Sebastian Dröge 2169215a12 gst/mxf/mxfmetadata.*: If resolving a metadata object failed the first time return 
Original commit message from CVS:
* gst/mxf/mxfmetadata.c: (mxf_metadata_base_resolve):
* gst/mxf/mxfmetadata.h:
If resolving a metadata object failed the first time return
FALSE for a second mxf_metadata_base_resolve() call instead
of TRUE.
