The libraries libavcodec, libavformat, libavutil and libswscale are
part of FFMpeg / libav. Video package uses them for decoding/encoding
video data. The installation has failed as those libraries were not
found in your system.

FFMpeg works in windows (example VLC player uses libavcodec) so the
video package should work too.
