Begun, The Codec War Has

I just got back last night from WWDC 2017 week — I was speaking at CocoaConf Next Door — and here’s an obligatory selfie to prove it.

Apple TV… Buffering…

Forgive me a little Apple armchair-quarterbacking, but I’m still puzzling over the most under-reported story from this week’s Apple Event: the $30 price cut on Apple TV.

Is this the sound of capitulation?

Oh Look, an H.265 Use Case

Streaming Media has a nice article from a few weeks back on how HEVC Innovation Has Been Fast, But Evolution Will Be Slow, that while it’s great that H.265 can cut bandwidth use by about 40%, it will take a long time to get adoption, since that’ll require encoders, end-user hardware, and so on. It doesn’t work until every step in the chain can use H.265. One frequently-cited application of H.265 is in delivery of 4K video, which will have hideous bandwidth requirements, but that deserves ample skepticism, and risks tying H.265 to the 4K rock… if people realize they don’t need a resolution difference they can’t actually see on home TVs, what’s the point of 4K?

That said, I did realize the other day one scenario where H.265 could really make a difference right now: livestream uploading. When I livestream from home, I have only 1.5 Mbps up (U-verse is the best I can do; the cable modem bandwidth on our cul-de-sac is really sketchy), so I run around 1 Mbps to account for overhead, and end up with a sub-SD picture. When I livestream from public wifi at a conference, I’m sharing the bandwidth with everyone and I’m lucky to get a stream out at all (this is why I’m crazy skeptical of wifi-only livestream cams — when can you ever count on having adequate wifi bandwidth in public?). So the prospect of nearly halving the bandwidth requirements has an immediate payoff: with my 1 Mbps ceiling, H.265 would effectively double my picture quality, so I’d be easily capable of doing 480 SD, and could get into HD the next time U-verse bandwidth improves.
