alt Hacker NewsIf the video is streaming, people don't really care if a few frames drop, hell, most won't notice.
It's only when several frames in a row are dropped that people start to notice, and even then they rarely care as long as the message within the video has enough data points for them to make an (educated) guess.

Okay but now you're explaining that correctness is not necessarily the only reasonable state. It's possible to sacrifice some degree of correctness for enormous gains in performance because having absolute correctness comes at a cost that might simply not be worth it.
P/B frames (which is usually most of them) reference other frames to compress motion effectively. So losing a packet doesn't mean a dropped frame, it means corruption that lasts until the next I-frame/slice. This can be seconds. If you've ever seen corrupt video that seems to "smear" wrong colors, etc. across the screen for a bunch of frames, that's what we're talking about here.
