Every time I rebuild it I see: >>> Messages generated by process 12502 on 2015-02-03 01:50:22 CET for package media-video/mjpegtools-2.1.0-r2: WARN: pretend Current versions of mjpegtools only support V4L1 which is not available for kernel versions 2.6.38 and above. V4L1 will be disabled. But we are not providing kernels older that 2.6.38 for a long time, maybe would be better to simply drop the USE flag and disable v4l1 support always Thanks
+ 22 Feb 2015; Daniel Pielmeier <billie@gentoo.org> mjpegtools-2.1.0-r2.ebuild: + Unconditionally disable v4l1 support as kernels providing it are long gone + from the tree. This fixes bug #538626. Thanks to Pacho Ramos for the report. Okay you have convinced me. First I thought it should stay a bit longer as although the kernel sources are gone there might still be some in use out there.
Thanks!
