streaming video metadata

[Stirling Westrup]

My experience with Metadata is that the metadata setter and the metadata
getter need to be in the same shared library, or it doesn't work. So, when
making custom metadata, write a metadata library, and dynamically link both
your reading element and writing element to that library.

Otherwise you often get two copies of the library, and what one knows the
other can't find out.
