edgetpu-demo.bb does not work

[mirzak]

@mirzak how were you able to test the edgetpu-demo.bb file (specifically how were you able to run the resulting file on the coral)? I've included it in a build by adding IMAGE_INSTALL_append += " edgetpu-demo" to local.conf and it builds successfully and is in the image.

However, trying to run edgeput_demo --stream or edgetpu_demo --device initially results in ValueError: Namespace Gtk not available. Adding gtk+3 to edgetpu-demo.bb RDEPENDS_${PN} solves that issue.

Unfortunately, it then fails with Gtk-WARNING **: <time>: cannot open display, which I have not been able to resolve that. I see terminal output on the HDMI but no WM/DE.

I created a new issue for this topic,

I test this using the following image definition

DESCRIPTION = "A console-only image that includes Edge TPU libraries, \
demo applications, gstreamer packages and Freescale's multimedia packages \
(VPU and GPU) when available for the specific machine."

LICENSE = "MIT"

require recipes-fsl/images/fsl-image-multimedia-full.bb

CORE_IMAGE_EXTRA_INSTALL += "\
    edgetpu-demo \
"

Though there is still some problems with this recipe as it requires gobject introspection on gstreamer libraries, but this is disabled.

Let me have a second look at this
