I try get metadata from Low Latency Stream. Try add DataEventListener to WZPlayerView. But I get:
NullPointerException: Attempt to invoke virtual method ‘boolean java.util.HashMap.containsKey(java.lang.Object)’ on a null object reference
at com.wowza.gocoder.sdk.api.player.WZPlayerView.registerDataEventListener(WZPlayerView.java:1338)
I need to get data that showing on LOG:
06-05 08:39:46.430 27368-27435 D/WMSTransport: Function call request received: onTextData() wth the following parameters:
06-05 08:39:46.431 27368-27435 D/WMSTransport: [00]: “onTextData”,
[01]: {“Key1”: “Val1”,
“Key2”: “Val2”,
“Key3”: “Val3”,
“Key4”: “Val4”,
“Key5”: “Val5”,
“Key6”: 10,
“Key7”: 65536}
Invoking registered function handler onCall() for function onTextData()
Can you help me, or get some simple for getting this data.
