[FFmpeg-user] Live preview video editing

My first thought would be to extract a few frames previous to
encoding, then display those, but that may not be what you want.  If
you have to stream it to an rtsp server, then I believe you can use
libavfilter to "split" the stream, and send one (with low frame rate)
to the preview, and the other straight in.

And why does everybody keep calling me Mr. Roger's (just
kidding...though I will admit I watched his show as a child--and
wondered why he kept taking his shoes off when he came in...)
