[gentoo-dev] RFC: Remove USE="v4l2" and rename the consumers to plain USE="v4l"?

[Samuli Suominen]

First of all, it's disappointing how little the packages in the
linux-headers-2.6.38 tracker[1] intrest people.

[1] http://bugs.gentoo.org/359595

Planning on masking some of the low hanging fruits from the tracker.

And after the bugs are mostly (or all) dealt with, I suggest we remove
USE="v4l2" and make USE="v4l" mean:

"Enable support for video4linux (with or without userspace library libv4l)"

And rename the pkgs using USE="v4l2" to USE="v4l".  Since there will be
only video4linux version 2, using libv4l or without (or possibly using
libv4l compability layer for libv4l1).   But no more straight up version
1 support since videodev.h is gone since Linux 2.6.38

?

Indeed.  I finally decided to try to get the netbook's webcam running the 
other day.  With kernel 2.6.38's lack of v4l1, it's a serious webcam 
package wasteland out there!  (luvcview, hasciicam... that was about it.) 
=:^(

luvcview demonstrated that it was working, tho, and it was quite apparent 
I had to wait for the 2.6.38 stabilization to take care of the others 
before I tried them.  But /how/ long has this removal been in progress and 
the apps are /still/ dependent on videodev.h?  Disappointing, to say the 
least.  Guess dealing with it's unavoidable, now.

I think for a while people would read "v4l" as "v4l1", as v4l did denote
version 1. Any reason not to congregate everything to USE="v4l2"
instead?
