A good idea would be to make a spring cleanup in libquicktime and remove all legacy API stuff in our
libavcodec frontends (and require a more recent ffmpeg version).
Theoretically we still support hopelessly old ffmpeg versions, which probably noone uses anymore and
which mess up our code with lots of #ifdefs.

As alwayws, patches are welcome (I can't work on lqt a the moment).
