Image Overlay (Watermark)


Can I add a text caption, border or image overlay in the Red5 Pro video stream?


Yes, this is totally possible with our SDK. We do not support this out of the box, but you can add a UIlabel or something else over the R5VideoViewController.view.frame. You would implement this in a subscriber app (take a look at our iOS example or Android example).

For server side implementation, please see our server example.  This particular example gets the number of live streams but you can modify it to send an image.
