Package: xserver-xorg-video-intel Version: 2:2.99.917+git20200714-1 Severity: minor File: /usr/lib/x86_64-linux-gnu/libIntelXvMC.so.1.0.0 User: debian...@lists.debian.org Usertags: undefined-symbol adequate
libIntelXvMC.so and libI810XvMC.so need to link with -lXv, see the output of adequate, symtree and objdump below. I detected this on amd64 but I assume it also occurs on other architectures. I filed this bug at severity minor since I'm not sure if there are any programs using the libIntelXvMC.so and libI810XvMC.so libs and if they already use the libXv.so symbols and link with the -lXv flag or not.

Either the binary either needs to be linked with an additional shared library, or the dependency on the shared library package that provides this symbol is too weak.
