I posted an article a while back about a DHTML engine I put on GitHub. I included an example game called Bombada that's also on GitHub. Note: the engine isn't "HTML5" per se (which is becoming more of a buzzword than makes sense) and I've moved on to a canvas engine (which will someday also be open source).

Even better, there was recently a game development contest on Boing Boing which saw 9 pretty cool entires. Ours was called Onslaught! and was written in JavaScript using canvas (though it does fall back to flash for audio).

I've got some substantial experience writing games in JavaScript and HTML5. To me, the biggest hurdle right now is audio. Somebody mentioned the inability to go fullscreen, and while I've seen that handled by the video tag, to me it's not as big a problem as the audio tag being basically unusable for gaming purposes.

Agree with your points on RTMPE. As for full screen capabilities, check out http://jilion.com/sublime/video - very impressive, to my eyes at least. Overlayed controls, true fullscreen, etc, etc, all present and accounted for.

"Apple will have full control over what HTML5 is able to do on the iphone they could limit performance or functionality in a way that would make it pretty difficult to make advanced apps. "

Who needs HTML5 apps? If I was Apple be more worried about someone setting up their own Hulu for iPhone. This HTML5 video works on iPhones and is privately hosted, not pulling from Youtube. Not only does it work, it works very well, loading much faster than Youtube videos do on my 3GS.

Since the iPhone is locked down I'd be more willing to pay to access quality video content on my phone than my PC. Using HTML5 for video someone could create a iTunes competitor today. Come on TV/Movie studios what are you waiting for? Do you enjoy handing Apple 60%, or do you want someone else to create it all and then cry that they're stealing from you?

(And Youtube's player controls are probably far better than anything the average developer could come up with.)

Nope: http://jilion.com/sublime/video
I even get fullscreen in my Webkit nightly. All at about 10% of former CPU usage under Flash on my MBP 2.2 Ghz.

People tend to forget what Flash is. It's a fucking browser plugin. A metaphor from the internet bronze age.

Other browser plugins:

ActiveX
Java Applets
Silverlight
Bonzi Buddy

If your idea of providing a web experience necessitates installation of 3rd party, buggy and half-baked plugins then you fail as a developer and as a human being.

I'll admit, HTML5 media experience is kinda lacking at this point and there are reasons for that. a) the infighting between h.264 camp and Theora camp has resulted in a paralysis where non-ideologues don't know which way to lean. and b) the next generation tools aren't yet available for the web developers so they could start serving their content for the post-Flash era. Every html5 video implementation I've seen is very barebones and not as feature rich as Flash.

Of course, this could change very soon and above 2 points are very fixable. To quote JFK on this matter:

We choose to switch to HTML5... (interrupted by applause) in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too. [followed by stuff about Adobe being lazy]

My point is, if you defend Flash you might as well defend Bonzai Buddy. I don't care if the next version of Flash gives free handjobs - I want it out of my fucking browser.

Hulu is in the content business, if the alliance between the various studios lasts much longer. They're not in the Flash business. What they're running is already H.264, only in a Flash container. And since even H.264 is free for free content for at least five years, I'd say they'll switch over with no problems.

Try to right-click on that. And sorry to say, you can grab the movies from Hulu if you're clever. Flash just hides itself in spaghetti code.

It's not alone in that mission. Google is also pushing HTML5, which will run better than any Flash player devised.

Similar players will no doubt evolve, including ones that accept theora or H.264/x.264. And this developer says it will allow for Internet Explorer by falling back to Flash if necessary.

There's no real need to do so. For starters, they could use this -- just the first of many to come.

That's a beta of a player that works with H.264. If you read down, you see that they want to bring support to Firefox, that it works first with Chrome and Safari and other Webkit browsers. (MPEG LA has said they will not charge royalties for web use for at least the next five years, if you don't charge the user, they won't charge you.) You can also imagine other players choosing other codecs. It depends on what codec you have installed, doesn't it? A website could have ogg and/or H.264 versions installed, as well as Flash -- for Internet Explorer users. (See Sublime's statement about what they're working on for the free release version -- free if you don't charge.

So websites that don't charge = free. If you charge for your video, as does the beta of YouTube Movies -- streaming feature films -- then you'd pay the license fee.

Just try it and see if it isn't impressive. No plugins. The playback is controlled by the HTML5 tag and the player.
