Request: Invert video (180 rotate)

[abibias]

Would be possible to rotate video (180 degrees)?

Good idea. I'll have to add this to the list of features to add.

Until then, adjusting the x/y coordinates of screenQuad should do what you're after https://github.com/meekys/cam_overlay/blob/master/cam_overlay.c#L264

ie. (Untested) Rotate: static GLfloat screenQuad[4][5] = { // x, y, z, u, v { 1.0f, -1.0f, 0.0f, 0.0f, 0.0f}, // Top left { 1.0f, 1.0f, 0.0f, 0.0f, 1.0f}, // Bottom left {-1.0f, -1.0f, 0.0f, 1.0f, 0.0f}, // Top right {-1.0f, 1.0f, 0.0f, 1.0f, 1.0f} // Bottom right };

Flip: static GLfloat screenQuad[4][5] = { // x, y, z, u, v {-1.0f, -1.0f, 0.0f, 0.0f, 0.0f}, // Top left {-1.0f, 1.0f, 0.0f, 0.0f, 1.0f}, // Bottom left { 1.0f, -1.0f, 0.0f, 1.0f, 0.0f}, // Top right { 1.0f, 1.0f, 0.0f, 1.0f, 1.0f} // Bottom right };

Thanks a lot! Works perfect! ;)

Will this work for mirroring as well? Right now I need to have my image mirror flipped.

Latest commit should allow you to flip horizontally, vertically, and also rotate. Hopefully that should cover all the scenarios you'll need.
