• How to set min, max and avg bitrate or vbv delay using FFMPEG for livestream in Python ? [closed]

  10 mai 2024, par Tebyy

  I'm trying to set the minimum, maximum, and average bitrate or vbv delay for a WebM livestream in Python using FFMPEG, but it still shows "0" or "N/A". I've checked the documentation, and everything seems correct. I've also searched for solutions online, but none of them have solved my problem. Does anyone know what I might be doing wrong and how it should be done correctly ?

  


  FFMPEG Command :

  


  ffmpeg_command = [
        'ffmpeg', '-f', 'rawvideo', '-pix_fmt', 'bgr24',
        '-s:v', '1920x1080', '-r', '60',
        '-i', '-',
        # '-an',  # Turn off the audio track
        '-c:v', 'libvpx-vp9', '-g', '60', '-keyint_min', '60',
        '-b:v', '6M', '-minrate', '4M', '-maxrate', '12M', '-bufsize', '8M',
        '-crf', '0', '-deadline', 'realtime', '-tune', 'psnr', '-quality', 'good',
        '-tile-columns', '6', '-threads', '16', '-lag-in-frames', '16',
        '-f', 'webm', '-'
    ]

• Error : Output format mp4 is not available

  12 avril 2024, par alpaca pwaa

  I'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.

• How can use ffmpeg in AWS Lambda to clip hls trasnsimision to .mp4

  15 novembre 2024, par Bruno Munné

  The 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 }),
        };
    }
};
