Mail sent to all contributors on 2011-09-30:
Hi everybody,
Sakari made me realize today that the media-ctl project is still licensed
under the GPL v2+ license, while I would have sworn that we had switched to
LGPL a long time ago.
I would like to relicense the media-ctl project under the LGPL v2.1+, to allow
LGPL-compatible applications and libraries (such as libv4l for instance, or
its plugins) to link to libmediactl and libv4l2subdev.
As you all have submitted patches that are now included in the media-ctl
project, I'm requesting your permission to proceed with the license change.

Hi Laurent,
No problem for me. You can go ahead, if everyone else agrees of course.
Regards,
Sergio

I'm in favour of the change, actually I think it's next to mandatory for the
library to be useful in a way it was intended.
Cheers,

Changing the license is fine with me.

I have no objections.
But I didn't remember libudev exact license... Ah, okay, it's licensed
under LGPLv2.1+.

Remove extra verbosity by default; "-v" option brings back what used to be
there. The error messages are now being printed by main.c with the possibly
helpful error code attached.

Add debugging handler to media_device that may be used to redirect all debug
formatting to user-supplied function. fprintf will do, and that's what
media-ctl test program will use.

This makes format parsing a part of the libv4l2subdev and thus available on
all who use the library.

This makes it possible to benefit from the link parsing code anywhere the
library is being used.
dprintf macro will later be replaced with proper debug support.
Also fix a case where -1 was returned on error and the user was expected to
check the value of errno. Negative error codes are now returned
consistently.

The code snippet
x = malloc(sizeof(*x));
memset(x, 0, sizeof(*x));
could be easily changed to
x = calloc(1, sizeof(*x));

If configured with --with-libudev, the libmediactl is built with libudev
support. It allows to get the device name in right way in the modern linux
systems.
