/* This is a trivial program bin/stream to exercise FrameIstream and
   FrameOstream. All it does is read an InputFrameSeries, but you can
   specify the input to come from anywhere (using --in) and you can
   specify the output to go anywhere (using one or more --out
   options). E.g., to view an mpeg movie (note that we make no effort
   to actually display the movie at the proper framerate):

     ./bin/stream --input-frames=0-10000@1 \
       --in=tests/inputs/mpegclip1.mpg --out=display

   to display the contents of your framegrabber (again, we make no
   effort to sync up the framerates)

     ./bin/stream --input-frames=0-10000@1 --in=v4l --out=display

   to convert a movie into a series of raster files (the output files
   will be named starting from stream-output000000.ppm):

     ./bin/stream --input-frames=0-10000@1 \
       --in=tests/inputs/mpegclip1.mpg --out=raster

   to record 100 frames from your your framegrabber to a movie file
   (the movie will be named stream-output.mpg):

     ./bin/stream --input-frames=0-99@1 --in=v4l --out=mpeg

   to view some white noise in case you are bored:

     ./bin/stream --input-frames=0-999999@1 \
       --in=random:1024x1024 --out=display
