Author: cigaes Date: Wed Oct 12 13:38:10 2011 New Revision: 34190 Log: libmpcodec: add vf_lavfi. This filter wraps a complete libavfilter filter graph. As the API of libavfilter is not completely stable yet, the filter is not enabled by default, so as not to let mplayer unbuildable. Some strange behaviours may appear due to the very different model of buffer allocation between mplayer and lavfi.
