  • ffmpeg - create videos from images with blur and transition effect [on hold]

    21 février 2018, par QuangPM

    I’m looking for ffmpeg commands to create video from images (img01 -> imgXX) and sound.wav, like :

    • Video background : these images with blur effect
    • Video music : from sound.wav file
    • When image show, it move from left to right on screen, next image when it move out of screen, and have transition effect between images (when playing to next image).

    I would like to create a video like this one : https://www.youtube.com/watch?v=00FTtx73n7Q

  • How to undistort Fisheye sub section

    22 septembre 2022, par Eudie

    How to generate normal views from fisheye view as shown in the image below. enter image description here

    


    Opencv fisheye model flattens the whole image to birds eye view, but that does not produces the desired result.

    


    One approach could be find equations for 4 edges and build map from transformed view to raw view and use cv::remap function to generate image.

    


    Most of security camera maker provides these transform APIs but how can we do it locally.

  • Why is only one of multiple overlayed videos playing in FFmpeg ? [closed]

    27 mai 2023, par Sixtus Anyanwu

    Only one out of multiple overlayed videos is playing FFmpeg

    


    I am trying to overlay 2 playable videos on top of another video in ffmpeg.

    


    ffmpeg -hide_banner -i finalagain.mp4 -i Tatsumaki0trim.mp4 -i Tatsumaki1trim.mp4 -filter_complex "[0][1]overlay=x=(W-w)/2:y=(H-h)/2:enable='between(t,4,8)'[v1]; [v1][2]overlay=x=(W-w)/2:y=(H-h)/2:enable='between(t,0,4)'[v2]" -map "[v2]" -map 0:a -preset ultrafast trial.mp4
