Then your question is best directed at an Apple forum or support channel where 
someone can help you understand the Core Video API.

https://developer.apple.com/documentation/corevideo/1456851-cvpixelbuffergetpixelformattype says "A four-character code OSType identifier 
for the pixel format."

846624121 = 0x32767579 = '2vuy' (see https://onlinegdb.com/HJQVf0U48)

So I assume the pixel format is YUV2.
