CVPixelBuffer.h defines
kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange = '420v', /* Bi-Planar Component Y'CbCr 8-bit 4:2:0, video-range (luma=[16,235] chroma=[16,240]). baseAddr points to a big-endian CVPlanarPixelBufferInfo_YCbCrBiPlanar struct */
kCVPixelFormatType_420YpCbCr10BiPlanarVideoRange = 'x420', /* 2 plane YCbCr10 4:2:0, each 10 bits in the MSBs of 16bits, video-range (luma=[64,940] chroma=[64,960]) */
But when I set above format camera output, and I find the output pixelbuffer's value is exceed the range.I can see [0 -255] for 420YpCbCr8BiPlanarVideoRange and
[0,1023] for 420YpCbCr10BiPlanarVideoRange
Is it a bug or something wrong of the output?If it is not how can I choose the correct matrix transfer the yuv data to rgb?
