Right, the demuxers and muxer can be used without having the library
installed. An #if CONFIG_LIBCODEC2 with a fallback to a fake version
should work. Given that 1.2.0 is the latest release that seems a
reasonable version to signal, indicating "1.2.0 was the last time we
checked that we're compatible with libcodec2"..
