Hi,
Hi Hans,
So judging from the directory layout, this is supposed to be a separate
project, and not part of v4l-utils / libv4l, right?
It is separate now, but I guess that at some point it would be good to have
'plugins' directory containing some generic plugins as part of libv4l.

WRT my merging plans for libv4l. I've recently done some much needed
work to better support high-res usb cameras. I plan to do a 0.8.4 release
with that work included real soon. Once that is done I'll change the
version
in the Make.rules to 0.9.0-test and merge the plugin. Then we'll have
some 0.9.x releases followed by some 0.9.9x release (all testing
releases)
followed by a 0.10.0 which should be the first stable release with plugin
support.
Regards,
Hans

Hi,
This is the Media Controller plugin for libv4l. It uses libv4l2
plugin support
which is accepted by Hans De Goede, but not yet included in mainline
libv4l2:
http://www.spinics.net/lists/linux-media/msg32017.html
The plugin allows a traditional v4l2 applications to work with Media
Controller
framework. The plugin is loaded when application opens /dev/video0
and it
configures the media controller and then all ioctl's by the
applicatin are
handled by the plugin.
The plugin implements init, close and ioctl callbacks. The init callback
checks it's input file descriptor and if it coresponds to
/dev/video0, then
the media controller is initialized and appropriate pipeline is created.
The close callback deinitializes the pipeline, and closes the media
device.
The ioctl callback is responsible to handle ioctl calls from
application by
using the media controller pipeline.
The plugin uses media-ctl library for media controller operations:
http://git.ideasonboard.org/?p=media-ctl.git;a=summary
The plugin is divided in three separate patches:
* Media Controller pipelines initialization, configuration and
destruction
* v4l operations - uses some functionality from the first one
* Plugin interface operations (init, close and ioctl) - uses
functionality
from first two

Add files for media controller pipelines
Add files for v4l operations
Add libv4l2 media controller plugin interface files
