[Comment 1 Dennis Schridde 2021-04-15 18:58:56 UTC]

Builds successfully with opencv-4.5.1.

[Comment 2 Paul Gover 2021-04-22 07:46:49 UTC]

I'm seeing the same problems with media-libs/mlt-6.26.1; I have media-libs/opencv-4.5.0, which turns out to be from having mlt keyworded but not opencv.
(I think this mongrel comes out of kdenlive keyworded, but I don't remember.)

Keywording opencv as well cures the build problem.
