(I'm guessing) the package you downloaded isn't really from a well-maintained repository specifically made for CentOS 7. It's not just up to the package manager but also the packager and the packages. If a package doesn't define its dependencies well or if it is old and depends on ancient versions of things that aren't around anymore, it isn't going to work. Use the repo mentioned and you'll most likely be successful. Pick some random rpm and not so much. Regarding libquicktime... what is it you are wanting to do? Encode video, play back video, or what? ffmpeg really is the king of the encoders and vlc or mplayer are the tops of playback mainly because they offer support for so many container formats and codecs.
