Hi,

I'm using OpenGL ES 3.0 libs that came with AdrenoSDK 3.6 for Windows7 64 bits.

glCompressedTexImage2D does not work as expected: 2348 KB are allocated when calling this function with the following setup:

Code :
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
GLuint handle;
glGenTextures(1, &handle);
glBindTexture(GL_TEXTURE_2D, handle);
GLenum _format = GL_COMPRESSED_SRGB8_ALPHA8_ETC2_EAC;
dword _width = 128, _height = 128, _bpp = 8;
dword _size = (128*128*_bpp)/8;
byte *_pdata = (byte*)malloc(_size);
memset(_pdata, 0, _size);
glCompressedTexImage2D( GL_TEXTURE_2D, 0, _format, _width, _height, 0, _size, _pdata );

Does anyone has any idea what am I doing wrong?

Help would be much appreciated,

Thanks!
