OMX_UseBuffer() is completely useless API, like the USERPTR API in v4l2. You
can pass any type of memory in there but the port can reject it, and you have
no idea what kind of memory the port actually wants.

I also some OpenMAX implementations where no system memory pointer was passed
to OMX_UseBuffer() but handles (think of file descriptors).
