Thank you for your prompt response Greg. I have provided a focused sample project as a link. Please look in the code for the methods in the PreviewViewRenderer, in particular convertYUVToRGB. Basically after the capture receives the sample buffer I feed it in to my swift concurrent environment via a stream and then I start processing frames on the GPU. Thanks in advance for your consideration. Sample Project https://web.tresorit.com/l/YTeHU#Q8JUzXpd2KplKj-trr60-g
