[vlc] Re: analyzing a video stream

[Bradley, Todd]

Thanks.  openRTSP definitely looks interesting.  But I
didn't see any reference to basic information about the
video stream, just as with VLC.  Do these tools do the
sort of thing I described?  (outputting the average color
of the video signal, or brightness, or something like that)
