# revtv

RevTV acts like a video waveform monitor for each line of video processed. This creates a pseudo 3D effect based on the brightness of the video along each line.

## Example launch line

     gst-launch-1.0 -v videotestsrc ! revtv ! videoconvert ! autovideosink

This pipeline shows the effect of revtv on a test stream.
