Comment 12 for bug 1365497

@Renato: Thanks for the links, that'll be useful for a proper implementation. However, as I noted above, there is nothing underneath in the backend that will properly raise the error signal. In the meantime, I think we could do a simple implementation in qtubuntu-media based on the file extension that raises an error or not depending on if we support that container (and assumed common codec type(s)) in the container. After I finish up the video freeze/framerate bug and fix the video recording orientation bugs, I can assess working out a time table for a proper solution for this bug.
