Hi,

I am trying to build the CEF branch 4147 (ver 84) with proprietary_codecs=true by using automated method.

set GN_DEFINES=is_official_build=true ffmpeg_branding=Chrome proprietary_codecs=true
py C:\CEF84_Auto\automate-git.py --download-dir=C:\CEF84_Auto --branch=4147

but getting the below error

Try delete everything and do a clean build.
