[x264-devel] motion vectors and threads

[Christian Bienia]

Hi,

I think I might not have been entirely clear about one of my two questions. 
Please let me explain what confuses me a little more:

The point is that motion compensation needs the image data of the reference 
frame. This, however, is an input which is available at program start. Why 
the need to wait for the encoding output of the reference frame?
