Converting YUV into BGR or RGB in OpenCV

Question

I have a TV capture card that has a feed coming in as a YUV format. I\'ve seen other posts here similar to this question and attempted to try every possible method stated, b

Answer 1

The BlackMagic Intensity software return YUVY' format in bmdFormat8BitYUV, so 2 sources pixels are compressed into 4bytes - I don't think openCV's cvtColor can handle this.

You can either do it yourself, or just call the Intensity software ConvertFrame() function

edit: Y U V is normally stored as

There is a Y (brightness) for each pixel but only a U and V (colour) for every alternate pixel in the row.

So if data is an unsigned char pointing to the start of the memory as shown above.

pixel 1, Y = data[0] U = data[+1] V = data[+3]
pixel 2, Y = data[+2] U = data[+1] V = data[+3]

Then use the YUV->RGB coefficients you used in your sample code.
