Reduce buffer in RTSP stream on Android

Is there a way to adjust the amount of buffer in the RTSP playback on Android? I’m using a daily build on a Kindle Fire tablet and streaming video from my HDZero goggles. I’ve noticed that the video in QGroundControl is significantly delayed from realtime. So much that after I have landed and powered down the whole system including my goggles, the video stream is still showing the footage in flight on the tablet.
