Up and Running with Node.js

For maximum compatibility, here’s what your video workflow will look like:

1. Make one version that uses Theora video and Vorbis audio in an Ogg container.
2. Make another version that uses WebM (VP8 + Vorbis).
3. Make another version that uses H.264 baseline video and AAC “low complexity” audio in an MP4 container.
4. Link to all three video files from a single <video> element, and fall back to a Flash-based video player.

web content intended for the desktop might work well on iPhone without any modifications. Some differences exist, however, so at a minimum you should ensure that your webpages are compatible with Safari on iPhone OS. Next, you might optimize your webpages for iPhone OS simply as a convenience to the user. For example, ensure that your webpages work over Wi-Fi, 3G, and EDGE, scale correctly when rendered, and contain media that is viewable on iPhone OS. Finally, you might build custom web applications for either platform that look and behave like native applications.
