There are two problems:

1. Current code ignores list of layers of an OLS associated with additional layer set when DefaultTargetOutputLayerIdc in layers.cfg is equal to 2.
2. After the modification made in Rev 982, the PTL index may not be assigned to each layer of OLS when DefaultTargetOutputLayerIdc is equal to 2

Patch to fix these problems is attached

Latest SHM-dev cannot pass all HEVC conformance streams. ( ​http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/draft_conformance/)

For example, CIP_A_Panasonic_3, DELTAQP_A_BRCM_4. Segmentation faults were incurred under Linux.

I had verified HM 16.6, which has no such problem.

It seems that the SHVC specification is missing some information to specify the use of inter-layer motion prediction and sample based prediction for SNR scalability. There exists SamplePredEnabledFlag and MotionPredEnabledFlag that is used to control if resampling of the inter-layer reference picture or its motion field is performed when the resolution of the reference picture and the current picture is different but it does not specify anything specific for the case that the resolutions are identical.

It can be resolved by replacing following text in H.8.1.4

– rsPic is set equal to rlPic.

with

rsPic is derived as follows: – The PicOrderCntVal value of rsPic is set equal to the PicOrderCntVal value of rlPic. – When SamplePredEnabledFlag[ currLayerId ][ rLId ] is equal to 1, the rsPic is set equal to rlPic. – When MotionPredEnabledFlag[ currLayerId ][ rLId ] is equal to 1, the motion field of rsPic is set equal to the motion field of rlPic.
