I would like to test if it’s possible to run a video player on raspberry pi 3 that has the four adjustable corners (video warping, perspective correction).
First, I compiled the ofxWarp addon (https://github.com/prisonerjohn/ofxWarp ), which is an adaptation from Cinder-Warping block by @paulhoux.
It works well.
Second, I followed the OF instruction (https://openframeworks.cc/setup/raspberrypi/raspberry-pi-getting-started/) to install Raspbian on Rasberry Pi, and it also works well.
So far so good, however when testing the shader examples on RBP3, 04_ simpleTexturing, I have some issues as it doesn’t render the texture. The message I got is this one:
[notice ] ofAppEGLWindow: display(): eglSwapBuffers failed: �50
I have changed in the main file:
ofGLESWindowSettings settings; settings.glesVersion=2;
I also have read some of the other related posts, but I don’t find the solution yet. When running the ofxWarp example (a simplified version with only one screen with four corners), I also get the same error related to [notice ] ofAppEGLWindow: display(): eglSwapBuffers failed.
