Planar and DC mode in reference software

Question

I am walking through the intra prediction part of HEVC reference software. I can see inter prediction and intra prediction in xCompressCU method in TEncCu.cpp file. But I can't locate the place of planar and DC modes are calculated. Where are these modes in the reference software? Can someone help me with this?

Answer 1

For the DC and all the angular modes, go find the function xPredIntraAng in the TComPrediction.cpp file. These intra modes are performed there.

For the planar, there is another function probably called xPredIntraPlanar. I'm not sure about the name, though. I don't have access to code right now. But if you find the first function, this one must be next to it in the TComPrediction.cpp file.

Good luck.
