segmentation fault when running tutorial4 or any other after that

[pawan9]

The tutorials are compiling fine but I am getting segmentation fault error when running tutorial4 it or any other tutorials after that.

gdb backtrace

Program received signal SIGSEGV, Segmentation fault.

Is seems like it is related to the sdl library. How do i resolve it.

here is the link to the valgring output(was just playing around with it) (http://pastebin.com/1HFrwP5W) maybe this can help find the problem.

@pawan9 Did you solve the segmentation fault problem? I'm also having the same problem. May I know if you have solved it, thank you.

i got the same problem on mac 10.11

But what amazing: use tutorial04 in this repository, it's ok now!

@houshunwei I tried it long time ago. Try to put the following line in the decode_thread() function.
pFormatCtx = avformat_alloc_context();
