Original commit message from CVS: * ext/wavpack/gstwavpackparse.c: (gst_wavpack_parse_src_query), (gst_wavpack_parse_create_src_pad): * ext/wavpack/gstwavpackparse.h: Always report the duration if we know it in push mode and don't return 0 just to make totem believe we can't seek in push mode. Newer totem version use the SEEKING query which properly reports if we can seek or not.
