I want to reproduce all youtube files embedded on a site using SoundManager2 audio player. How can I get access to Youtube file URL from video ID?
Note: Soundcloud offers the possibility to get the direct streaming URL from the song URL. Here is a working example with Soundmanager2 and Angular. Now I want to do the same for Youtube.
Your title said using API. It's not possible to get access to YouTube file URL from video ID by that. By mean, with file URL you can also download it, distribute content etc while it's against YouTube Terms. So there is no such API for that.
Since you're tagged with Javascript, there is possibility to get direct access to the file URL. This probably is not as you wanted exactly but it worked flawlessly from the developer tools console available in any browser. For details Here you go
const videoUrls = ytplayer.config.args.url_encoded_fmt_stream_map
.split(',')
.map(item => item
.split('&')
.reduce((prev, curr) => (curr = curr.split('='),
Object.assign(prev, {[curr[0]]: decodeURIComponent(curr[1])})
), {})
)
.reduce((prev, curr) => Object.assign(prev, {
[curr.quality + ':' + curr.type.split(';')[0]]: curr
}), {});
console.log(videoUrls);
One slightly hacky way - You could use Youtube's OEmbed API, however you need to provide a URL, so you'd need to add the ID onto the end.
https://www.youtube.com/oembed?url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DiwGFalTRHDA
This will consistently return an embed iframe, which you could regex the URL out of.
var regex = /<iframe.*?src='(.*?)'/;
var src = regex.exec(str)[1];

I am trying to build a mini browser using Electron.js. Is it possible to make urls like chrome://settings or about:config, so that when the user goes to that link I can show an html file? I basically want to associate a url with a file in electron.
You could use Data URIs, and base64-encode the contents of your data as a link. You can use Javascript to encode and decode binary data, then you just specify the MIME type at the start.
If you go to the following URL in a browser for example you'll see a png decoded and rendered:
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==
The MDN Web doc in the first link mentions the process of base64 encoding an HTML file.
Alternatively, if you just want to force the download of a link you could add the download attribute to your anchor.
You can use did-start-navigation to detect when they go to chrome://settings/ then intercept that and tell it to go to https://stackoverflow.com/ instead.
Here's the code:
mainWin.webContents.on('did-start-navigation', function (evt, navigateUrl) {
if (navigateUrl == 'chrome://settings/') {
evt.preventDefault();
setTimeout(function () { // Without this it just crashes, no idea why.
mainWin.loadURL('https://stackoverflow.com/');
}, 0);
}
});
I tried the `will-navigate` event, but it didn't work.

After a little searching at npm, I found a package that does exactly what I want, it's electron protocols. It's a simple way to add custom protolcs in Electron, Here's an example"
const protocols = require('electron-protocols');
const path = require('path');
protocols.register('browser', uri => {
let base = app.getAppPath();
if(uri.hostname == "newtab"){
return path.join(base,"newtab.html")
}
});
In this example, if you go to the link browser://newtab, it opens newtab.html. And if you type location.href the DevTools it shows browser://newtab there too
I have been trying to build a a media player in react native using Expo to be able to play audio on my music project.
I have successfully hacked one together with the preferred design etc but I still have a minor bug. Here, I receive information from an API Endpoint with Links to files stored in a server. this audios play when the filename is just one word. When there are spaces in the name, the file, it does not play. eg .../musics/test.mp3 plays while .../musics/test 32.mp3 does not play. Any idea on how to handle this issue in React native will be highly appreciated. My play function
startPlay = async (index = this.index, playing = false) => {
const url = this.list[index].url;
this.index = index;
console.log(url);
// Checking if now playing music, if yes stop that
if(playing) {
await this.soundObject.stopAsync();
} else {
// Checking if item already loaded, if yes just play, else load music before play
if(this.soundObject._loaded) {
await this.soundObject.playAsync();
} else {
await this.soundObject.loadAsync(url);
await this.soundObject.playAsync();
}
}
};
url is the link to the file .
I am working on a streaming platform and I will love to get a player similar to this:
Something like this https://hackernoon.com/building-a-music-streaming-app-using-react-native-6d0878a13ba4
But I am using React native expo. All the implementations I have come across online are using native without expo. Any pointers to any already done work on this using expo will be of great help eg packages .
thanks
The urls should be encoded:
const uri = this.list[index].url;
this.index = index;
const url = encodeURI(uri);
console.log(url);
The uri = "../musics/test 32.mp3" will be encoded to url = "../musics/test%2032.mp3"
While trying to determine a solution to How to use Web Speech API at chromium? found that
var voices = window.speechSynthesis.getVoices();
returns an empty array for voices identifier.
Not certain if lack of support at chromium browser is related to this issue Not OK, Google: Chromium voice extension pulled after spying concerns?
Questions:
1) Are there any workarounds which can implement the requirement of creating or converting audio from text at chromium browser?
2) How can we, the developer community, create an open source database of audio files reflecting both common and uncommon words; served with appropriate CORS headers?
There are several possible workarounds that have found which provide the ability to create audio from text; two of which require requesting an external resource, the other uses meSpeak.js by #masswerk.
Using approach described at Download the Audio Pronunciation of Words from Google, which suffers from not being able to pre-determine which words actually exist as a file at the resource without writing a shell script or performing a HEAD request to check if a network error occurs. For example, the word "do" is not available at the resource used below.
window.addEventListener("load", () => {
const textarea = document.querySelector("textarea");
const audio = document.createElement("audio");
const mimecodec = "audio/webm; codecs=opus";
audio.controls = "controls";
document.body.appendChild(audio);
audio.addEventListener("canplay", e => {
audio.play();
});
let words = textarea.value.trim().match(/\w+/g);
const url = "https://ssl.gstatic.com/dictionary/static/sounds/de/0/";
const mediatype = ".mp3";
Promise.all(
words.map(word =>
fetch(`https://query.yahooapis.com/v1/public/yql?q=select * from data.uri where url="${url}${word}${mediatype}"&format=json&callback=`)
.then(response => response.json())
.then(({query: {results: {url}}}) =>
fetch(url).then(response => response.blob())
.then(blob => blob)
)
)
)
.then(blobs => {
// const a = document.createElement("a");
audio.src = URL.createObjectURL(new Blob(blobs, {
type: mimecodec
}));
// a.download = words.join("-") + ".webm";
// a.click()
})
.catch(err => console.log(err));
});

Resources at Wikimedia Commons Category:Public domain are not necessary served from same directory, see How to retrieve Wiktionary word content?, wikionary API - meaning of words.
If the precise location of the resource is known, the audio can be requested, though the URL may include prefixes other than the word itself.
fetch("https://upload.wikimedia.org/wikipedia/commons/c/c5/En-uk-hello-1.ogg")
.then(response => response.blob())
.then(blob => new Audio(URL.createObjectURL(blob)).play());
Not entirely sure how to use the Wikipedia API, How to get Wikipedia content using Wikipedia's API?, Is there a clean wikipedia API just for retrieve content summary? to get only the audio file. The JSON response would need to be parsed for text ending in .ogg, then a second request would need to be made for the resource itself.
fetch("https://en.wiktionary.org/w/api.php?action=parse&format=json&prop=text&callback=?&page=hello")
.then(response => response.text())
.then(data => {
new Audio(location.protocol + data.match(/\/\/upload\.wikimedia\.org\/wikipedia\/commons\/[\d-/]+[\w-]+\.ogg/).pop()).play()
})
// "//upload.wikimedia.org/wikipedia/commons/5/52/En-us-hello.ogg\"
which logs
Fetch API cannot load https://en.wiktionary.org/w/api.php?action=parse&format=json&prop=text&callback=?&page=hello. No 'Access-Control-Allow-Origin' header is present on the requested resource
when not requested from same origin. We would need to try to use YQL again, though not certain how to formulate the query to avoid errors.
The third approach uses a slightly modified version of meSpeak.js to generate the audio without making an external request. The modification was to create a proper callback for .loadConfig() method
fetch("https://gist.githubusercontent.com/guest271314/f48ee0658bc9b948766c67126ba9104c/raw/958dd72d317a6087df6b7297d4fee91173e0844d/mespeak.js")
.then(response => response.text())
.then(text => {
const script = document.createElement("script");
script.textContent = text;
document.body.appendChild(script);
return Promise.all([
new Promise(resolve => {
meSpeak.loadConfig("https://gist.githubusercontent.com/guest271314/8421b50dfa0e5e7e5012da132567776a/raw/501fece4fd1fbb4e73f3f0dc133b64be86dae068/mespeak_config.json", resolve)
}),
new Promise(resolve => {
meSpeak.loadVoice("https://gist.githubusercontent.com/guest271314/fa0650d0e0159ac96b21beaf60766bcc/raw/82414d646a7a7ef11bb04ddffe4091f78ef121d3/en.json", resolve)
})
])
})
.then(() => {
// takes approximately 14 seconds to get here
console.log(meSpeak.isConfigLoaded());
meSpeak.speak("what it do my ninja", {
amplitude: 100,
pitch: 5,
speed: 150,
wordgap: 1,
variant: "m7"
});
})
.catch(err => console.log(err));
one caveat of the above approach being that it takes approximately 14 and a half seconds for the three files to load before the audio is played back. However, avoids external requests.
It would be a positive to either or both 1) create a FOSS, developer maintained database or directory of sounds for both common and uncommon words; 2) perform further development of meSpeak.js to reduce load time of the three necessary files; and use Promise based approaches to provide notifications of the progress of of the loading of the files and readiness of the application.
In this users' estimation, it would be a useful resource if developers themselves created and contributed to an online database of files which responded with an audio file of the specific word. Not entirely sure if github is the appropriate venue to host audio files? Will have to consider the possible options if interest in such a project is shown.
I'm going to play YouTube and Vimeo videos using React-Native.
For now I implemented React-Native-Video and it does not support to play YouTube or Vimeo urls while can play direct video urls.
So I just want to get a direct reference to a file (or a stream?) from YouTube Video URL.
e.g from
https://www.youtube.com/watch?v=PCwL3-hkKrg
Is there any good third party services or websites to solve this problem?
No matter what types of code or ways you will use though I'm using React-Native to play YouTube videos currently.
Finally, I was able to get youtube video file reference url from KeepVid website.
Because I don't think the website supports restful api, I fetched its html content and parsed to get download urls.
I didn't write code here as it is very simple.
I would be glad if it helped you.
You can obtain video urls of YouTube by this code:
// ES6 version
const videoUrls = ytplayer.config.args.adaptive_fmts
.split(',')
.map(item => item
.split('&')
.reduce((prev, curr) => (curr = curr.split('='),
Object.assign(prev, {[curr[0]]: decodeURIComponent(curr[1])})
), {})
)
.reduce((prev, curr) => Object.assign(prev, {
[curr.quality_label || curr.type]: curr
}), {});
console.log(videoUrls);
// ES5 version
var videoUrls = ytplayer.config.args.adaptive_fmts
.split(',')
.map(function (item) {
return item
.split('&')
.reduce(function (prev, curr) {
curr = curr.split('=');
return Object.assign(prev, {[curr[0]]: decodeURIComponent(curr[1])})
}, {});
})
.reduce(function (prev, curr) {
return Object.assign(prev, {
[curr.quality_label || curr.type]: curr
});
}, {});
console.log(videoUrls);
I can understand what you want - downloading or playing a video[stream] from URL of Youtube or Vimeo.
The only possible way is to use WebView since it's not possible to get the link to the regarding file (not "direct url") of Vimeo nor YouTube for playing (maybe possible for downloading).
If you have to compose customized control, e.g. with your own SeekBar or buttons, ... then you can implement it by combining with WebView control, right?
I don't expect this will be much trouble to implement.
how to get youtube video id via javascript can anyone help me
here is the youtube http://www.youtube.com/watch?v=mG6DRzIyhOo
For your simple case; use the = javascript String.substr function :
var url = "http://www.youtube.com/watch?v=mG6DRzIyhOo";
var video_id = url.substr(url.indexOf("=")+1);
But since youtube can have a variety of different video url formats, I would recommend using the following solution using regular expressions :
