--- Comment #1 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
If the dmabuf are not mapable to CPU, I don't think it's worth adding a new
format. When I added NV12_64Z32, the dmabufs were all mappable (CMA). Exposing
the format was a great way to help with testing, as I could then use
videoconvert and videotestsrc to produce data that I could just copy into those
DMA buffers. On Exynos 4412, this format came back in many IP blocks, so it was
very useful to test each blocks seperatly.

So question is, is this format mapable ? Would having videotestsrc or
videoconvert support for this format useful ?

I was thinking that we should expose something like:

  video/x-raw-opaque(memory:DMABuf),format=XYZ

In some cases.
