Native crash in FFmpegFrameRecorder.recordSamples() when using RTMPS connection

I'm using this lib to decode sound from microphone to aac and stream it through RTMP(S) to a server. For this I'm using FFmpegFrameRecorder.recordSamples() function and it is working fine when I'm connecting through a normal RTMP connection. But when I'm using RTMPS, it also works fine for the initial 2-3 seconds (and I can playback this little part on the server) but after that the native part just crashes with a not very verbose message:

E/audit: type=1701 msg=audit(1461335772.791:1017): auid=4294967295 uid=10325 gid=10325 ses=4294967295 subj=u:r:untrusted_app:s0:c512,c768 pid=23492 comm="pool-4-thread-1" reason="memory violation" sig=11

When debugging I found that this happens a few seconds after initiating the connection precisely when returning from the recordSamples() function. (initially I thought that the last line was crashing but I modified it and it still crashed when it returned from this function).

Since the crash message is not very verbose and the said function is over a 100 lines with quite a few native calls, I don't really know how to debug this issue. Any ideas?
