Hi.
i don't know astc load.
i tryed as follows.
step1 . PNG file compressed using Mali_Compress_tool ( 768X512 PNG file -> Very fast block: 4X4 Low Dynamic Range )
Output file: test.astc
step2. Using glCompressedTexImage2D(GL_TEXTURE_2D, 0, GL_COMPRESSED_RGBA_ASTC_4x4_KHR, 768, 512, 0, astc_size, imageData)
[size=2]GL_CHECK(glTexParameteri(target, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE));[/size]
GL_CHECK(glTexParameteri(target, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE));
GL_CHECK(glTexParameteri(target, GL_TEXTURE_MAG_FILTER, GL_LINEAR));
GL_CHECK(glTexParameteri(target, GL_TEXTURE_MIN_FILTER, GL_LINEAR));
astc_size : file size
FILE *f = fopen(filename, "rb");
fseek(f, 0L, SEEK_END);
astc_size = ftell(f);
fseek(f, 0L, SEEK_SET);
[size=2]
[/size]
[size=2]imageData[/size][size=2] : [/size]
[size=2]imageData[/size][size=2] [/size]= (unsigned char*) malloc(size);
fread([size=2]imageData[/size][size=2] [/size], astc_size , 1, f);
error occurs in the [size=2]glCompressedTexImage2D[/size]
[size=2]
[/size]
