Replacing libmedia.so is unfortunately not enough. The 
USE_PROPRIETARY_CODECS compile-time flag is checked all over the place, even 
in the application layer. See e.g.:
https://chromium.googlesource.com/chromium/src.git/+/master/chrome/common/chrome_content_client.cc#135

(QtWebEngine's equivalent has the same at:
http://code.qt.io/cgit/qt/qtwebengine.git/tree/src/core/content_client_qt.cpp#n253
by the way.)

You'll probably find more if you search all .cc files for the string. So 
either you patch all these usages in the Fedora Chromium package to look up 
the flag from libmedia at runtime, or there is no way around recompiling the 
whole Chromium.
