• ffmpeg - detect frames that have a given image/logo

  13 juillet 2012, par sofia

  I'm trying to split a video by detecting the presence of a marker (an image) in the frames. I've gone over the documentation and I see removelogo but not detectlogo ;)

  Does anyone know how this could be achieved ? I know what the logo is and the region it will be on.

  I'm thinking i can extract all frames to png's and then analyse them one by one (or n by n) but it might be a lengthy process..

  Any pointers ?

  Thanks :)

• Evolution #3431 : Logo de SPIP plus gros

  30 octobre 2017, par b b

  Je n’ai pas vraiment d’avis sur la question (pourquoi donc je commente ^^), mais les sources et les déclinaisons du nouveau logo sont dispos sur la zone https://zone.spip.org/trac/spip-zone/browser/_graphismes_/logos/spip/spip_2017

  On distribue aussi le logo dans le dossier prive dans trois versions différentes, cf :

• Need Help PRO ffmpeg Python input multi video type in folder for overlay logo and output to only mp4 with same or random name please

  29 août 2021, par noobherepleasehelpme

  I need help please
I'm new to python and ffmpeg.

  


  Now I use this basic command To use ffmpeg add a logo overlay to the video file.

  


  import ffmpeg
main = ffmpeg.input('1.mkv')
logo = ffmpeg.input('logo.png')
(
    ffmpeg
    .filter([main, logo], 'overlay', 10, 10)
    .output('2.mp4')
    .run(overwrite_output=True)
)



  


  It works very well, I found it on here.
But is it possible to have ffmpeg to input all mp4 or mkv files in a folder ?

  


  or command ffmpeg Find all types of video files in the folder. (if possible)

  


  and insert the logo with filter overlay as usual

  


  and output to the original file name or random name

  


  thanks please help me
