    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • can ffmpeg perform frame wise image calculations ?

    19 décembre 2015, par jlarsch

    I would like to divide each frame of a video by an image that I would like to provide as an additional input. Can ffmpeg perform such image calculations ? I could not find any examples.

    This would be a kind of background correction. The input image is the background, for example the median of a large number of frames.
    (often people use a backgroundSUBTRACTION, but I want to use division)

    currently I am doing this in openCV and python. I process each frame like this :

    (vidMed is the background image)

    import cv2
    
vidIn=cv2.VideoCapture(input.avi)
    
vidOut=cv2.VideoVriter(output.avi)
    

    
while true
    
    ret, frame = vidIn.read()
    
    bgDiv=frame/vidMed
    
    vidOut.write(bgDiv)

    I was hoping this may run faster using ffmpeg

  • ffmpeg combine images to video and specify duration for each image ? [duplicate]

    11 juin, par hanshenrik

    Can ffmpeg combine images to a video with a specific duration for each image ?
For example, i want 1.jpg to be displayed for 100 ms, and 2.jpg to be displayed for 120 ms, and 3.jpg to be displayed for 115 ms, and so on.. can ffmpeg do this ?

    


    I have a bunch of images, each image has their own timestamp, and the timestamps decides how long each image should be in the video..

    


    This is similar to question Conversion of images to video with variable fps using FFmpeg , but unlike that post, I do not need a gradual increase, but I rather need to specify the duration of each image.

    


  • Face replacement by an image in video using FFMPEG android

    18 janvier 2015, par Sanat Pandey

    I am working on FFMPEG Video Conversion, I want a face replacement by my image in a video. For this subject I searched for something which I am describing below. Please let me know if I am wrong, and suggest a more proper procedure for the task.

    1) I can extract all images from a video frame by frame.

    2) Then we detect face from each image.

    3) Morph an image onto the face.

    4) Then again make a video with these images through FFMPEG.

    Am I right ? If yes then what about audio in this process ? And if wrong then where am I mistaken ?
