Hello,
I suspect there is a memory leak bug in
Intel IPP libraries in Linux.
What I did is:
Download ipp41 evaluation for linux.
Download and build the g729 samples for linux.
Ran the sample with a very known memory checker (valgrind) like thus:
valgrind ./g729iencoder --leak-check=yes --show-reachable=yes in.snd decoded.out
==8732== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 4 from 1)
==8732== malloc/free: in use at exit: 5065 bytes in 12 blocks.
==8732== malloc/free: 20 allocs, 8 frees, 40752 bytes allocated.
What seems to me is that 2065 bytes were not freed ,
and it seems that there is some bug as something is not freed inside Intel IPP library. (It could be also
that something is not freed in Intel g729 sample code ,but this seems less likely to me).
Note that is says that there were 20 allocs but only 8 frees !
I want to emphasize that I did not change a thing in
Intel g729 samples and build the using the script
supplied with them (build.sh).
This prevents me from using the Intel IPP for
an IVR server which runs in heavy loads , performing
many calls to g729 encode, because after a time
(depending on the load) we're out of memory and the systems hangs.
Regards,
Rami
