Subject: [PATCH] video: Don't corrupt caption GstMeta

the meta initialization function is provided *after* the base implementation
fields have been set so do *NOT* reset them otherwise it would result
in corrupted GstMeta.

Instead explicitely set our fields to the default values we actually want.
