I worked in window10 with vs 2017 . when compiled CS_WebRTC_Client_SDK_Windows.v4.2  , these error occured below:

1>owt-release.lib(msdkvideobase.obj) : error LNK2001: 无法解析的外部符号 _MFXVideoUSER_Load
1>owt-release.lib(msdkvideobase.obj) : error LNK2001: 无法解析的外部符号 _MFXVideoUSER_UnLoad
1>owt-release.lib(msdkvideobase.obj) : error LNK2001: 无法解析的外部符号 _MFXInitEx
1>owt-release.lib(msdkvideobase.obj) : error LNK2001: 无法解析的外部符号 _MFXVideoCORE_QueryPlatform
1>owt-release.lib(msdkvideobase.obj) : error LNK2001: 无法解析的外部符号 _MFXDoWork

Does anybody helps me to  figure out  the problem ? Thanks

Already fixed it .   The libmfx i compiled has some problem.
