PATCH 1/3 v4l-utils: a new recipe

From: Nitin A Kamble <[email protected]>

The v4l-utils recipe provides v4l2-ctl and other tools, which help in understanding the configuration needed by v4l2 devices like a camera.

This recipe is imported from meta-oe layer, and then updated and modified to work with the newest version.

Thanks for the feedback Otavio. I need it for the encoding support. So I will move it in a separate commit instead.

I was expecting to see PACKAGECONFIG somewhere, is v4l2 autodetected?

There are PACKAGECONFIG definitions for v4l in meta/recipes-multimedia/gstreamer/gstreamer1.0-plugins-good.inc & meta/recipes-multimedia/gstreamer/gst-plugins-good_0.10.31.bb in oecore, which controls building of the v4l2 plugin. And I see it is built even when v4l is not listed in PACKAGECONFIG var, so looks like it is autodetected.

But the above change is to make sure that the v4l2 plugins gets pulled in the image.

Why not keep v4l2-utils in meta-multimedia?

Because of the general availability of accelerated encoding in processors, many BSPs can include the accelerated encoding support. Also because the gstreamers plugin for v4l2 is in oecore, so oecore will be ideal location for v4l-utils.

Thanks,
Nitin

cover RFC: few commits for a new machine feature: v4l2

From: Nitin A Kamble <[email protected]>

Here are few commits to add a new machine feature, v4l2. These commits provide:

* A new recipe which provides tools to poke v4l2 config on the target
* a new machine feature: v4l2 which brings a set of related packages.
* modification to gst-meta-base recipe, to enable the v4l2 gstreamer plugins, when the v4l2 machine features is enabled.

With this, one can easily enable a v4l2 video device on any BSP. This v4l2 support will also be used by the upcoming hardware accelerated encoding support for BSPs.

I am sending these commits as "Request for comments" for now, but I also see that these are complete enough to pull in the oecore layer.

Thanks,
Nitin
