The archive isn't very good for the thread. Is that what they said though? From the comments I see they said "we're working on it, but we're busy with XYZ" and then months passed.
Archive won't load the remaining 3 items for me.
100% my assumptions but:
They were never really working on it, they thought it would just go away. Maybe some junior/senior dev took a shot at it, gave a project plan and it went nowhere.
Yes it's not loading on the archive but I was following the thread closely, it was said recently within the last few months which prompted further discussion and this action by ffmpeg.
