Real Tags
ExifTool recognizes three basic types of Real audio/video files: 1)
RealMedia (RM, RV and RMVB), 2) RealAudio (RA), and 3) Real Metafile (RAM
and RPM).
These Tag ID's are Chunk ID's used in RealMedia and RealVideo (RM, RV and
RMVB) files.

The tags below represent information which has been observed in the Real
Metadata format, but ExifTool will extract any information it finds in this
format. (As far as I can tell from the referenced documentation, string
values should be plain text, but this is not the case for the only sample
file I have been able to obtain containing this information. These tags
could also be split into separate sub-directories, but this will wait until
I have better documentation or a more complete set of samples.)
