parcat - Concatenation tool for parallel simulations ==================================================== This tool allows to cat segments from parallel simulation according to JVET-B0036 into bitstream bitexact with corresponding output of sequential simulation. What it does ------------ This tool - removes any duplicated and unnesessary information from segments like SPS, PPS, VPS, IDR-frames, SEI from all segmetns but first. - adjust POC value to provide continious numbering and correct referencing (actual POC modification occurs only for second and folowing segments) - cat filtered segments into single file Output of this tool is decodable JEM bitstream. Usage ----- ``` parcat [ ... ] ``` where `` is result of parallel simulation according to JVET-B0036. Building -------- The tool is quite simple and is stored in one C++ file. You can build it using any decent C++98 compiler using command line. Alternatevily cmake build system scripts are provided to maintain cross platform experience and simplify generation of IDE-s projects like Visual Studio. To use it - install cmake from [cmake.org](http://cmake.org) - create build folder inside project root folder (where CMakeLists.txt is located) - cd to this folder - configure project using following command line `cmake ..` - build project using your platform's default build system, say Visual Studio on Windows and make on UNIX Restrictions ------------ parcat currently supports only JEM-2.0 and JEM-3.0 bitstreams. Support for HM 16.9 bitstreams is scheduled.
