Hi Buga,
The DVSDK does not support the ELF format. I'd suggest you upgrade to a newer SDK. I googled around and found this: http://www.ti.com/tool/linuxsdk-omapl138. The MCSDK appears to be the newest one available. You should be able to use as a new starting point. Maybe others from the SDK team could give you better pointers.
If the newer SDK does not contain codec engine, you can download the latest version from here:

Hope this helps,
Vincent
