Re: [Mingw-w64-public] Issue in x264 - ffmpeg building and usage in different Windows versions

[Shiju S. <sas...@gm...>]

Hi,

Do any of you have pointers on the below errors while I compile my windows
32 DLL using static CRT ? Deployment of the application has issues, when we
have dynamic CRTs. Please guide.

Thanks,
Shiju
