I read a post detailing how you can call ffmpeg from image magik. I want to learn how to:
- Take a series of screenshots from a video,
- store them in memory (dont' write all images to disk)
- at the end of the video concat all the images and persist a single image to disk.
This is what I'm looking to make. Long story short, this is how youtube generates their hover-preview thing, and I want to replicate that.
I have a nodejs script that can take a number of thumbnails from a video and store them to disk. It's also simple to take some images on disk and combine them into a single image. However, I'd like to optimize this process by not having to store any images to disk until all the images are joined in the final reel.
Any thoughts?
