#GstReferenceTimestampMeta can be used to attach alternative timestamps and
possibly durations to a #GstBuffer. These are generally not according to
the pipeline clock and could be e.g. the NTP timestamp when the media was
captured.
The reference is stored as a #GstCaps in @reference. Examples of valid
references would be "timestamp/x-drivername-stream" for timestamps that are locally
generated by some driver named "drivername" when generating the stream,
e.g. based on a frame counter, or "timestamp/x-ntp, host=pool.ntp.org,
port=123" for timestamps based on a specific NTP server.
