The GStreamer element is called "rrmotionoverlay". This element performs the drawing of the bounding boxes. The "rrmotionoverlay" receives as input a frame in GRAY8 or RGBA format and outputs a GRAY8 or RGBA frame.
Main Properties
- Color: With this property you can choose the color to use for the bounding box (big-endian ARGB). By default it is 4294967295(hex:FFFFFFFF).
- Draw: With this property when enabled a bounding box will be drawn around each detected blob. By default it is true.
- Thickness: With this property you change the line thickness to use for the bounding box. By default it is 10 and the units are positive integers.
