#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.

#40 fixed Wrong layer_id in decoded picture hash SEI (decoded picture hash doesn't work) tech Tomohiro Ikai

The decoder picture hash doesn't work in enhancement layer.

This is because encoder always send the decoded picture hash SEI with nal_layer_id equal to 0. The decoder decodes the SEI in enhancement layer but interprets that is associated with base layer.

A patch is attached.

#44 fixed Missing of splitFlag definition for DoNBDV and VSP tech Tomohiro Ikai

The process "H.8.5.4 Derivation process for disparity vectors" uses splitFlag. But the input definition of splitFlag seems missing and DoNBDV and VSP process doesn't set the value of splitFlag on calling H.8.5.4.

Fixed WD is attached(same change as WD of JCT3V-E0207).
