Releases ----------- 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 - Refine strategy on level change to avoid frequent IDR. Encoder will not be reset if level is changed to a smaller one - 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 - Support to get information about current output picture is reference picture or not on decoder side - Bug fix for decoder when 8x8 prediction mode is enabled on the input bitstream - Enable NEON for ChromeOS devices - Support for Fuchsia operating systerm - Support for building arm64 with MSVC - Remove some warnings when building with MSVC - Fix clang compiler error when building arm assembly funtions - Bug fixes for unit test v1.7.0 ------ - Changed SPS/PPS strategy option name,See enum ENCODER_OPTION - Changed NAL size length parameter from static array to pointer to support more NALs.See struct SParserBsInfo - Changed semaphores to condition variables on apple platform - Changed version update mechanism as Major.Minor.patch,like 1.7.0 - Supported to force IDR independently for each layer in simulcast AVC case.See API ForceIntraFrame() - Supported LTR request independently for each layer in simulcast AVC case.See struct SLTRRecoverRequest and SLTRMarkingFeedback - Supported to set sample aspect ratio in VUI on encoder side.
