Patch remux.c.patch (https://bugs.gentoo.org/attachment.cgi?id=540700) NEEDS REVIEW. I didn't write C code for a long time, so I'm not entirely sure that this is right coding. Compiles fine, though. :-)
mark, what about the media-video/vdr-2.2.0-r3 Version? gcc-7 compile should be fixed there. https://bugs.gentoo.org/show_bug.cgi?id=638348 it is not possible to edit the stable marked version or apply some patches, so please test always with the latest version.
gcc-7 issues are all fixed now in media-video/vdr-2.2.0_r3 please upgrade to the latest version
