Thank you for report Markus. I don't see any linkage of linphone with v4l libs here. My guess is that you've mixed linphone and mediastreamer linkage. Please check that linphone links with v4l with the following command: readelf -d /usr/bin/linphone | grep NEEDED And in case it really is, then, please, reopen this bug. Currently I think this is duplicate of bug #352713 (Note ldd is bad tool for this since it shows dependencies of dependencies too, use mentioned readelf or lddtree) *** This bug has been marked as a duplicate of bug 352713 ***
