This article describes how you can use ffmpeg to export a frame of a video file as a PNG image using the following command:
ffmpeg.exe -i input.mkv -vf select=gte(n\,360) -vframes 1 output.png
My question is what -vf select=gte(n\,360)
really does and how it works. I could not find any documentation on this, neither in the official documentation or elsewhere on the internet.
From the context I know this tells FFmpeg to use the 360th frame, but I would like some further documentation on how to use this. What does gte
mean and what is n\,
?
