[This show is sponsored by The Pragmatic Studio. The Pragmatic Studio has been teaching iOS development since November of 2008. They have a 4-day hands-on course where you'll learn all the tools, APIs, and techniques to build iOS Apps with confidence and understand how all the pieces work together. They have two courses coming up: the first one is in July, from the 22nd - 25th, in Western Virginia, and you can get early registration up through June 21st; you can also sign up for their August course, and that's August 26th - 29th in Denver, Colorado, and you can get early registration through July 26th. If you want a private course for teams of 5 developers or more, you can also sign up on their website at pragmaticstudio.com.]

CHUCK: Hey everybody and welcome to Episode 10 of iPhreaks! That's right, we're on the double digits now! This week on our panel, we have Ben Scheirman.

BEN: Hello from NSScreencast.com!

CHUCK: Rod Schmidt.

ROD: Hello from Salt Lake!

CHUCK: Pete Hodgson.

PETE: Hello from thepete.net!

[Ben laughs]

CHUCK: And I'm Charles Max Wood from DevChat.tv! This week we are going to be talking about "Audio and Video" in your apps.

BEN: So this is where you just launch a UIWebView and point it to remote URL and then you're done?

PETE: I did that once.

CHUCK: All the games that I play, I have to turn the sound off on them.

PETE: I actually did do that once, Ben.

BEN: Yes, it's the quick and easy way to do it.

PETE: Yup, it was surprisingly good. I discovered, we're going to jump straight into rearcane pit of noise, but didn't let you do "Autoplay" on video; Apple doesn't want you to do that. Can you still not do that if you're using native video?

BEN: You can do whatever you want with the native stuff.

PETE: Okay. So for the web one, you can't. But this --

BEN: I think it's just kind of the Safari limitation...

PETE: Yeah [chuckles].

CHUCK: Every browser should do that. That rise me asked, too.

PETE: I think they say it's a battery issue more than anything else like they don't want you firing up the radio to download like 50 maybe, to start offering conserve concept.

BEN: Yeah, they have gotten a little bit more strict on the rules for that, and I don't remember the exact numbers off the top of my head.
