Expand description

Simple angular intra prediction placeholder (modes 2..=34). Uses horizontal or vertical extrapolation depending on mode direction. HEVC angular intra prediction with fractional-sample interpolation.

ITU-T H.265, section 8.4.4.2.6. Modes 2-34 project through reference samples at angles specified by the INTRA_PRED_ANGLE table. Fractional positions use 32-phase linear interpolation.
