GstAnalyticsTextMtd

This type of metadata stores UTF-8 text and its confidence level. It can be used for image/video-to-text and audio-to-text inference.

GstAnalyticsTextMtd only stores text-related information. Additional information such as a bounding box can be represented by other metadata types such as GstAnalyticsODMtd and associated with the text metadata using GstAnalyticsRelationMeta.
