please file an issue, there were some work done with removing ffmpeg code from electron. It seems to break. cc @marc-dumais

Hi @big-boy . @anton-kosyakov is right - this build failure is a side-effect of a recent patch where we replace libffmpeg delivered with Electron. We are working on a follow-up patch that removes this side-effect. In the meantime you can work-around the failure by setting an environment variable before building: THEIA_ELECTRON_SKIP_REPLACE_FFMPEG=1

Thank you @anton-kosyakov . I marked an issue.

@marc-dumais thanks, I set an environment, the errors gone.
