I tried to run this command, and got error

If I change io-mode to mmap or dmabuf, it work perfect.
I noticed most examples use dmabuf-import with the TIovx GStreamer plugin - is there any real performance difference compared to plain dmabuf? Also, why can't I get dmabuf-import to work? Could this be a driver issue on my end?
