VP6-encoded Flash video doesn't run on the iPhone, so that's not what he was referring to.

I believe Jobs is talking about comparing two videos on the iPhone, with hardware accelerated video lasting 10 hours and non-accelerated video lasting 5 hours. You may not notice if you're not paying attention to battery while you watch video.

To the sibling comment here, I'm not referring to profiles. I'm referring to the fact that various implementations of H.264 encoders produce content that, depending on the implementation, may or may not be accelerated by the iPhone's PowerVR SGX 535.

One can produce a pair of H.264 encoded in .mp4 container movies, encoded from the same mpeg2ts original, one of which can use hardware acceleration, and the other of which cannot.

(I haven't had the chance to check yet if Adobe's 'Gala' responds the same way to such files on the desktop Macs Gala supports.)
