Using FCP AE I can read a project into my app select a sequence (or get a modified version XML live). If I modify the sequence and send it back to the FCP project I could add a new UUID to it. But obviously FCP is still creating it's own UUIDs during import and so I can't use the "kFCPOpenItemInProject" as I don't know the UUID. The only option I currently see is to send two sequences: the original one with an "add" flag (so I forget the UUID) and the new one with a "replace" and the same UUID as the original one. I haven't tested that and I hope there is an easier way. P.S. Sure I can get the complete project in again, but that wouldn't be helpful at all. This email sent to site_archiver(a)lists.apple.com

It also lists out all the parameters and their ranges on each installed effect. So if you were writing a simple application that wanted to put a star iris on a piece of media, and you wanted to make sure that there was a star iris on that machine, or else use some other effect, this query would enable that. It is unfortunately slow the first time for a given launch since all the templates and effects have to be loaded to get at the parameters available. Subsequent usage of any effect will be much faster though since they're all fleshed out. Does somebody know what the new "kFCPGetAllEffectsXML" is good for. Is it just a listing you should process with another parser? This email sent to hju(a)apple.com This email sent to site_archiver(a)lists.apple.com

Re: malloc error when repeatedly calling getInputBitmap in an FxPlug plug-in on FCP

You're not doing anything wrong. We don't free the memory allocated by -getInputBitmap when the bitmap is released; instead, we wait until the call to - renderOutput returns. The result is that if you retrieve many input bitmaps during a single render call, you can run out of memory. We're aware of the problem and hope to fix in in a future update. Until then, I think you'll have to accumulate analysis data as you render frames, rather than doing everything in one pass, if that's possible. Adding the following code into the renderOutput section of the SimpleMatte sdk plug-in: double theTime; for(theTime=0; theTime<900; theTime+=0.5f) { FxBitmap * theBitmap = NULL; [getAPI getInputBitmap:&theBitmap withInfo:renderInfo atTime:theTime]; [theBitmap release]; } gives a malloc error in the console of the form: Final Cut Pro(21811,0xa000d000) malloc: *** vm_allocate (size=6234112) failed (error code=3) Final Cut Pro(21811,0xa000d000) malloc: *** error: can't allocate region Final Cut Pro(21811,0xa000d000) malloc: *** set a breakpoint in szone_error to debug Am I failing to free some memory, or is there an internal issue in FCP? It appears to only give this error when applied to an actual imported clip (as opposed to one created by a generator effect). In case you're wondering why any such code should exist, I need to do an analysis pass through the sequence in one plug-in. _______________________________________________ Do not post admin requests to the list.

ProgressAPI problem with HDV codecs

I've filed bug #5627030. To produce this apply the Slow_SolidColor example from the FxPlug SDK to a sequence using, say, HDV1080i60. Increase the delay parameter to 3 or more seconds and you should the beachball cursor (if not change the parameter a couple times). Using PhotoJPEG, we only see the animated cursor.
