TIImgenc1 pthread_create permission problems.

It looks like TIimgenc1 uses threads with realtime scheduling (SCHED_FIFO). 

I'm guessing that in more recent kernels, the permissions on creating these became more restrictive.  I'm getting EPERM error from pthread_create() inside gsttiimgenc1.c file.

I tried setting permissions in limits.conf, but I'm still not able to get it to run.

This is a 3.0.22 kernel (angstrom dist).

Any pointers?

Thanks.
