source property
The local absolute path of the custom background image. Supports PNG, JPG, MP4, AVI, MKV, and FLV formats. If the path is invalid, the SDK will use either the original background image or the solid color image specified by color. This parameter takes effect only when the type of the custom background image is backgroundImg or backgroundVideo.
