Original commit message from CVS: * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_register): * ext/ffmpeg/gstffmpegdemux.c: (gst_ffmpegdemux_register): Don't register the WavPack demuxer and decoder. They don't work, we have better ones and the output of the demuxer/input of the decoder is in a different format than what audio/x-wavpack of the wavpack plugin is (it seems that the demuxer strips of the wavpack headers from every frame). This fixes typefinding of Wavpack files again, as the ffmpeg typefinder was preffered for some reason and gave application/x-gst_ff-wv instead of audio/x-wavpack.
