Setting border and corner attributes for compositing in Amazon Chime SDK meetings

As desired, you can use the VideoAttribute parameter to specify border and corner settings for your video tiles. You can specify colors, widths, and rounded corners. You can also specify a highlight color, and the border changes to that color when someone speaks.

Your attribute settings apply to all layouts, regardless of content sharing.

The following image shows a video tile with a border color and corner radius applied.

The following example shows how to use each attribute. In this case, video tiles have rounded corners with a five-pixel radius. The tiles have a green border, also five pixels wide. When the speaker talks, the HighlightColor attribute changes the border color to red.

{
   "CompositedVideo":{
      "Layout":"GridView",
      "Resolution":"FHD",
      "GridViewConfiguration":{
         "ContentShareLayout":"ActiveSpeakerOnly",
         "ActiveSpeakerOnlyConfiguration":{
            "ActiveSpeakerPosition":"TopRight"
         }
         "VideoAttribute": {
            "CornerRadius"   : 10,                               
            "BorderColor"    : "Green", 
            "HighlightColor" : "Red",  
            "BorderThickness": 5 
          },      
       }
   }
}
