.log("skip...")
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('[video-exist]');
return;
}
} catch(err) {
console.error(err)
}
const myPromise = new Promise((resolve, reject) => {
var test = youtubedl(addressLink, ['--format=18'], { cwd: __dirname })
try{
resolve(test)
} catch(err) {
reject(err)
}
}).then((video) => {
video.on('info', function(info) {
console.log('Download started')
console.log('filename: ' + info._filename)
console.log('size: ' + info.size)
})
const videoName = '../dist/videos/vule' + localVid[1] + '.mp4';
video.pipe(fs.createWriteStream(videoName, {
flag: "w+"
}))
}).catch(function(err) {
reject().than(()=>{
console.log("Error in promise youtubedl => ", err)
})
});
response.writeHead(200, {'Content-Type': 'text/plain'})
response.end(`VuleTube service version 0.3.1 \n
https://maximumroulette.com:3000 `)
}
错误登录服务器端:

任何建议。
【问题讨论】:
-
请添加可播放视频和不可播放视频之间的差异 - 检查浏览器的网址、网络选项卡,如果这些视频可用(嵌入、盗用、删除等)。
-
不播放的视频是不是快速启动?
-
fast start是什么意思? @szatmary -
“moov”框的位置。如果你不知道这意味着什么,请谷歌它。如果您想流式传输 mp4 文件,这是您绝对必须知道的信息。
-
这并不违法。投诉是由 RIAA(美国艺术家唱片业)提出的。如果你不使用 Taylor Swift 或 Micheal Jackson 这样的美国音乐,那么你就不符合他们的抱怨。这也已修复(YT-DL 拒绝下载此类文件)... PS:我不提倡任何下载,但如果您将其保持为友好使用,而不是一些不尊重和过度盗版,那么您可能会没事。
