I am working on a mac open source project Wall-E, this project’s purpose is build a video management tools using face to classify videos.
So first step is extract images from videos.
First install ffmpeg, very easy:
brew install ffmpeg
After install ffmpeg, extract image is very easy:
ffmpeg -i xxx.mp4 -r 0.1 -f image2 image-%3d.jpeg
- -i is for the input filename
- -r is for how many frame to extract for 1 second
- -f is for output format
and more can see “How to extract images from a Video using FFmpeg“.
