At stb-tester.com we use image processing to perform automated black-box testing of set-top boxes. This means that we capture video over HDMI and look for UI elements based on screenshots we'd previously captured. This works great for set-top boxes, but what about Smart TVs which don't have an HDMI output?

This talk will describe how we use GStreamer, OpenCV and OpenGL to go from an image captured with a camera back to a nice flat image as if it had been captured over HDMI.

William Manley is software developer and a co-founder of stb-tester.com, a company that provides automated testing equipment and services for set-top box manufacturers. In a previous life he worked on set-top box middle-ware. He has been working with GStreamer since 2012 with a particular interest in v4l and sending video over IPC.
