Point of Interest. But I realize there is nothing that exist under this
name. Digging further, GST_TAG_APPLICATION_DATA seems very appropriate
if supported by the container you have chosen. Maybe GST_TAG_ATTACHMENT
could also be used (you can specify a filename and content type). There
is a tag called GST_TAG_COMMENT that is often suitable, as long as you
data is a string, otherwise it won't work with standard player.

No, if you seek to location 50, only the serialized tag from that
location will be sent. Again, it requires a container (or encoding like
JPEG) that supports this.
