This configuration uses a standard RTMP streaming server with the HD plugin to switch video quality. When entering fullscreen mode, the HD video is automatically selected if the user was still in SD mode. Here is the setup:
The streamer server and standard definition video file are specified using the player’s built-in streamer and file configuration parameters per usual. Next, we specify the high definition video using the plugin's hd.file configuration parameter and enable fullscreen high definition switching setting hd.fullscreen to true.
