Re: [FFmpeg-user] Cannot build ffmpeg 4.1 on Cygwin
Carl, Thanks for your help! I have successfully built a set of shared libraries on Cygwin.

Reindl, Thanks for taking the time to comment. I work in a "sensitive" environment, and am limited to what corporate system administrators are willing to provide. I'm looking into upgrading the Cygwin they provided.

Re: [FFmpeg-user] Cannot build ffmpeg 4.1 on Cygwin
My Cygwin is probably old - the machine I am developing on has version 1.7.17. The "--disable-indev=dshow" flag allowed the build process to get further, but it still fails with multiple errors. Here are the first few...
