• Recursively convert images in each subfolder into individual videos using FFmpeg

  17 décembre 2024, par arutan edram

  I am using this script to convert all images in a folder into a video. Each image is shown for 4 seconds and the script runs from a bat file.

  


  `ffmpeg -framerate 1/4 -i %%03d.jpg -pix_fmt yuv420p video.mp4`


  


  I have hundreds of subfolders each containing images with the same resolution and I want to convert them into one moive per subfolder.

  


  I might be close to a solution but it still does not do the job

  


  @echo off
setlocal enabledelayedexpansion

:: Set the frame rate and file format
set "framerate=1/4"
set "image_format=%%03d.jpg"
set "output_video=video.mp4"

:: Traverse all subfolders
for /d /r %%F in (*) do (
    echo Processing folder: %%F
    cd "%%F"
    :: Check if images exist
    if exist "%image_format%" (
        echo Converting images in %%F to video...
        ffmpeg -framerate %framerate% -i "%image_format%" -pix_fmt yuv420p "%%~nxF.mp4"
    ) else (
        echo No images found in %%F, skipping...
    )
    cd ..
)


  


  Any help is appreciated

  


• FFMPEG conversion images to video PHP [on hold]

  Hello I would like to know what code in php I have to use to create a video from some JPG images.

• Put images on video with ffmpeg in Node.js

  27 juin 2022, par Cery

  I am creating a server-side video renderer in node.js. I need to add images on an existing video file every frame. I need to set the specific position of each frame in the rendered video. I am holding all the frames of the images in Readable. This is my code that works, but does not take into account the position of the images. How can I modify it ? Of course I have a list with images coordinates - but I don't know how to make a filter out of this.

  


  this.stream is a list of images.

  


    const filter = ["[1:v]format=argb,setpts=PTS+" + 0 + "/TB[out]",
        {
            filter: "overlay",
            options: {
                enable: "between(t," + 0 + "," + 9 + ")",
                x: "0",
                y: "0",
            },
            inputs: "[0:v][out]",
            outputs: "tmp",
        }

        ]
        const Options = [
            "-crf 16",
            "-f mp4",
            "-vcodec libx264",
            "-movflags frag_keyframe+empty_moov",
            "-pix_fmt yuv420p",
        ];

        var ffmpeg = require('fluent-ffmpeg');
        ffmpeg.setFfmpegPath(ffm.path);
        var command = ffmpeg();

        const outputStream = fs.createWriteStream(this.Path + "test.mp4");

        command.input(this.Path + "input.mp4");
        command.input(this.stream).inputFPS(23);
        command.outputOptions(Options);
        command.fps(23);

        command.complexFilter(filter, "tmp");

        command.output(outputStream);
