Hi again,

Seems to be some kind of deadlock in the Swing DnD implementation on OS X when interacting with native code. I’ve seen that happen before.

Wrapping the loadURI call in a SwingUtilities.invokeLater solves the problem. :-)

Hi Kiril,

Nice work!

I’ve downloaded the official Mac/OS X distribution, did some changes to your app to make it work with 1.5 (DnD stuff). Added /Library/JavaFX/Home/lib/desktop to java.library.path.
The app compiles and runs, but all I get is the spinning beach ball of death.. Seems to hang on the call to
new MediaProvider(uri);
(probably in some native code).

Anyone has an idea on how to get passed this?

Thanks,

Hi Kirill, excellent work! It’s certainly an exciting time.

Have you found a way to properly dispose of the MediaProvider instances? Simply pausing and setting the reference to null does not kill the background thread, and I haven’t come across a dispose method or similar.

Any ideas?

Cheers, Fred

Alex,

This entry is hardly the right place to report problems with JavaFX. Search the JIRA tracker for open issues, and if there is nothing matching, create a new one.

Thanks
Kirill

Memory leaks! On Windows, the following code will chew up 1MB.

File f = new File(“C:\\MoreTests\\clocks.wma”);
long free = Runtime.getRuntime().freeMemory();

for(int i=0; i<100; i++) {
MediaProvider provider =
new MediaProvider(f.toURI());
System.gc();
System.out.println(“Usage ” + i + “: ” +
(free Runtime.getRuntime().freeMemory())/1024.0);
}
System.gc();
System.out.println(“Usage ” + (free – Runtime.getRuntime().freeMemory())/1024.0);

Hi, I just downloaded the JMC jar and natives for mac os x and the players are working on .mov files, etc. I can’t seem to find any javadocs or src code for JMC. I’d like to be able to get at the pixels so that I can copy them into an openGL texture, etc, the way you can using FOBS4JMF (or rather used to be able to– there is an issue with FOBS4JMF on 64-bit macs using 1.6).

Anyhow, I except for your blog and a single pdf from a java conference this summer I can’t find *any* examples using JMC directly from Java.

Thanks, sj

JavaFX 1.0 is launched…

You can view the updated site, launch videos, sample apps, and more, at javafx.com .. well .. when the server comes back up, it’s having a little bit of trouble at this moment. Anyway, I want to post a few……

The codec support is system dependent. Windows support is via DirectShow and the on2 codecs which don’t support Quicktime, mp4, h264 out of the box, but things worked very well with an ffdshow-based Direct Show filter pack. I used k-lite codec pack.

Mac codec support is coming through CoreVideo so all the mp4, .mov videos should be supported out of the box.

Good stuff and good performance so far.

Tony – you can see the jar / dll sizes on the download site. And this does not require 6u11 – i’ve ran this on two machines, one with 6u10 and another with 6u11.

Good to hear about the sneak peek it helps alot!!

So how many bytes are these dlls or more importantly when they are in a jar? As mentioned previously web start does support native libs.

And what about Linux support?

Does this require 6u11? Since you did not mention it I am assuming you are using 6ux?

Sorry for the questions I am really looking forward to this update.

Best Regards,
Tony
