[Ffmpeg-devel] pip.c - PiP (Picture in Picture) v1.0 patch. Remakeof watermark.c

[Mihail Stoyanov]

You can view the PiP in action here (click twice on the FLV Player):
http://vid.data.bg/9x9hlu1r?skip_redir=1&lang=en#vid

The PiP movie is in WMV format, using mode 0, contrast -50, fade in/out and 
so on
See the command line below

Here's the convert output of ffmpeg:
