Bug#793085: ffmpeg: removal of ffmpeg makes files disappear from libav-tools

This should ensure a comprehensive transition. Feedback on these two commits are welcome. In particular, I saw a comment suggesting to transition command-line interface separately from the library interfaces. While this may make the transition slightly smaller, the benefits don't outweigh the confusion here, and would rather suggest to transition them both at the same time with the 2nd commit mentioned above. As I understood it from the transition bug, the commandline-tools transition would be phasing out the libav-tools compat package and switching the users of it (back) to ffmpeg, and that can happen independently and later.

So that's not a 'must' and thus not a release critical bug. Well, that was actually the purpose, the idea is to replace qt-faststart from libav-tools, and the problem is rather transitional until libav-tools is uninstalled. I guess the bug is that we don't ensure that this actually takes place. I've therefore made two commits in git: - one that tightens the Breaks relationship as suggested That one fixes this bug, so I'm setting the pending tag. - one that renames libav-tools-links to libav-tools in src:ffmpeg. That's fine for me if you prefer it that way. I just pushed a commit renaming d/libav-tools-links.links to d/libav-tools.links, so that the links don't get lost. This should ensure a comprehensive transition. Feedback on these two commits are welcome. In particular, I saw a comment suggesting to transition command-line interface separately from the library interfaces. While this may make the transition slightly smaller, the benefits don't outweigh the confusion here, and would rather suggest to transition them both at the same time with the 2nd commit mentioned above. The library transition is already happening, so changing that now is fine.
