Original commit message from CVS: * ext/vorbis/vorbisdec.c: (vorbis_dec_decode_buffer): Skip empty buffers, but not empty header buffers. That way the original vorbisdec unit test still passes (#451145); also, take into account that those empty packets might carry a granulepos. * tests/check/Makefile.am: * tests/check/elements/vorbisdec.c: (_create_codebook_header_buffer), (_create_audio_buffer), (GST_START_TEST), (vorbisdec_suite): Add unit test that sends an empty packet.
