Memory consumption too high while applying asset transform on sourceImage

[VarinderSH]

First of all Thanks to the MetalPetal team, I have build an application using this awesome library.
but while testing the application I have found one memory crash which related to asset transform.

I am using MTIVideoComposition to get every frame of the video to process
in this block I am applying multiple filters on the video.
the composition I am using has max 20 video tracks
While testing I found that whenever I am applying transform on the source image as per the video the memory is getting too hight and at the end memory crash is occurring.

I have found this method to apply transform on the source image

extension MTIImage { public func applyingAssetTrackTransform(_ transform: CGAffineTransform) -> MTIImage { let transformFilter = MTITransformFilter() transformFilter.inputImage = self var transform = transform transform.tx = 0 transform.ty = 0 transformFilter.transform = CATransform3DMakeAffineTransform(transform.inverted()) transformFilter.viewport = transformFilter.minimumEnclosingViewport return transformFilter.outputImage! } }

this is the code I am using to render every frame of the video and applying transform
let videoComposition = MTIVideoComposition(asset: composition,
context: renderContext,
queue: DispatchQueue.main, filter: { [weak self] request in
guard let self else { return MTIImage.black }

         var sourceImage = request.anySourceImage.applyingAssetTrackTransform(transform) ?? .black
        return sourceImage

})

Kindly help me to fix this.
