• How to stream to the stream name come in response from Youtube livestream api

  7 décembre 2018, par Anirudha Gupta

  I am calling this API https://developers.google.com/youtube/v3/live/docs/liveStreams/insert ? to get stream name from Livestream API

  {
  
   "kind": "youtube#liveStream",
  
   "etag": "\"etag"",
  
   "id": "-ABa1o",
  
   "snippet": {
  
    "publishedAt": "2018-12-07T05:41:12.000Z",
  
    "channelId": "UC-
  
    "title": "Hello World",
  
    "description": "Snippet description of testing",
  
    "isDefaultStream": false
  
   },
  
   "cdn": {
  
    "format": "360p",
  
    "ingestionType": "rtmp",
  
    "ingestionInfo": {
  
     "streamName": "9qq0-ct85-ctub-",
  
     "ingestionAddress": "rtmp://a.rtmp.youtube.com/live2",
  
     "backupIngestionAddress": "rtmp://b.rtmp.youtube.com/live2?backup=1"
  
    },
  
    "resolution": "360p",
  
    "frameRate": "30fps"
  
   },
  
   "status": {
  
    "streamStatus": "ready",
  
    "healthStatus": {
  
     "status": "noData"
  
    }
  
   },
  
   "contentDetails": {
  
    "closedCaptionsIngestionUrl": "http://upload.youtube.com/closedcaption?cid=9qq0-ct85-ctub-",
  
    "isReusable": true
  
   }
  
  }

  I see a response like this, When I use OBS to stream to this RMTP URL it doesn’t have the title I set in the stream as you can see come in response. I am getting stream name but not sure if I do it correctly.

  If I call the path as rtmp://a.rtmp.youtube.com/live2/steamnamefromurl/mykey
  it’s work but not have the title I set by call API. Anyone please check the page and help what I am going wrong. What I am looking for is get the title and description set for stream, or verified that I am doing it correctly.

• ffmpeg youtube livestream not working

  21 avril 2017, par Select

  Today i tried using ffmpeg on my debian 8.3 server to livestream 24/7 hours. However it doesnt work.

  #! /bin/bash
  
  
  
  INRES="1280x1024" # input resolution (The resolution of the program you want to stream!)
  
  OUTRES="1024x790" # Output resolution (The resolution you want your stream to be at)
  
  FPS="60" # target FPS
  
  QUAL="ultrafast" 
  
  # one of the many FFMPEG presets that can be used 
  
  # If you have low bandwidth, put the qual preset on 'ultrafast' (upload bandwidth)
  
  # If you have medium bandwitch put it on normal to medium or fast
  
  STREAM_KEY="hidden" # this is your streamkey
  
  
  
  
  
  
  
  
  
  ffmpeg -f "file.avi" -s "$INRES" -r "$FPS" -i :0.0 \
  
  -f alsa -ac 2 -i pulse -vcodec libx264 -s "$OUTRES" \
  
  -acodec libmp3lame -ab 128k -ar 44100 -threads 0 \
  
  -f flv "rtmp://a.rtmp.youtube.com/live2" 

  it gives me the output

  Unknown input format : ’file.avi’

• Firebase function to convert YouTube to mp3

  9 octobre 2023, par satchel

  I want to deploy to Firebase cloud functions.

  


  However, I get a vague error : “Cannot analyze code” after it goes through the initial pre deploy checks successfully.

  


  But I cannot figure out the problem given the vagueness of the error.

  


  It looks right with these requirements :

  


  

  • receive a POST with JSON body of YouTube videoID as a string

  


  • Download locally using the YouTube download package

  


  • Pipe to the ffmpeg package and save mp3 to the local temp

  


  • Store in default bucket on firestore storage

  


  • Apply make public method to make public

  


  


  const functions = require('firebase-functions');
const admin = require('firebase-admin');
const ytdl = require('ytdl-core');
const ffmpeg = require('fluent-ffmpeg');
const fs = require('fs');
const path = require('path');
const os = require('os');

admin.initializeApp();

// Set the path to the FFmpeg binary
const ffmpegPath = path.join(__dirname, 'bin', 'ffmpeg');
ffmpeg.setFfmpegPath(ffmpegPath);

exports.audioUrl = functions.https.onRequest(async (req, res) => {
    if (req.method !== 'POST') {
        res.status(405).send('Method Not Allowed');
        return;
    }

    const videoId = req.body.videoID;
    const videoUrl = `https://www.youtube.com/watch?v=${videoId}`;
    const audioPath = path.join(os.tmpdir(), `${videoId}.mp3`);

    try {
        await new Promise((resolve, reject) => {
            ytdl(videoUrl, { filter: format => format.container === 'mp4' })
                .pipe(ffmpeg())
                .audioCodec('libmp3lame')
                .save(audioPath)
                .on('end', resolve)
                .on('error', reject);
        });

        const bucket = admin.storage().bucket();
        const file = bucket.file(`${videoId}.mp3`);
        await bucket.upload(audioPath, {
            destination: file.name,
            metadata: {
                contentType: 'audio/mp3',
            },
        });

        // Make the file publicly accessible
        await file.makePublic();

        const publicUrl = file.publicUrl();
        res.status(200).send({ url: publicUrl });
    } catch (error) {
        console.error('Error processing video:', error);
        res.status(500).send('Internal Server Error');
    }
});


  


  The following is the package.json file which is used to reference the dependencies for the function, as well as the entry point, which I believe just needs to be the name of the filename with the code :

  


  {
  "name": "firebase-functions",
  "description": "Firebase Cloud Functions",
  "main": "audioUrl.js", 
  "dependencies": {
    "firebase-admin": "^10.0.0",
    "firebase-functions": "^4.0.0",
    "ytdl-core": "^4.9.1",
    "fluent-ffmpeg": "^2.1.2"
  },
  "engines": {
    "node": "18"
  },
  "private": true
}


  


  (Edit) Here is the error :

  I get the same error when running the following :

  


  firebase deploy --only functions:audioUrl


  


  And I thought I might get more detailed errors using the emulator :

  


  firebase emulators:start


  


  Under the emulator I had this additional error initially :

  


  Your requested "node" version "18" doesn't match your global version "16". Using node@16 from host.
