How can use ffmpeg in AWS Lambda to clip hls trasnsimision to .mp4
15 novembre 2024, par Bruno MunnéThe ffmpeg input is through the public url of the bucket, I want to save the output in a tmp.mp4 file and I want to upload this file to the bucket. Locally the ffmpeg command works perfectly, lasting no more than 3 seconds and the output file weighs less than 1MB


export const handler = async (event) => {
 try {
 const { m3u8, offset, duration, signedURL } = event;

 const clipKey = `clip_output.mp4`;
 const clipFilePath = path.join('/tmp', clipKey);

 execSync(`/opt/ffmpeglib/ffmpeg -i ${process.env.URL_CLOUDFLARE}/${m3u8} -ss ${offset} -t ${duration} -c copy -f mp4 ${clipFilePath}`)

 const fileContent = fs.readFileSync(clipFilePath);
 const resSign = await fetch(signedURL, {
 method: "PUT",
 headers: {
 "Content-Type": "application/octet-stream",
 },
 body: fileContent,
 });

 if (!resSign.ok) throw new Error(`Failed to upload file to S3: ${resSign.statusText}`);

 fs.unlinkSync(clipFilePath);

 return {
 statusCode: 200,
 body: JSON.stringify({
 message: 'Clip procesado y subido correctamente',
 clipKey: path.basename(clipFilePath)
 }),
 };
 } catch (error) {
 console.error("Error al procesar el clip:", error);
 return {
 statusCode: 500,
 body: JSON.stringify({ error: error.message }),
 };
 }
};



The error it shows me is the following

Error : Output format mp4 is not available
12 avril 2024, par alpaca pwaaI'm using fluent-ffmpeg in my nextjs application, I'm trying to process the video and specified a format to stream on my s3 bucket but it keeps on failing. My terminal keeps on throwing "Error : Error : Output format mp4 is not available". I already verify my ffmpeg format "ffmpeg -format" and confirm that it supports encoding and decoding mp4 files. I've already tried solutions from other forums but it's not working for me.
