source: SHVCSoftware/branches/SHM-dev/source/Lib/TLibCommon/TComPic.cpp @ 1497

Last change on this file since 1497 was 1487, checked in by fujitsu, 9 years ago

Added support of scalable range extension profiles. Also corrected few issues such as the confWindow wrong initialization. Code is controlled by the macro SCALABLE_REXT.
