Support for 10/12-bit unpacked formats is missing, let's add\nit.\n\n10/12-bit unpacked formats use two adjacent bytes to store the value.\nThis means the 8-bit shaders can be used if we can modify them for\nadditional support of 16-bit addressing. This requires the following\nmodifications:\n\n- Using GL_RG (two bytes per pixel) instead of GL_LUMINANCE (one byte\n per pixel) as the texture format for the given input formats.\n\n- Setting the texture width to the number of pixels rather than the\n number of bytes.\n\n- Making the definition of `fetch' macro variable, according to the\n pixel format.\n\n- Using only `fetch' for accessing the texture.\n\nSigned-off-by: Milan Zamazal \nSigned-off-by: Bryan O'Donoghue \n---\n src/libcamera/shaders/bayer_unpacked.frag | 10 +++++++++-\n 1 file changed, 9 insertions(+), 1 deletion(-)","diff":"diff --git a/src/libcamera/shaders/bayer_unpacked.frag b/src/libcamera/shaders/bayer_unpacked.frag\nindex 114e32058..477e8bbf6 100644\n--- a/src/libcamera/shaders/bayer_unpacked.frag\n+++ b/src/libcamera/shaders/bayer_unpacked.frag\n@@ -41,9 +41,17 @@ float apply_contrast(float value, float contrastExp)\n void main(void) {\n vec3 rgb;\n \n+ #if defined(RAW10P)\n+ #define pixel(p) p.r / 4.0 + p.g * 64.0\n+ #define fetch(x, y) pixel(texture2D(tex_y, vec2(x, y)))\n+ #elif defined(RAW12P)\n+ #define pixel(p) p.r / 16.0 + p.g * 16.0\n+ #define fetch(x, y) pixel(texture2D(tex_y, vec2(x, y)))\n+ #else\n #define fetch(x, y) texture2D(tex_y, vec2(x, y)).r\n+ #endif\n \n- float C = texture2D(tex_y, center.xy).r; // ( 0, 0)\n+ float C = fetch(center.x, center.y); // ( 0, 0)\n const vec4 kC = vec4( 4.0, 6.0, 5.0, 5.0) / 8.0;\n \n // Determine which of four types of pixels we are on.\n","prefixes":["v9","16/26"]}
