Pi2Z, PiHQ Cam --> ERROR [349.260 stream] -- Can't grab device buffer: Resource temporarily unavailable
Im having some issues getting ustreamer working with a Pi2Zero. Ive found that I can't make it work at all without libcamerify, but that does work. It just keeps dropping out for some reason.
Start command I'm running:
libcamerify ustreamer --host :: --encoder=m2m-image
Here is the command line output:

Any thoughts? Seems like the module is working fine. I tried upping the GPU memory to 128 but it still happens.
Thanks.

As far as I can tell, this is a problem on the libcamerify side. For some reason, it can't grab frames from your camera. Please contact Raspberry on their forum regarding libcamera, I think they have a better understanding of how this thing works.
