v1.8.0
------
- Add meson build for Linux/Windows platform
- Disable background detection for screen route
- Add a workaround for Visual Studio 2013 C++ x64 compiler bug on AVX2. That bug will cause crash and has been fixed in Visual Studio 2014
- Change the default profile from baseline to high if user does not set it and CABAC is specified
- Skip frames that are marked as IDR due to scene change and simultaneously marked as skip frame to reduce bit rate
- Refine threshold calculation algorithms for rate control in lower frame rate to get better effect
- Encoder return with a specific return value instead of uninitialize encoder when input resolution is invalid

- Support to set the min and max QP values on screen content mode
- Fix a memory issue that may cause encoder crash when temporal layer change
- Corrected some statistics information
- Refine error concealment algorithms to improve user experience
