Hi You are referring to these formats as described here, right? I did not find any information on RG88 in there but did you mean RG16?

I have personally never encountered these formats. Could you provide some sample files? That would really help with the impleentation.

I use this name from drm fourcc code.

Just very simple formats.

R8 is just YUV400 colored with red. RG88 is packed RG format, 8bytes R followed with 8byte G

I'm working with opengl es 3.2, and want to view saved textures. sometimes texture can be in GL_R8 or GL_RG8 format.

There are truly some strange formats out there.
