 Summary of the bug:
 Some dependent libraries are missing in the package config

 How to reproduce:
 Build ffmpeg with the following script

 {{{
 cd /home/user/ffmpeg_sources
 wget http://ffmpeg.org/releases/ffmpeg-3.2.2.tar.bz2
 tar xjvf ffmpeg-3.2.2.tar.bz2
 cd ffmpeg-3.2.2

 PATH="/home/user/ffmpeg_32/bin:$PATH"
 PKG_CONFIG_PATH="/home/user/ffmpeg_32/lib/pkgconfig" ./configure \
   --prefix="/home/user/ffmpeg_32" \
   --pkg-config-flags="--static" \
   --extra-cflags="-I/home/user/ffmpeg_32/include" \
   --extra-ldflags="-L/home/user/ffmpeg_32/lib" \
   --bindir="/home/user/ffmpeg_32/bin" \
   --enable-gpl \
   --enable-libass \
   --enable-libfdk-aac \
   --enable-libfreetype \
   --enable-libmp3lame \
   --enable-libopus \
   --enable-libtheora \
   --enable-libvorbis \
   --enable-libvpx \
   --enable-libx264 \
   --enable-libx265 \
   --enable-nonfree
 PATH="/home/user/ffmpeg_32/bin:$PATH" make
 make install

 }}}

 This results in the following line in libavutil.pc

 {{{
 Libs: -L${libdir}  -lavutil -lm
 }}}


 When linking programs that use ffmpeg, libavutil fails with

 }}}

 To work around the issue, revise libavutil.pc to have the following line:

 {{{
 Libs: -L${libdir}  -lavutil -lm -lX11 -lvdpau -lva-drm -lva-x11 -lva
 }}}

 This issue appears to have been introduced in version 3.1
