Ask HN: A realtime video warping solution
For the past few months I've been struggling to find a solution to creating a sub-$200 realtime HD video warping solution.
I'm developing a curved display product and I need a solution to perform geometric correction of regular flat/rectangular content so that it appears fine on the curved surface.
To perform the warping I can do it at various levels:
1. At app level utilising software that incorporates the warping for specific purposes (I've got a few that do this).
2. Using desktop warping software. I've come across $500+ warping solutions for Windows, Mac and Linux. Noting on Android. These solutions are not user-friendly
3. Utilise an existing commercially available warp box. A/V providers who have digital scaling solutions supply these. They're pretty expensive: $3500+
4. Find a projector with built-in warping capabilities - these are generally $4000 to $17000
5. Build my own warp box: I've found semiconductor companies with chips that perform geometric correction. However they only supply evaluation boards. To design my own PC Board with HDMI-in & HDCP that warps the content and outputs via HDMI is probably going to cost beyond $10k after development and certification.
6. Use an Android Media Player with HDMI in/out and HDMI passthrough capability to warp the content in realtime utilising OpenGL mapping techniques. I've been searching for a freelancer on various platforms that can help me do this on an Android Media Player that I believe offers the potential to be a low-cost warping solution but to-date I have had no luck in finding a developer that can do this.

Is their anyone on HN that can suggest a viable warping solution and/or help me develop it? Will pay for it.
