@MarsSeed After further investigation, the only relevant option in this subject is 'WITH_LIBV4L'. Option 'WITH_V4L' uses only internal code without linking to v4l libraries and can be enabled (or suppressed). Package updated (again).

@MarsSeed Implemented, although I think this is not strictly needed in this case as v4l will not hurt anyone, and reproducible environment is user responsibility when it matters, but it can help to reduce memory footprint of some users.

Thank you for fixing and enhancing this.
One observation: v4l-utils gets automatically linked to when available. I've built this in an environment together with ffmpeg, which pulled in v4l-utils. (I know ffmpeg itself is not needed for this. But life happens, so people don't always build in a totally clean environment.)
I'd like to suggest that you either declare v4l-utils in depends, or disable linking to it in cmake's configuration (
WITH_V4L='OFF'
andWITH_LIBV4L='OFF'
). Just to ensure a more robust and reproducible build.Thank you in advance for considering this suggestion.

And python2-numpy is also not really needed and not mandatory, I believe.

Based on AUR/opencv2 PKGBUILD, I've found out that
eigen2
is not mandatory: this can be built without it. (The latter AUR package is broken.)bsutherland333 commented on 2022-12-31 01:46 (UTC)
I found that this package will not compile with the latest versions of tbb and ffmpeg, but if you replace those with tbb2020 and ffmpeg4.4 it will.

Sorry lads, I'm at the Polish Ukraine border helping allocate refugees. Expect no update until this hell is over, wish us luck. Have no time nor access to my rig and AUR keys to test/post updates. If you have a patch, ping me on email - I'll add you as co-maintainer. Posted with my old script - https://github.com/bartoszek/aur-post

I can confirm what Thenujan is getting with the
I see this from 2019. It doesn't help me but maybe someone: bug from 2019 inline link.
I've tried adding those flags and following some of those hints linked in the # github issues there and the # stackovereflow link there too but couldn't didn't help.
