Reading and writing videos via opencv does not work on linux

[sdvillal]

Upstream issue: conda-forge#73

The solution, package v4l and v4l-utils into conda-forge. Do time allowing.

Unfortunately it is not only that it does not work, it does not work silently. So in the meantime, we should add strong checks of this happening (for example, check that a video file is being created).

Apparently the problem was an unfortunate combination of an opencv 3.2.0 issue (fixed in master), building with an old version of gcc (the price to pay when you want stuff to work almost anywhere) and tests that were not running. It probably will get solved when this PR gets merged upstream. I keep this open until the fix makes it to our own packages.

I also think we should cherry pick opencv/opencv@a41d877 On 27 May 2017 19:03, "Santi Villalba" <notifications@github.com> wrote: Apparently the problem was an unfortunate combination of an opencv 3.2.0 issue <opencv/opencv#8097> (fixed in master <opencv/opencv#8561>), building with an old version of gcc (the price to pay when you want stuff to work almost anywhere) and tests that were not running.

Closing this as it is all fixed with our forthcoming new package.
