From my point of view, the following needs to be done:

    1) Drop ffmpeg-no-pkgconfig.patch
        Using the system libraries from ffmpeg together with the
        headers of a patched and more up2date ffmpeg-mt will always
        result in trouble.

    2) Link against the ffmpeg libraries, do not dlopen() them.
        This will make shlibs work against and makes it possible to
        binNMU chromium-browser in case of an ABI break in ffmpeg.
