CameraPlugin support for Mac OS?

Is it true that there is no CameraPlugin support for Mac OS?

Hmm, to my surprise that seems to be correct. I can’t even find source code for it in ancient scratch releases. I have trouble believing it doesn’t exist somewhere since actually running an original Mac Scratch does load a CameraPlugin. Since you’re working with John M, maybe asking him about where the code went would work...

I haven't lost my mind; it's backed up on tape somewhere.

No, I compiled the CameraPlugin for the MacOS VM 4.2.5beta2U in 20/Sep/2014, I send to David Lewis to post in the ftp site.

The VM is the older original interpreted VM, but I tested with the Cog VM, and works. I am appending the CameraPlugin.st for the image:

That’s not the missing part Javier - it’s the mac os specific platform files that seem to be missing. Do you have platforms/Mac OS/plugins/CameraPlugin ?

A version of This CameraPlugin.st with some cosmetic changes seems to
be in the VMMaker package already. As Tim wrote, the implementations
of CameraOpen(), CameraGetFrame(), etc. are not in the VM source as
Tim said.

I tried to run the test code in the st file on 'Croquet Closure
Cog[Spur] VM [CoInterpreterPrimitives VMMaker.oscog-eem.1405] 5.0' but
it does not run (as expected).

Is in the Scratch plugins :

and I forget that also have the CameraPlugin.st

That doesn’t appear to have the actual mac specific sources that implement calls like CameraClose, CameraExtent etc.

It must work in some combinations... I copied CameraPlugin.bundle to
the Resources of my Squeak 4.2.5beta1U, and when I try a few things,
"Smalltalk listLoadedModules" shows 'CameraPlugin' in the list. But
still it fails with 'no camera'.

But http://download.scratch.mit.edu/source-code/ScratchPluginSrc1.4.zip
has the source code. I'll poke around it and see if I can make it
work.

Unless I managed to delete the entire relevant directory from my copy (which I’ll admit isn’t impossible!) it doesn’t exist in that zip.

Thanks. It seems identical to code that is available on the MIT scratch site.

I might be doing something totally wrong... But here is a step I did
and got into an interesting situation:

Step 1:

- Get the source code.

git clone [hidden email]:OpenSmalltalk/opensmalltalk-vm.git

- As suggested, run the updateSCCSVersions script.

./scripts/updateSCCSVersions

- change directory to build.macos32x86/squeak.cog.spur and run mvm with -d.

cd build.macos32x86/squeak.cog.spur; run mvm with -d.

This successfully creates an executable and bundles. But I noticed
that bunch of files are taken from subdirectories under 'iOS', not
'Mac OS'.

Step 2:

To add the CameraPlugin source, copy the set of files (CameraPlugin.c
CameraPlugin.xcodeproj CameraPlugin_Prefix.pch English.lproj
Info.plist osxCameraOps.c sqCamera.h version.plist) into a new
directory: platforms/Mac OS/plugins/CameraPlugin, and add CameraPlugin
to plugins.ext.

- run mvm -d and it does not link osxCameraOps.c and linker fails.

- Then I noticed that other plugins are using the platform-specific
files from the 'iOS" directory. I created CameraPlugin directory
under platforms/iOS/plugins and copy files.

- run mvm -d and it does not link osxCameraOps.c and now the build
process detects those files and produces a compile time error.

If I'm not mistaken, the build process is looking at the iOS platform
files. Is this true?

Besides that the osxCameraOps.c uses QuickDraw functions but it seems
that they are not exposed anymore. I would have to rewrite it.

Re: CameraPlugin support for Mac OS?

MAC OS is the legacy carbon platform.

The cocoa & iOS apps are built from the iOS tree.

There is no more carbon. Yes proper OS-X 10.7 onwards support is needed.

I am making a bit of progress and writing a new primitives against
Apple's AVFoundation library, which promises better performance and
better control over settings.

I like:

- I can write Cocoa bindings in (at least) Objective-C so that calling
API is easier than using objc_msgSend().
- adding EXTRALIBS is isolated for each, so once I figure out that is
what to do, I can add bundle specific -framework, and it works.

Re: CameraPlugin support for Mac OS?

My OS X/iOS CameraPlugin support code, based on Apples new
AVFoundation framework, is getting in shape. There are some clean up
needed and need to figure out a way to add a better way to handle
camera parameters, and also I need to make a minor modification to
make it compatible with iOS, but the basics is working. When I figure
out "how to contribute", I'll make a request.
