#26 fixed Minor bug fix with VSP code, not affecting CTC tech dong.tian

Thanks to Shinya for spotting the bug. The fix is verified under CTC and no impacts on anchor results.

Line 3560 of TEncSearch.cpp (HTM v6.0) is

motionCompensation( pcCU, pcYuvPred, pcCU->getZorderIdxInCU(), REF_PIC_LIST_1, iPartIdx );

It should be fixed to

motionCompensation( pcCU, pcYuvPred, pcCU->getZorderIdxInCU(), eRefPicList, iPartIdx );


#27 fixed Obsolete IC process in new MPI tech Tomohiro Ikai

Due to JCT3V-C0137 adoption, which changes implicit motion inheritance to explit merge mode, the derivation process anyIvRefPicFlag for depth was obsolete. Specifically, the result of depth's anyIvRefPicFlag derivation is equal to the result of texture's anyIvRefPicFlag derivation.

I talked this part with the original IC proponent and they confirmed this part is obsolete and agreed that this part's removal.

While basically this change is editorial change, HTM also needs to be fixed.

#28 invalid HTM memory problem in 1080p encoding tech Tomohiro Ikai

At new HTM-6.2-dev integration phase, my simulation sometimes failed. I thought this was due to memory usage increase of the integrated version and checked memory usage before and after integration (HTM-6.2 and HTM-6.2-dev). Then i found the following strange behaviour (potential bug) in HTM encoder.

The memory usage of 720p was constant (2.4 G bytes in my environment) while that of 1080p varies from 2.8G bytes to 3.9Gbytes. The memory usage varies by runs!

This strange behavior occcued at leaset in HTM-6.0, HTM-6.2 and HTM-6.2-dev branch2. Please see the attached file.

Attached is my memory usage reports, which is got by qacct -j $job | grep maxvmem

I suppose this "randomly" different memory usage occured "only in 1080p" suggests potential bugs in HTM.
