I couldn't find a problem with the layout of the tmp/scratchbuf buffer for small strides. > as stride becomes too small its no longer possible to store some elements > that is when they are larger Can you explain how elements can be too larger to fit? > The assert should possibly be made conditional on such too large > blocks occuring when stride is too small I'd be happy to add a condition to the assert, so that it becomes useful, I just don't know what condition that could be. But in its current form the assert is wrong, as it can be triggered even though decoding works just fine.
