Dear @gitdevmod what is the question? I can only see a log dump. For us, Windows 10 building works.

gitdevmod commented 3 years ago

@bk138 I see in your log Visual Studio, I'm using mingw and it fails because SIGQUIT is not declared

Try disabling FFMPEG when setting CMAKE flags.

bk138 commented 3 years ago

But anyhow, your patch seems OK! Do you want to file a pull request?

gitdevmod commented 3 years ago

Ok cool, I'll do a PR
