  • creating thumbnails from multiple videos

    28 septembre 2020, par blue

    I have multiple videos, and i want to create a thumbnail image for each video.i also want the image thumbnails to have the same names as the videos and have specific width/height.

    
Is it also possible to have ffmpeg create thumbnails with a specific aspect ratio and instead of stretching the video it could add black bars ?

    
Now i don't know a thing about how ffmpeg works so i looked up a tutorial online and configured it,tested out a simple script and it worked.

    
i found what the script i was looking for but i don't know a thing about bash scripts so it just throws an error and i don't how to figure it out.

    


    for f in *.mp4; do ffmpeg -i "$f" -ss 00:00:03 -vframes 1 -s 480x320 "${f%.mp4}.jpg"; done


    


  • How to use ffmpeg to merge the median of pixels in 2 videos

    24 avril 2020, par jocelyn

    I'm new to coding and ffmpeg so please go easy on me !

    



    I am trying to merge 2 videos (they are identical) using the median of the each pixel. I have to use ffmpeg to do this but am unable to find any information online.

    



    I have managed to merge 2 identical videos using the average of each pixel using the following command(I think at least, I'm not sure how to tell if this worked but the command didn't give any errors so I assume it did)
- "ffmpeg -i video1.avi -i video2.avi -filter_complex "blend=all_mode='average'" mergedvideo.avi"

    



    Can anyone help provide more information on how I can use ffmpeg to merge the videos using the median of each video pixel ?

    



    Thanks in advance !

    


  • concatenating multiple url's with ffmpeg

    8 mai 2021, par JohnTerry

    I am trying to concat multiple urls with ffmpeg. let's say i have 4 urls which i want to concat and instead of adding those urls into files.txt manually, I want them to add them automatically.

    


    the command i am using is-

    


        file = "/home/xyz/Desktop/abc/files.txt"
    out = "/home/xyz/Desktop/abc/output.mp4"
    cmd = "ffmpeg -f concat -protocol_whitelist file,http,https,tcp,tls,crypto -safe 0 -i {} -c copy {}".format(file,out)
    os.system(cmd)


    


    now is there any way to put the online urls in files.txt automaticlly ?
