Phonon can read .avi files on MacOS?

I try to read a .avi file on MacOS X with Phonon and Qt. But I can't. Even in QtDemo, the "Media Player" is not able to display those kind of file. Is there a way t开发者_C百科o make it work ?

Try installing the right codecs to the system. "avi" is actually just a container file format that can contain media encoded with many possible audio and video codecs, that might not be supported/installed by default in OS-X. Phonon itself doesn't provide media decoding capabilities, it uses whatever is available on the system or separately configured as it's back end.
