Android lollipop 5.1 Streaming play screen stopped

I develops the product using Android 5.1 lollipop, and currently experiencing issues while running the Wowza GoCoder SDK Example.

[ Android 5.1 lollipop board ]

OK : board -> Streaming record > Server.

NG : Server -> Streaming(board) play stopped after one or two frame shown.

When NG status is entering [ Play a live stream ] in menu, and press play icon

then some screen shown and stopped.

but log try to every frame to something. I attached.

Hello @HyunSoo Lee, for playback, Android 6.0 (API level 23) is required.
