From the logs attached here, I observe the following prints:

Line no. 4060: F/libc    ( 1203): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)

which means your code has crashed. Further down in the log,

Line no. 4084: I/DEBUG   (   83): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000000

From the stack trace of your crash log,

I/DEBUG   (   83):          #00  pc 0000db2c  /system/lib/libc.so (memcpy)
I/DEBUG   (   83):          #01  pc 000710ec  /system/lib/libCedarX.so (rtsp_demux_read)
I/DEBUG   (   83):          #02  pc 000636dc  /system/lib/libCedarX.so
I/DEBUG   (   83):          #03  pc 00012be4  /system/lib/libc.so (__thread_entry)
I/DEBUG   (   83):          #04  pc 00012738  /system/lib/libc.so (pthread_create)

Conclusion:

From these points, I conclude that in rtsp_demux_read function, there is a memcpy call. When your program has crashed, you have passed a NULL pointer as mostly the destination to the memcpy function. You would require to debug your code further on why this could happen.
