• How do I fix HTTP 404 error message using FFMPEG command ? [on hold]

  18 décembre 2018, par Noob

  I am trying to download a video from this site (https://ffmovies.ru/film/night-school.kk6y4/16qmpp) and have tried using ffmpeg but it always returns an "HTTP Error 404 Forbidden." I’ve also tried using the wget command to consolidate all the ts files but that didn’t work either (I get the same error message). I am not on expert in this and was hoping someone out there can help me fix this problem. Here is the ffmpeg code that I inputed :

  ffmpeg -i https://cdn.mcloud.to/stream/sf:i0:q2:h5:p23:l1/vtYB9rGpyklG1sxXqgdmXg/1545238800/g/9/b/pj11w4/hls/480/480.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

  I have also attached a picture of the error message for reference. I really appreciate someone showing me what I am doing wrong.

  Cheers.

• How to set up my complex filter with zoompan and xfade for ffmpeg using Fluent-FFmpeg .complexFilter method ?

  21 août 2024, par Rémy Groleau

  I'm using fluent-ffmpeg with Node.js. My problem is the setup of my complex filter.

  


  const filters = Array.from({ length: imageCount - 1 }).map((_, i) => {
        const rndInt = Math.floor(Math.random() * 1000) + 1

        return {
            zoompanFilter1: {
                filter: 'zoompan',
                options: {
                    z: 'min(zoom+0.001,1.3)',
                    d: `${imageDuration * 60}`, 
                    x: `iw/2-iw*(1/2-${rndInt}/100)*iw/zoom`, 
                    y: `ih/2-ih*(1/2-${rndInt}/100)*ih/zoom`, 
                    s: '1080x1920', // Output size
                    fps: '60'
                },
                inputs: `[${i}:v]`,
                outputs: `zoomed${i}`
            },
            zoompanFilter2: {
                filter: 'zoompan',
                options: {
                    z: 'min(zoom+0.001,1.3)', 
                    d: `${imageDuration * 60}`, 
                    x: 'iw/2-iw*(1/2-33/100)*iw/zoom',
                    y: 'ih/2-ih*(1/2-33/100)*ih/zoom',
                    s: '1080x1920', // Output size
                    fps: '60'
                },
                inputs: [`${i + 1}:v`],
                outputs: `zoomed${i + 1}`
            },
            xfadeFilter: {
                filter: 'xfade',
                options: {
                    transition: 'fade', // Crossfade transition effect
                    duration: '0.5', // Duration of crossfade in seconds
                    offset: `${imageDuration - 1}` // Offset to start the crossfade
                },
                inputs: [`zoomed${i + 1}`, `zoomed${i}`],
                outputs: `crossfaded${i}`
            },
        };
    });


  


  This is my complete code :

  


  async function createVideo() {
    // Escape file paths for Windows
    const videoPath = path.resolve(__dirname+ '/output.mp4').replace(/\\/g, '\\\\');
    const audioPath = path.resolve(__dirname+ '/output.mp3').replace(/\\/g, '\\\\');
    const backgroundMusicPath = path.resolve(__dirname+ '/background-music.mp3').replace(/\\/g, '\\\\');

    const command = ffmpeg();

    const imagesDir = path.join(__dirname, 'images');
    const images = fs.readdirSync(imagesDir)
        .filter(file => /.(jpg|jpeg|png)$/i.test(file)) // Filter image files
        .sort() // Sort filenames to ensure the correct order
        .map(file => path.join(imagesDir, file));

        images.map((image) => command.input(image))

    const imageCount = images.length;
    const audioDuration = await getAudioDurationInSeconds(audioPath);
    const imageDuration =  Math.round(audioDuration / imageCount)

    const filters = Array.from({ length: imageCount - 1 }).map((_, i) => {
        const rndInt = Math.floor(Math.random() * 1000) + 1

        return {
            zoompanFilter1: {
                filter: 'zoompan',
                options: {
                    z: 'min(zoom+0.001,1.3)', // Reset zoom to 1.0
                    d: `${imageDuration * 60}`, // Duration of the zoom effect
                    x: `iw/2-iw*(1/2-${rndInt}/100)*iw/zoom`, // Center x

                    s: '1080x1920', // Output size
                    fps: '60'
                },

    });
}


  


  My problem is I see the 1 image then the transition and i see the 2 image. After that I'm supposed to see the 3 image but I see the 2 image.

  


  What am I doing wrong ?

  


  I tried switching the inputs: [`zoomed${i + 1}`, `zoomed${i}`] to inputs: [`zoomed${i}`, `zoomed${i+1}`] but it just showed the next image and not a loop of consecutive images.
