Enabling USB Video Input?

[tmdarwen]

I'm using an Avermedia ExtremeCap UVC - BU110 device to input video into the Jetson. When using the NVIDIA Jetson Linux image I simply plug the device into a USB 3.0 slot on my Jetson Mate and it will show up as a new video device in /dev and then I can use it to process video input.

This isn't happening with my meta-tegra image. When I plug in the Avermedia device no new devices show up in /dev. I imagine I'm missing some sort of USB UVC Linux driver on my meta-tegra image. Very possibly this. I'm not sure how to get this built into my meta-tegra image though.

I grepped the repos dir of tegra-demo-distro for uvc and only found it mentioned in these four files:

./meta-openembedded/meta-networking/recipes-protocols/freediameter/files/0001-Fix-testcnx-expired-CA-data.patch
./meta-tegra/contrib/recipes-multimedia/gstreamer-1.14/gstreamer1.0-plugins-bad_1.14.4.bb
./poky/meta/recipes-multimedia/gstreamer/gstreamer1.0-plugins-bad_1.16.3.bb
./meta-mender-community/meta-mender-sunxi/recipes-kernel/linux/linux-friendlyarm/defconfig

None of those appear to be what I'm looking for.

Any idea if there's a layer I can add to get this driver in my meta-tegra image?

Just add kernel-module-uvcvideo to your image, or kernel-modules if you want all of the kernel modules (like NVIDIA's Ubuntu does). Typically for an embedded systems build you don't want that, though.

Awesome! Adding kernel-module-uvcvideo worked! Thanks again!
