Here's one possible way to do it: https://github.com/ARM-software/astc-encoder/compare/4.7.0...YunHsiao:astc-encoder:rdo

@MarkCallow Thanks for the feedback, `rdo-lookback` is just `uastcRDODictSize` divided by ASTC block bytes (16) and `rdo-level` is exactly the same as `uastcRDOQualityScalar`. Afaics the parameters can be completely the...

> So the difference is one is specified in bytes and the other in blocks, correct? I think I prefer blocks. Yes but for compatability's sake I'd rather go with...

> Okay. But the KTX documentation should explain more clearly what this parameter is. I like your name of rdo-lookback. So the doc should say something like "Buffer for recording...

Here's one possible way to do it: https://github.com/ARM-software/astc-encoder/compare/4.7.0...YunHsiao:astc-encoder:rdo Still got some rough edges to be ironed out but feel free to work on top of it.

I've reached a point where I think most of the work is solid, but I'd love some second opinions: * The whole process is implemented as a separate step with...

Okay finally had some time to get to this... Although I wasn't able to make a full performance report, some simple test can still provide useful insights: For a 2048x2048...

Alright, like I said in the beginning this is only one possible approach to do this, it is not ideal but to some extent it perfectly works. I came for...

It perfectly works bcs any invalid trial blocks are rejected aggressively, or at least I tried my best to do so. In practice, on top of a reasonable block-size selection...
