Can someone help me use fetch to transcode and return a response object that is a stream?

[ralyodio]

async start(url, user = null, pass = null) {
			console.log('Transcoding:', url);
			const headers = {};

			try {
				if (user && pass) {
					const encodedCredentials = Buffer.from(`${user}:${pass}`).toString('base64');
					headers['Authorization'] = `Basic ${encodedCredentials}`;
				}

				// Fetch the video from the URL
				const response = await fetch(url, { headers, redirect: 'follow' });

				if (!response.ok) {
					throw new Error(`Failed to fetch video: ${response.statusText}`);
				}

				// Create a readable stream from the response
				const videoStream = response.body;
				// const videoStream = response.body;

				// const reader = response.body.getReader();
				// const videoStream = new ReadableStream(response.body);

				// Ensure videoStream is a valid readable stream
				if (!videoStream) {
					throw new Error('Failed to get video stream from response');
				}

				// Create a pass-through stream to handle ffmpeg output
				const outputStream = new PassThrough();

				// outputStream.writable = true;

				// Pipe the video stream through ffmpeg to transcode it to mp4
				ffmpeg(videoStream)
					.format('mp4')
					.output(outputStream)
					.videoCodec('libx264')
					.audioCodec('aac')
					.on('start', (commandLine) => {
						console.log('Spawned Ffmpeg with command: ' + commandLine);
					})
					.on('error', (err) => {
						console.error('Error:', err.message);
						console.error(err);
						outputStream.destroy(err); // destroy the stream in case of error
					})
					.on('progress', (progress) => {
						console.log(JSON.stringify(progress, null, 2));
						console.log('Processing: ' + progress.percent + '% done');
					})
					.on('end', () => {
						console.log('Transcoding finished');
					})
					// .pipe(outputStream)
					.run();

				return outputStream;
			} catch (err) {
				throw err;
			}
		}

I get a conversion error ffmpeg 234

I do not want to have to download the entire file first.
