[Libav-user] ffmpeg threading

[Ierum Shanaya]

Hi,

I am trying to run ffmpeg video decoding by creating multiple threads. The
problem i am facing is that only one thread is created, irrespective of
setting the thread_count to 0 or any no like say 2 , 4 etc.

I did check the config as below:

*it doesnt have --enable pthreads things.. Is this the issue??. *
If so, how to set the --enable pthread again in ffmpeg?? Can someone please
help me understand.

I have Ubuntu 12.4 on my system(64 bit)

*Output:*
