Sorry for the last reply, I just saw your question!

I want to start by saying that I know that something very confusing with gsvideo at this point is the version numbering. The latest "stable" release listed in the project website is 0.6-pre5. However, I recently stopped to use of this funky "pre" names, and I'm uploading some newer test packages using the release date as the version. The latest one is 20100702, which you can download from here. The reason for this is that I'm not putting up any more stable releases until I finish the 0.6 version with proper Mac support.

So, the macinstall script in the latest test release has some fixes that hopefully solve this dependency issue. If you have the chance to try it out, let me know how it goes.

Just a quick note. If the problem with the libxml continues, you can try the following:

1) open a terminal and change to the directory where the gstreamer binaries are located, something like this
cd <path to libraries folder>/GSVideo/library/gstreamer/macosx

2) Create the following symlinks:
ln -s libxml2.2.7.3.dylib libxml2.dylib
ln -s libxml2.2.7.3.dylib libxml2.2.dylib

Hopefully this helps.

Update: the Snow Leopard package of gsvideo 0.7 should solve these dependency issues.

As for Leopard, I still don't have gstreamer binaries available. If anyone wants to follow the steps I describe here to compile gstreamer on OSX 10.5, I'd appreciate very much :-)

I have a similar error:

I compiled 64 binaries of gstreamer as well, didn't package with GSVideo though because they didn't work from the PDE. I'll upload anyways, so people working with Eclipse in 64 bits can use.

I uploaded a new package of GSVideo 0.7 for OSX Snow Leopard which comes with 64 bits binaries of GStreamer. Grab from here. Let me know if they work fine from Eclipse (I didn't test myself).

it looks like im too stupid!

I added the native path for all gsvideo jar's... any hints?

Are you getting these errors in Eclipse?

Please re-download the 64 bits package of GSVideo for Snow Leopard, since the original one contained broken GStreamer binaries. I just uploaded a fixed version which I have been using successfully to run Processing+GSVideo from Eclipse. Let me know if this solves your problems.

ah, so you have your own, global installation of gstreamer from macports? (I don't know what brew is, btw). In that case it might be conflicting with the gstreamer binaries bundled with gsvideo...

ok, getting the same error... I'll do some debugging and update soon.

Actually the reason for the error was very simple: the osxvideosrc plugin is missing from the 64 bits distribution. For some reason the compilation for 64 bits didn't generate the corresponding library file, while for 32 bits did. This will probably take me some time to figure out. For now I'll recommend you use the 32 bits binaries (in which case you have to switch the JRE environment in Eclipse to 1.5).

Just as an update on this issue (video capture missing in gsvideo 64 bits): it will take a little bit longer as the gstreamer plugin required for this (osxvideosrc) needs to be completely rewritten. I was told that osxvideosrc uses the older 32-bit Carbon QuickTime API, which has been deprecated in 64-bit mode (same reason why Adobe spent so long converting Photoshop CS5 to 64-bit). The plugin needs to be rewritten for the newer Cocoa QTKit API (which will work in 32-bit and 64-bit modes).
