I had no luck to compile a sample code provided by apple with Xcode 16.0 beta 5. ScreenCaptureKit demo (https://developer.apple.com/documentation/screencapturekit/capturing_screen_content_in_macos) The part it is failling is, streamOutput.capturedFrameHandler = { continuation.yield($0) } And the error message is Sending '$0' risks causing data races Task-isolated '$0' is passed as a 'sending' parameter; Uses in callee may race with later task-isolated uses Please enlighten me why this is an issue and how to avoid? Thanks in advance!

NSPanel *panel = [[myPanel alloc] initWithContentRect:NSMakeRect(100, 100, 400, 300) styleMask:NSWindowStyleMaskTitled | NSWindowStyleMaskClosable backing:NSBackingStoreBuffered defer:NO]; [panel setLevel:NSFloatingWindowLevel];//无效？？？？ [panel makeKeyAndOrderFront:self]; 问题：在FxPlug4.3中使用setLevel不能将panel放在Final cut pro和Mition的前面？ 救命～～～全世界都没找到答案！

1.在Fxplug4.3的 FxRemoteWindowAPI 的协议中，没有提供window.frame.origin的设置。 2.如果我自定义NSWindow时，在FxPlug中 [Window setLevel:NSFloatingWindowLevel];也没有执行。 3.请问我应该如何把窗口保留在Final cut pro的前面，并且不影响Final cut pro 的操作呢？

Hello everyone, I have been receiving this same crash report for the past month whenever I try and export a Final Cut Pro project. The FCP video will get to about 88% completion of export, then the application crashes and I get the attached report. Any leads on how to fix this would be greatly appreciated! Thank you. -Lauren

I have generated FCPXML, but i can't figure out issue: <?xml version="1.0"?> <fcpxml version="1.11"> <resources> <format id="r1" name="FFVideoFormat3840x2160p2997" frameDuration="1001/30000s" width="3840" height="2160" colorSpace="1-1-1 (Rec. 709)"/> <asset id="video0" name="11a(1-5).mp4" start="0s" hasVideo="1" videoSources="1" duration="6.81s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/11a(1-5).mp4"/> </asset> <asset id="video1" name="12(4)r8 mute.mp4" start="0s" hasVideo="1" videoSources="1" duration="9.94s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/12(4)r8 mute.mp4"/> </asset> <asset id="video2" name="13 mute.mp4" start="0s" hasVideo="1" videoSources="1" duration="6.51s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/13 mute.mp4"/> </asset> <asset id="video3" name="13x (8,14,24,29,38).mp4" start="0s" hasVideo="1" videoSources="1" duration="45.55s"> <media-rep kind="original-media" src="file:///Volumes/Dropbox/RealMedia Dropbox/Real Media/Media/Test/Test AE videos, City, testOLOLO/video/13x (8,14,24,29,38).mp4"/> </asset> </resources> <library> <event name="Untitled"> <project name="Untitled Project" uid="28B2D4F3-05C4-44E7-8D0B-70A326135EDD" modDate="2024-04-17 15:44:26 -0400"> <sequence format="r1" duration="4802798/30000s" tcStart="0s" tcFormat="NDF" audioLayout="stereo" audioRate="48k"> <spine> <asset-clip ref="video0" offset="0/10000s" name="11a(1-5).mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> <asset-clip ref="video1" offset="12119/10000s" name="12(4)r8 mute.mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> <asset-clip ref="video2" offset="22784/10000s" name="13 mute.mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> <asset-clip ref="video3" offset="34544/10000s" name="13x (8,14,24,29,38).mp4" duration="0/10000s" format="r1" tcFormat="NDF"/> </spine> </sequence> </project> </event> </library> </fcpxml> Any ideas?

Hi, Could you please explain how to use SF Symbols animations in Final Cut? I would greatly appreciate your help. Thank you!

Recently I've been trying to play some AV1-encoded streams on my iPhone 15 Pro Max. First, I check for hardware support: VTIsHardwareDecodeSupported(kCMVideoCodecType_AV1); // YES Then I need to create a CMFormatDescription in order to pass it into a VTDecompressionSession. I've tried the following: { mediaType:'vide' mediaSubType:'av01' mediaSpecific: { codecType: 'av01' dimensions: 394 x 852 } extensions: {{ CVFieldCount = 1; CVImageBufferChromaLocationBottomField = Left; CVImageBufferChromaLocationTopField = Left; CVPixelAspectRatio = { HorizontalSpacing = 1; VerticalSpacing = 1; }; FullRangeVideo = 0; }} } but VTDecompressionSessionCreate gives me error -8971 (codecExtensionNotFoundErr, I assume). So it has something to do with the extensions dictionary? I can't find anywhere which set of extensions is necessary for it to work 😿. VideoToolbox has convenient functions for creating descriptions of AVC and HEVC streams (CMVideoFormatDescriptionCreateFromH264ParameterSets and CMVideoFormatDescriptionCreateFromHEVCParameterSets), but not for AV1. As of today I am using XCode 15.0 with iOS 17.0.0 SDK.

Hi, trying to wrap my head around Xcode's FXPlug. I already sell Final Cut Pro titles for a company. These titles were built in motion. However, they want me to move them to an app and I'm looking for any help on how to accomplish this *What the app should do is: Allow users with an active subscription to our website the ability to access titles within FCPX and if they are not an active subscriber, for access to be denied.
