How to extract multiple images contained in HEIC file format?

Question

I have a HEIC file containing multiple images. How can I extract this image sequence in JPEG or PNG format ? Is there a NuGet that simplefies the process?

This is for an image handeling software on android, IOS and UWP. I have been looking for a starting point to write this part of the code.

Are you trying to extract those frames using the iOS|macOS framework or if doing this on a server then you can just use something like ffmpeg (HEIC is just a container and in an image-burst-based HEIC, there is an embedded hevc/hvc1 video stream (actually there are multiple streams) and you can extract these to "frames" – Karolekarolina

Well i am trying to do this offline with-in an Android app / UWP app. – Knuckleduster

So i found this Library to help with this Issue. – Knuckleduster

So i found this Library Work-Stuff - HEIF.NET that claims to decode and convert HEIF Images and Videos in .NET. I dont know how i can impliment it into my library tho ! on the other hand this strukturag - libheif comes up often researching the topic .. – Knuckleduster

@Karolekarolina can you please provide an ffmpeg command for achieving it? I've been trying to see the streams using ffprobe like ffproble file.heic but it gives [mov,mp4,m4a,3gp,3g2,mj2 @ 000001ab23e4da00] moov atom not found. And my ffmpeg build was built with --enable-libx265 support. – Amphimixis
