Comment (by yawning):

 It looks like the browser people sort of considered the ffmpeg situation
 at #18946, and I initially added the pref in #20806.

 The list of shared objects that FF will pull appears to be hardcoded in
 `dom/media/platforms/ffmpeg/FFmpegRuntimeLinker.cpp`.  When I initially
 wrote this, it was also pulling in libgstreamer (which has explicitly
 always been rejected via the fine grained shared object code), but maybe
 that's gone now.

     "libavcodec-ffmpeg.so.56",
     "libavcodec.so.57",
     "libavcodec.so.56",
     "libavcodec.so.55",
     "libavcodec.so.54",
     "libavcodec.so.53",

     // "libgstreamer-0.10.so.0",
     // "libgstapp-0.10.so.0",
     // "libgstvideo-0.10.so.0",
 }}}
