AIS and UDI incompatibilities

Description

For ADI, always enabling smoothing while AIS is disabled (AIS : 0, DEFAULT_IS 1), the table g_aucIntraFilter[iIntraSizeIdx][uiDirMode] is used to determine wether reference samples are filtered once 1, twice 2 or not 0.
For UDI with AIS : 0 and DEFAULT_IS 1, reference samples are always filtered once which performs worse than not filtering.

Integrating a similar table for smoothing in UDI would solve this issue.

Dear B. Bross,

I have a question. According to your statement, is it correct to think that after your fix, coding efficiency of "AIS off" will be increased? In that case, I guess the gap between "AIS on" and "AIS off" will be smaller. If you think I am wrong, please shed light on me.

Thanks,

Il-Koo Kim
