skimage uses avconv for video I/O. Please try installing avconv (and make sure it is in your path).

On Ubuntu: sudo apt-get install libav-tools

On other linux: get from http://johnvansickle.com/libav/ unpack and put in path

ffmpeg may work as well but is untested (change avconv/avprobe to ffmpeg/ffprobe in skvideo/io/initpy source)

Confirmed. Thank you.
