R5VideoViewController.scaleMode controls the display mode of the content that is being pushed to it. Depending on the value the content will scale to the appropriate fill value.
Touch the screen at any time while streaming to rotate the video source by 90 degrees. It's sugested that you verify this change with a separate device.
R5VideoViewController.scaleMode has 3 potential enum values.
r5_scale_to_fill: scale to fill and maintain aspect ratio (cropping will occur)
r5_scale_to_fit: scale to fit inside view (letterboxing will occur)
r5_scale_fill: scale to fill view (will not respect aspect ratio of video)By default, this value is r5_scale_to_fill and the android SDK handles this enum through raw int value (0,1,2) This example cycles through these values when it receives a tap.
@objc func handleSingleTap(recognizer : UITapGestureRecognizer) {
var nextMode = (currentView?.scaleMode.rawValue)! + 1;
if(nextMode == 3){
nextMode = 0;
}
currentView?.scaleMode = r5_scale_mode(nextMode);
}
