 Posted: Wed Aug 31, 2011 6:41 am Post subject: Solved: media-video/motion on new kernels without videodev.h |
 |
|
Good news, I solved a problem with media-video/motion (motion detection webcam program). It was broken on new kernels that lack the deprecated videodev.h file. After stumbling around for a while, an easy solution was found, simply use the headers from the "libv4l" userspace compatibility library instead.
This is for motion-3.2.12 (the most current version in the Portage tree that I have).
Here's the patch for changing the motion-3.2.12.ebuild file (apply this by hand):
| Code: |

It adds a patch file. Here is the contents of the patch file, which should be placed in the "files" directory, here: media-video/motion/files/motion-3.2.12-v4l-headers.patch

With these 2 changes, it works, and I'm happily running motion now, under kernel 3.0.3!

Hello,
I am currently running into the same problem that you had with motion.
I have applied your changes to motion-3.2.12-r1.ebuild as well as added your motion-3.2.12-v4l-headers.patch.
Unfortunately, this is what I am getting after updating the digest and emerging with the new ebuild:
| Code: |
Would you like to merge these packages? [Yes/No] y

I am still fairly new to Gentoo (a few months in) and have never edited ebuilds before, so I am not sure if there is something that I am doing wrong, or if the patch is broken. |
