LibRtmp-Client-for-Android: App crashes (SIGABRT) on fast RTMP stream restart

Issue description

App crashes if RTMP streams are changed quickly (release player/initialize player) using ExoPlayer. If I make a delay before initializing a player with RTMP stream (1000ms) it doesn’t crash. It has something to do with improper thread handling of RTMP extension. It doesn’t happen if non-RTMP streams are used. It also doesn’t happen if you switch between non-RTMP and RTMP streams.

Please suggest a workaround, I can modify the library of ExoPlayer. Thanks.

Reproduction steps

Quickly release/reinitilize player with RTMP streams inside the same activity.
