Gal, does this library actually work with v4l devices with your patch? V4L1 support was completely removed in the Linux kernel, so merely bringing back the headers through libv4l1-dev won't help much: It will just fail to initialize at runtime.

The proper solution is to use v4l2 only, and the upstream patch seems to do that: https://code.ros.org/trac/opencv/changeset/5206

Can we backport this patch instead?

Update the merge (https://code.launchpad.net/~gal-fourier/ubuntu/natty/opencv/bug-756154/+merge/60312) with a rewrite of the patch that is now derived from upstream changeset https://code.ros.org/trac/opencv/changeset/5206 (see Martin's comment above):

Here is the relevant entry from the debian/changelog:

opencv (2.1.0-3ubuntu2) unstable; urgency=low

* Add patch ubuntu11.04_no_videodev.h_include_file.patch - fix build error on Ubuntu 11.04 Natty (LP: #756154):
- Backport the upstream 2.2 changeset to void the use of the obsolete V4L1 (linux/videodev.h)

Note: Large V4L2-related changes from upstream are NOT included within this bugfix. See also at:
* Upstream (i.e. version 2.2 file) with the V4L2-related changes: https://code.ros.org/trac/opencv/changeset/5206/branches/2.2/opencv/modules/highgui/src/cap_libv4l.cpp
* Affected file (i.e. version 2.1 used by Ubuntu 11.04 Natty): src/highgui/cvcap_libv4l.cpp

Note on testing:
* The new FFmpeg sources from Ubuntu 11.10 Oneiric do NOT compile against the OpenCV package (that is 2.1)
However, testing was OK with:
* Ubuntu 11.04 Natty gcc 4.5
* Ubuntu 11.10 Oneiric gcc 4.6 while using the old Ffmpeg sources from Ubuntu 11.04 Natty

More notes on testing:

After fixing the above bug - we get more build errors of the OpenCV package on Ubuntu 11.10 Oneiric because of:

1. The OpenCV 2.1 version is used
2. The new FFmpeg 0.7 version is used
3. OpenCV version 2.1 do not compile against the new FFmpeg version 0.7

AFAIK, the latest SVN version of OpenCV do not either compile against the new ffmpeg 0.7 and it is likely that the OpenCV developers will have to modify the OpenCV sources to allow a build against the new ffmpeg 0.7.

Verify that latest OpenCV-2.3.0rc.tar.bz2 (released on 2011-06-21) do also have compilation errors when compiled against Ffmpeg0.7 from Ubuntu 11.10 oneiric (OpenCV-2.3.0rc.tar.bz2 is available from http://sourceforge.net/projects/opencvlibrary/)
