Hello everyone, It's not possible to build Qt Multimedia 6.7.2 with GStreamer but with no V4L. Reproducible: Always Steps to Reproduce: USE="gstreamer -v4l" emerge =dev-qt/qtmultimedia-6.7.2 Actual Results: Build fails due to undefined references to QGstreamerCustomCamera. Expected Results: dev-qt/qtmultimedia-6.7.2 has been built and installed. The bug was introduced in https://code.qt.io/cgit/qt/qtmultimedia.git/commit/?id=19dad4ec5 (cherry picked from https://code.qt.io/cgit/qt/qtmultimedia.git/commit/?id=f865bbd6)
Please emerge --sync, v4l already been forced as a workaround in [1]. I'll leave this open until properly resolved though. [1] https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=ea66dd695e44
Also been debating whether it's worth being optional at all given this has no extra dependencies beside linux-headers and is trivial to build (doesn't use libv4l). Albeit non-linux prefixes could be a concern.
