When a filter is applied, source over compositing resulting in (unexpected behavior) filter bleeding into the background (the color of the background image is changing to gray). I had to use CIBlendWithAlphaMask setting the foreground image as the mask to work around this issue. CIFilter *tonalFilter = [CIFilter filterWithName:@"CIPhotoEffectTonal"];         [tonalFilter setValue:filterImage forKey:kCIInputImageKey];         video1FilteredImage = [tonalFilter valueForKey:@"outputImage"]; CIFilter *colorGenerator = [CIFilter filterWithName:@"CIConstantColorGenerator"];                 CIColor *inputColor = [[CIColor alloc] initWithColor:currentInstruction.compositionBackgroundColor];                 [colorGenerator setValue:inputColor forKey:@"inputColor"];                 CIImage *colorBackgroundImage = [colorGenerator valueForKey:@"outputImage"]; CIFilter *sourceOverCompositing = [CIFilter filterWithName:@"CISourceOverCompositing"];                 [sourceOverCompositing setValue:video1FilteredImage forKey:kCIInputImageKey];                 [sourceOverCompositing setValue:colorBackgroundImage forKey:kCIInputBackgroundImageKey];                 video1FilteredImage = [sourceOverCompositing valueForKey:@"outputImage"];

Using the following code, RAW/DNG images loose their location data when exported to a different device or computer. [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{             PHAssetResourceCreationOptions *options = [[PHAssetResourceCreationOptions alloc] init];             options.shouldMoveFile = YES;                          PHAssetCreationRequest *creationRequest = [PHAssetCreationRequest creationRequestForAsset];             creationRequest.location = locManager.location;             if(rawEmbedsJPEGOnOff == 0){                 [creationRequest addResourceWithType:PHAssetResourceTypePhoto data:photoData options:nil];                 [creationRequest addResourceWithType:PHAssetResourceTypeAlternatePhoto fileURL:temporaryFormatFileURL options:options]; // Add move (not copy) option             }             else if(rawEmbedsJPEGOnOff == 1){                 [creationRequest addResourceWithType:PHAssetResourceTypePhoto fileURL:temporaryFormatFileURL options:options];             }         } completionHandler:^( BOOL success, NSError *error ){             if(!success){                 NSLog( @"Error occurred while saving raw photo to photo library: %@", error );             }             else{                 NSLog( @"Raw photo was saved to photo library" ); }];

AVFoundation setPreferredPolarPattern AVAudioSessionPolarPatternStereo returning no audio on iOS 15. AVAudioSessionPolarPatternOmnidirectional works as expected.

Hi guys, We're testing our video editing iPad app on an M1 iMac and the export session export process starts but freezes and fails soon after with the following error. Compiler failed with XPC_ERROR_CONNECTION_INTERRUPTED  MTLCompiler: Compilation failed with XPC_ERROR_CONNECTION_INTERRUPTED on 1 try Any ideas on how to resolve this? Thanks! Jed Update: Looks like AVVideoCompositionCoreAnimationTool is causing the issue. When we commented out that line, the export was successful.
