lygia/sample/yuv)a way to solve the YUV camare texture on iOS
Dependencies:
Use:
sampleYUV(<SAMPLER_TYPE> tex1, <SAMPLER_TYPE> tex2, <vec2> st)
#ifndef FNC_SAMPLEYUV
#define FNC_SAMPLEYUV
vec4 sampleYUV(in SAMPLER_TYPE tex_Y, in SAMPLER_TYPE tex_UV, in vec2 st) {
vec4 yuv = vec4(0.);
yuv.xw = SAMPLER_FNC(tex_Y, st).ra;
yuv.yz = SAMPLER_FNC(tex_UV, st).rg;
return YCbCr2rgb(yuv);
}
#endif

Use:
