The main iTransmogrify! script has been updated with a bunch of new functionality:

• YouTube.com pages are now supported (see notes)
• Daily Motion videos are supported for new-style urls (see notes)
• Kink.fm player and listings page are now supported
• Sideload.com play links are now supported
• WordPress Blogs using Viper Video QuickTags are supported for YouTube
• All media links now open into new windows, so you won’t have to re-transmogrify a page with several media files after playing one. Note that this is dependent on the iPhone, sometimes it will blank other windows)
• Some content in iframes will now be converted.
• MotionBox, Viddler and Vimeo embedded videos, while not supporting iPod/iPhone alternate content, now link to their respective detail pages.

The main bookmarklet code was updated. This was necessary to workaround a frustrating oversight with Google Code hosting. Everyone will need to update their bookmarklet, in the future all updates will be automatic.

This has turned out to be far bigger than I ever imagined. Thank you to everyone for the links, feedback, compliments and ideas.

Known issues

LiveJournal pages redefine a bunch of core JavaScript functionality, breaking all kinds of stuff including jQuery. Additionally, they’re serving media in an iframe from a different domain, meaning JavaScript couldn’t access the frame even if they hadn’t broken it.

Notes

YouTube Internal pages
Because of a strange iPhone quirk, these links all need to go through the Google redirector, otherwise they bounce back to uk.youtube.com instead of playing.

DailyMotion
DailyMotion videos using new-style urls, which are usually about six digits long, work correctly. Videos using the old-style alphanumeric ID do not work yet. I’m probably just going to resort to building a simple web-service to grab those. Additionally, there is no way to programatically access the mp4 alternate content url, so I just linked to their iPhone pages. I’d prefer embedding QuickTime directly, but it’s just not possible yet.

iTransmogrify! is a bookmarklet for iPhone which transforms embedded Flash content into direct links to natively supported formats. That means YouTube videos and MP3s can now be played from the iPhone’s Safari web browser with just a few clicks.

Seeing it work is the best explanation:

On an iPhone? Try it now: iTransmogrify! (works in Safari and Firefox too)

Sorry, it took YouTube a long time to re-encode that for iPhone, here’s a baby panda:

Installation

To install the bookmarklet, just drag the link to your Safari or Firefox Bookmarks, IE users should right click and choose “Add To Favorites…” After adding the link, sync your iPhone.

Grab it now: iTransmogrify!

You can also add iTransmogrify from your iPhone!

More information, source code and bug-tracking is available on the iTransmogrify Google Code page.

Currently supported content:
• Default YouTube Object-Embed code
• YouTube bare Embed
• YouTube bare Object
• A variety of Flash-based MP3 players including Digg Podcasts

Lots more added: iTransmogrify update

Support for other embedded media sites will be added as I figure them out. Please report broken sites or suggest additional sources using Google Code issue tracker.

• Mike West’s Scope in JavaScript was the refresher I needed to resolve one especially annoying object-scope bug.

Also, John Resig’s amazing jQuery JavaScript library. This project was the excuse I’d been looking for to finally dig in and learn it.

The name came from a late-night brainstorming chat with Bruce and was far more fun and interesting than the utilitarian ones I was thinking of. So thank you Bruce, and of course, Bill Watterson.

Valerio Proietti, author of the MooTools JavaScript framework wrote a benchmarking tool called SlickSpeed. This tool runs a number of JavaScript libraries against a suite of CSS selector tests. The source is available from Google Code, I downloaded a copy so I could run tests against the most recent versions of Prototype, MooTools and JQuery against one another.

Results are in milliseconds (ms), smaller numbers are better. Asterisks indicate errors returned during the test.

All tests were served and run from a MacBook Pro 2.16 GHz Core Duo, iPhone tests were run on a 1st Generation 8 GB model. Firebug was disabled for the Firefox tests.

A few things which are immediately apparent:

MooTools is a solid performer. Not the fastest and not the slowest, but Valerio Proietti’s code is consistently impressive.

JQuery has gotten significantly faster in the most recent version, John Resig is also writing really good code.

At least as applies to Valerio’s set of selector tests, JQuery is the fastest library on iPhone, nearly twice as fast as MooTools and almost three times faster than Prototype. Joe Hewitt’s iUI project uses Prototype, how much would iPhone performance benefit from switching to JQuery?

The Webkit team is writing some seriously crazy speed optimizations. If they could just get Safari to stop leaking memory we’d be all set (don’t go looking all smug Firefox, you’re standing in a puddle). As it stands now, when Leopard ships Safari will have the fastest JavaScript engine available. The difference between jQuery and Prototype on Webkit and iPhone is surprising, iPhone runs JQuery nearly three times faster than Prototype using the same browser core.

Firefox runs faster in virtualized Windows than it does native on the Mac. Camino (Mac native version of Mozilla/Firefox/Gecko) was slightly faster, but still not as fast as Firefox Windows.

I’ve got one project wrapping up soon which used MooTools and I’ve been very happy with it. Lately I’ve been reading a lot of buzz about JQuery and might be working that into another project. These tests were mostly just done to satisfy my own of curiosity.
