- GstAnalyticRelationMeta is a base class for analytics meta. It's able to store analytics results (GstAnalyticRelatableMtd) and describe the relation between each analysis results. - GstAnalysisRelationMeta also contain an algorithm able to explore analysis results relation using a bfs. - Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix that allow to quickly identify if two analysis results are related and by which relation they related. It also work for indirect relation and can provide the path of analysis results by which two analysis results are related. - One allocation per buffer to store analysis results. Here we rely on the application to guess how much space will be required to store all analysis results. This is something that could be improved significantly but it's a starting point. - Define common analysis results, classification, object-detection, tracking that are subclass of GstAnalyticRelatableMtd. The also provide exemple of how to extend GstAnalyticRelatableMtd to have them benefit for the mechanim to express relation with other analysis results.
