My question is How to use lintel to get the same results of the following ffmpeg command ffmpeg -v quiet -skip_frame nokey -i video.mp4 -vsync passthrough img_%04d.jpg Thanks

Good question, it's not supported currently, so I could take a look at adding it. Out of curiousity, what would your use case be?

I want to only use the key frames for video classification task. Thanks @dukebw
