Automatically generate different resolutions for uploaded videos

Hey everyone! 👋

I’m looking for a way to automatically generate different video resolutions from an uploaded video. My goal is to build a tool that provides multiple resolutions (e.g., 1080p, 720p, 480p) for a video player, but it would be ideal if this could be done automatically through a function after the video is uploaded.

I’m using the self-hosted version of Appwrite (1.6.0) and have been trying to get FFmpeg to work within an Appwrite Function, but I wasn’t able to make it run successfully. I’ve looked at various resources related to FFmpeg, but none of them really helped with this setup.

If anyone has experience with video processing in Appwrite Functions or knows a better approach to handle this, I’d really appreciate your help! 🙏

Thanks in advance!

TL;DR

Developers want to automatically create different video resolutions. They are using Appwrite 1.6.0 and FFmpeg but are facing issues. They seek advice or alternative methods for video processing in Appwrite Functions.
