Since you have changed the dependencies for libdc1394-13-dev to
libdc1394-22-dev, could you please investigate this issue? I don't know
much about firefire libs, but it seems to me that the version of ffmpeg
we ship is not prepared use the newer version. I'd therefore suggest to
revert the switch to libdc1394-22-dev, but I wanted to give you the
oppurtunity to comment on the issue.
