> video with only a single key frame at the beginning
I've literally never seen a video like that in my life, but I'd still expect it to work. Just decode everything starting from frame 1. My desktop can decode H265 at 1,666 fps. I can wait.
That blows up pretty quickly though? Even a 10 minute video will take in the worst case ~20 seconds to decode at that rate.
Not really an excuse not to have it (since most video wont be encoded in such an insane way), but the developers owe no obligation to users to implement it.
