I'm trying to load an ETC compressed texture and I'm not having luck with that format at the moment. I have not been able to find any related examples on how to load the texture once it's been compressed by etcpack. Do you have to exclude the small header ( magic number and version ) and send the rest of the data down ?
I'm currently doing the compression in memory using the etcpack code. I modified the function compressImageFile to compress to a buffer. I'm then sending using that buffer to load into gl. So far all my textures have turned out with no data. Does anybody manage to get that tool to work ?
