Hi Taiwo, thanks for the amazing article, particularly learned something new from the socketIO section, your explanation of how it was work was brilliant.
As for Durator, it didn't work for me, it asked for a link to any media file and I put a youtube link but Generate button wouldn't click; As for metaworka, I uploaded a png thumbnail file but got a response that it was a video and the frame rate was 25 fps.
I also have a question about the diagram under caching for speed section: why is cache a separate block when it is actually been handled by the same Redis, you mentioned that you map the URL to a UUID and to the result, shouldn't it go to Redis straight, get processed by FFPROBE and return back to Redis cos the cache looks like a separate entity
something like this
