This is a bit off-topic but I wanted to share because it seems a lot of people are running into issues with choppy video playback and stutter on Mac OS X.

I am using a Mac Mini with Snow Leopard (10.6.8) as a home media center and it has worked great in the past, playing back music and videos from multiple sources (web, quicktime, VLC, EyeTV). A few weeks ago the video playback from all my sources started to become choppy, to stutter, and often the picture would hang for seconds at a time. Totally unusable. Drove me nuts for two weeks.

After much research and trial-and-error it turns out the problem was an outdated Flash Player which seems to have messed up the video pipeline for the entire system. The short is, I updated the Flash Player to version 11 directly from the Adobe web site, rebooted the Mac Mini, and all is well again!

Judging from the various posts across the web, video playback appears to be a fairly widespread problem for Mac users and I hope this helps some of you out there! And I can’t wait to get rid of Flash altogether – I can’t remember the times it has crashed my browser, hung my system, and screwed up things. Thanks Adobe ;-(

In case you missed it among the host of announcements at JavaOne (JavaOne 2011: First Wrap-Up):

Java FX 2.0 is now available for Mac OS X as a Developer Preview (download). Also, the NetBeans 7.1 Beta release (download), which includes full support for JavaFX 2.0 as well Java 7, is also available for OS X.

Questions about JavaFX 2.0? Here you can find the ‘short and sweet’ JavaFX 2.0 FAQ page.

Finally, getting started with JavaFX 2.0 is easy: Follow this excellent JavaFX 2.0 Tutorial and learn about Getting Started, Creating a User Interface, Effects, Animation, and Media, Application Logic, API Reference and Deployment.

JavaFX is back!

Some quick updates and links that have accumulated over the past days:

With the release of JDK 7 people have been asking “Where is JDK 7 for Mac OS X?”.

Apple and Oracle engineers are currently actively working on integrating the OS X Java code base into OpenJDK. This initial integration takes time and we can’t yet give you a specific date on the completion.

However, the integration is coming along well. You can check out the details of the Mac OS X Port Project within OpenJDK, see the status on the project wiki, and follow the mailing list. There are also regular (but unofficial) builds available for download.

Stay tuned.

PS: Of course, you can still always get the official Apple OS X JDK 6 implementation through the OS X “Software Update” mechanism.

Apple has recently announced that it would prefer if someone else were to continue the development of the JDK for Mac OS X. As Apple’s own JDK is mature and well-integrated, we would love to see Apple contributing the source code of the existing JDK for Mac OS X to the OpenJDK BSD Port project (
