Hi Deepali, Thanks for the reply. The scenario described in the FAQ could be true because sometimes (once in 10 times) i'm getting different crash than described previously.

How can I find out which thread calls are causing this problem because my application uses different threads for video encode & decoding , audio encoding & decoding. The backtrace given above is of no help!!!
