  Getting Error during conversion on this server. I tried running it on replit but giving the error all the time. I'm new to this and can't figure out the issue. CHATGPT-4 couldn't help.
Can someone help me with this ???

  


  ChatGPT said - The "Error during conversion : Input stream error : Status code : 410" indicates a "Gone" error, which means the resource you were trying to access is no longer available at the specified URL. This can occur in situations where YouTube content has been removed or is no longer accessible due to changes in YouTube's policy or the specific video's availability.

  


• how to prevent the hls video player dont refresh when m3u8 changes

  6 juin 2024, par Leo

  here i am using ffmpeg to use camera and audio to make a hls stream on server as the stream continious old m3u8 components deletes and new ones gets added to main.m3u8. but as we insert the url of hls stream file main.m3u8. the player refreshes as soon as the file gets rewritten because of new and old ones. so

  


  i have tried to change the players like hls.js or videojs etc none were to solve this. how to solve this and make sure the stream runs smoothly.

  


  Server.js

  


  const startStreaming = (viddev,auddev) => {
    if (ffmpegProcess) {
        ffmpegProcess.kill();
    }
    const segmentDuration = 10;
    const outputFilename = './video/output.m3u8';
    const ffmpegCommand = `ffmpeg -f dshow -i video="${viddev}" -f dshow -i audio="${auddev}" -codec:v libx264 -preset ultrafast -tune zerolatency -codec:a aac -b:a 128k -hls_time ${segmentDuration} -hls_list_size 3 -hls_flags delete_segments -start_number 0 -hls_segment_type mpegts ${outputFilename}`;

    ffmpegProcess = exec(ffmpegCommand);

    ffmpegProcess.stderr.on('data', (data) => {
        console.error(`ffmpeg stderr: ${data}`);
    });

    ffmpegProcess.on('close', (code) => {
        console.log(`ffmpeg process exited with code ${code}`);
    });
};

app.use('/video', express.static(path.join(__dirname, 'video')));

// Endpoint to list audio and video devices
app.get('/devices', async (req, res) => {
    const data=await parseDevices()
    // console.log(data.cameras[0].name)
    startStreaming(data.cameras[0].name,data.microphones[0].name);
    res.json(data)
});

• How to Extract Frames from the uploaded video through ffmpeg using node js ?

  2 février 2021, par Aditya Vyas

  I have created application in which user uploads a video , from that video i want to extract 50 images using ffmpeg in nodejs, but i am unable to get that file after uploading it in specific folder. I am uploading video through multer as it stores video in specified folder, after that i read that video using read stream but it is not giving proper information on that particular video

  


  Code :

  


  var express = require('express');

var app = express();

var bodyParser = require('body-parser');

var path = require('path');

var multer = require('multer');

var cfenv = require('cfenv');

var watson = require('watson-developer-cloud');

var ffmpeg = require('ffmpeg');

app.use(bodyParser.json());

app.use(bodyParser.urlencoded({"extended": false}));

app.use(express.static(__dirname + '/public'));

var storage = multer.diskStorage({
    destination: function(req, file, callback){
        callback(null, './public/class'); // set the destination
    },
    filename: function(req, file, callback){
        callback(null, 199212+ '.avi'); // set the file name and extension
    }
});

var upload = multer({storage: storage});
 
 app.upload = upload;
 
 // get the app environment from Cloud Foundry
 var appEnv = cfenv.getAppEnv();

var VisualRecognitionV3 = require('watson-developer-cloud/visual-recognition/v3');

var fs = require('fs');


var visualRecognition = new VisualRecognitionV3({
  version: '2018-03-19',
  iam_apikey: 'aaIFu-fHWBXgj09eVarEQUFlIaTeH9bpgvRqHIJxu_8N'
});


app.post('/imgtable',app.upload.single('video-upl'),function(req,res){
                
    var video_file = fs.createReadStream(req.file.path);
                                    
 try {
    var process = new ffmpeg('./public/class/199212.avi');
    process.then(function (video) {
        // Video metadata
        console.log('******************************');
        console.log(video);
        // FFmpeg configuration
        console.log('*********************************');
        console.log(video.info_configuration);
    }, function (err) {
        console.log('Error: ' + err);
    });
} catch (e) {
    console.log(e.code);
    console.log(e.msg);
}

    
})

app.listen(3000);`
