I was making this site mp3 to webm for a project in discord and I can record on firefox with every device but chromium works only on windows.
When I record an audio it gets stored locally and converts to a black canvas to embed on discord then a bot just ask if the webm is ok or not and if it’s accepted it gets transferred to another channel.
It need to be a embed file because bots on discord.js or py can’t manipulate audios yet
let mediaRecorder;
let audioChunks = [];
let audioBlob;
let canvas;
let canvasStream;
let audioStream;
function createCanvasWithNickname(name) {
canvas = document.createElement('canvas');
canvas.width = 400;
canvas.height = 144;
const ctx = canvas.getContext('2d');
ctx.fillStyle = 'black';
ctx.fillRect(0, 0, 400, 144);
ctx.fillStyle = 'white';
ctx.font = '24px Arial';
ctx.textAlign = 'center';
ctx.textBaseline = 'middle';
ctx.fillText(name, 200, 72);
return canvas.captureStream(30);
}
// Funzione per inizializzare l'audio con un metodo alternativo
async function initializeAudio() {
const stream = await navigator.mediaDevices.getUserMedia({ audio: true });
audioStream = stream;
}
document.getElementById('recordButton').addEventListener('click', async () => {
const name = document.getElementById('nameInput').value.trim();
canvasStream = createCanvasWithNickname(name);
await initializeAudio();
const combinedStream = new MediaStream([...canvasStream.getTracks(), ...audioStream.getTracks()]);
mediaRecorder = new MediaRecorder(combinedStream, { mimeType: 'video/webm' });
mediaRecorder.start();
mediaRecorder.ondataavailable = (event) => {
audioChunks.push(event.data);
};
mediaRecorder.onstop = () => {
audioBlob = new Blob(audioChunks, { type: 'video/webm' });
const audioUrl = URL.createObjectURL(audioBlob);
document.getElementById('audioPreview').src = audioUrl;
document.getElementById('recordButton').disabled = false;
document.getElementById('stopButton').disabled = true;
document.getElementById('sendButton').disabled = false;
};
document.getElementById('recordButton').disabled = true;
document.getElementById('stopButton').disabled = false;
});
document.getElementById('stopButton').addEventListener('click', () => {
mediaRecorder.stop();
});
document.getElementById('sendButton').addEventListener('click', async () => {
const name = document.getElementById('nameInput').value.trim();
if (!name) {
alert('Devi inserire un nickname!');
return;
}
const formData = new FormData();
formData.append('file', audioBlob, 'audio.webm');
formData.append('username', name);
try {
await fetch('webhookhere', {
method: 'POST',
body: formData
});
alert('Audio inviato a Discord con successo!');
} catch (error) {
console.error('Errore durante l'invio del file:', error);
}
});
I tried lots of workaround and did research but all I find are people with the same problem and no answers
