Element Properties:

  file-path           : Absolute path to input file with ROIs to attach to buffer.
                        flags: readable, writable
                        String. Default: null

  mode                : Mode used to attach ROIs from JSON file
                        flags: readable, writable
                        Enum "GstGVAAttachRoiMode" Default: 0, "in-order"
                          (0): in-order         - Attach ROIs in order. Number of frames in the pipeline must match to number of ROIs in JSON.
                          (1): in-loop          - Attach ROIs in cyclic manner. Same as in-order, but for cases when the number of frames in the pipeline exceeds ROIs in JSON.
                          (2): by-timestamp     - Attach ROIs using timestamping. ROIs in JSON file must be timestamped.

  name                : The name of the object
                        flags: readable, writable
                        String. Default: "gvaattachroi0"

  parent              : The parent of the object
                        flags: readable, writable
                        Object of type "GstObject"

  qos                 : Handle Quality-of-Service events
                        flags: readable, writable
                        Boolean. Default: false

  roi                 : Specifies pixel absolute coordinates of ROI to attach to buffer in form: x_top_left,y_top_left,x_bottom_right,y_bottom_right
                        flags: readable, writable
                        String. Default: null
