I can't predict, but given the trend not before the end of the summer.
Currently fixing framework issues has the priority.
Also note that the MPlayer/libmpcodec filters should be ported,
currently there is no sense into writing a wrapper around it. If
you're interested we can assist you into porting some filter from
libmpcodecs, just take one you find interesting and I'll try to review
your patches and answer your questions. Maybe that could be an
occasion for extending the tutorial we have in the multimedia wiki.

Simply you can post patches here or in the FFmpeg soc mailing list.
