My latest thought was to use the same pixel format object as the shared context since that particular function already takes the shared context as one of its parameters. Besides, I figure (perhaps incorrectly) that the shared context was build with - [FxHostCapabilities glContextPixelFormatAttributes:]. Steve, Have you tried using the [-FxHostCapabilities glContextPixelFormatAttributes:] method? Does that return the correct results for you? I am using PBuffer_Create (EffectHelpers.mm) in my plugin to set up a pbuffer for drawing. All works well on my computer, but it's failing with error 10009 (invalid share context) on a tester's computer that has multiple monitors and graphics cards. I added some code to the beginning of PBuffer_Create to print out the pixel format info for the shared context (renderInfo.sharedContext) and got the following: The pixel format attributes are set up as follows, which is how Apple's sample plugin code is set up. CGLPixelFormatAttribute pixelFormatAttributes[] = { kCGLPFANoRecovery, kCGLPFAAccelerated, kCGLPFAWindow, kCGLPFADisplayMask, (CGLPixelFormatAttribute )CGDisplayIDToOpenGLDisplayMask(CGMainDisplayID()), kCGLPFAColorSize, (CGLPixelFormatAttribute)(colorDepth * 4), kCGLPFADepthSize, (CGLPixelFormatAttribute)16, (colorDepth > 8) ? kCGLPFAColorFloat : (CGLPixelFormatAttribute)0, (CGLPixelFormatAttribute)0 }; The only change I notice is in the kCGLPFADisplayMask value between the two screens. Would this be the likely cause of the issues I'm seeing, and does it mean that I need to modify PBuffer_Create to set up its CGLPixelFormatObj with the same values for kCGLPFADisplayMask as in the shared context? If so, what do I need to be looking for? steve This email sent to site_archiver(a)lists.apple.com

We test against the version and app in -init and return 0 if the plugin shouldn't load. Does the trick. Some example code follows, if you are interested.

site_archiver(a)lists.apple.com Delivered-To: Pro-apps-dev(a)lists.apple.com Hi Bob, FxPlugs have always been loaded from /Library/Plug-Ins/FxPlug and ~/Library/Plug-Ins/FxPlug. Other types of plugins (After Effects, FXScripts) are loaded from Library/Application Support/Final Cut Pro System Support/Plugins. FxPlugs have a different path because they are meant to be used by multiple applications, not just Final Cut. There's no secret way of preventing a particular plugin from loading, other than removing it from one of the plugin paths. If you have a bundle with multiple plugins, and just want to disable some in the bundle, you'd have to edit the bundle's plist. - Paul On Jun 10, 2010, at 11:04 AM, Bob Currier wrote: > I'm trying to resolve some installer issues dealing with older versions > of FCP, older versions of plug-ins, etc. with the goal of being as > "automatic" as possible.

FxPlug Loading Questions
by Bob Currier 10 Jun '10

10 Jun '10

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com I'm trying to resolve some installer issues dealing with older versions of FCP, older versions of plug-ins, etc. with the goal of being as "automatic" as possible. To that end, I have a couple questions: - Is there a way to keep an FxPlug from loading, along the lines of how After Effects ignores plug-ins if you put parentheses around the filename? - What is the history of plug-in search paths across FCP versions? The official location for FxPlugs is now "/Library/Plug-Ins/FxPlug" (and the user equivalent), but in the past "Library/Application Support/Final Cut Pro System Support/Plugins" was also searched. In fact, in FCP 7.02 I have some older plug-ins which are successfully loading from Application Support, although it won't load my plug-ins from there. -- Bob _______________________________________________ Do not post admin requests to the list.
