GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. refactor YUV to RGB conversions to take color matrix parameter
2. implement J420 and I420 using new function.  Y420

What is the expected output? 
All conversions that support bt.601 to rgb support jpeg ot bt709 color space.

What do you see instead?
J420ToARGB is only conversion.

Please use labels and text to provide additional information.
Reimplement low level YUVTORGB macro via register for row_win.cc
Port to row_gcc.cc
Port to Neon.
Move matrix to common code.
Reimplement C code via matrix and ensure exact same math.
Implement helper function to convert float matrix to SIMD color matrix.
