YUV420 to RGB color conversion Error

Question

I am converting an image in YUV420 format to RGB image in opencv but im getting an Orange colored image after

Answer 1

the 1st problem is using the outdated c-api (it's dead & gone. please use c++ instead).

the 2nd problem is writing your own (slow and error prone) pixel loops

why not use :

cvtColor(crs,dst, CV_YUV2BGR); // or CV_YUV2BGR_I420

instead ?
