Short answer is no.

The question is what mechanism do OMX offer to import or export a
DMABuf. Searching through Khronos documentation, I could not find any
thing. I believe Google OMX might support ION, which indirectly can
wrap a DMABuf. But gst-omx would need some work to support Google OMX.

There could also be something looked up through EGLImage, but I'm not
convinced by the method used for the RPi OMX stack.
