void main() {         vec4 color = texture2d(stexture, vtexturecoord);         float colorr = (1.0 - color.r) / 2.0;         float colorg = (1.0 - color.g) / 2.0;         float colorb = (1.0 - color.b) / 2.0;         gl_fragcolor = vec4(colorr, colorg, colorb, color.a);     }

if ffmpeg compiled libx264, can use

you can specify bgr24 or bgr0 (32-bit; has unused 4th channel)
