Support YUV420 (8bit) bitstream.

For historical reasons, besides formal HEVC bitstream, it also supports bitstreams generated by older HM encoders (HM-4.0, HM-5.2, HM-10.0 and HM-12.0).

Written in C++ with Qt5 (c++11 support required) You should get and install Qt 5.1.0 or higher.

1. Clone this repository.

git clone https://github.com/lheric/GitlHEVCAnalyzer.git GitlHEVCAnalyzer

2. Init & update the submodules.

cd GitlHEVCAnalyzer
git submodule update --init --recursive
git submodule update --recursive

3a. Build on linux:

qmake -qt=qt5 GitlHEVCAnalyzer.pro -r "CONFIG+=Release"
make

3b. Build on windows:

qmake GitlHEVCAnalyzer.pro -r "CONFIG+=Release"
make

3c. Build on macosx:

# in case you don't have qt5 installed
# brew install qt5
qmake GitlHEVCAnalyzer.pro -r "CONFIG+=Release"
make

Instead of the building on the command line , Qt Creator is supported. Clone this project and its submodules, then open GitlHEVCAnalyzer.pro in Qt Creator.
