I have also improved encoding speed (C optimizations). More at: http://nhwcodec.blogspot.com/ We can still save 2.5KB per .nhw compressed files. I wanted to correct my last speed measurement, with the same level of optimization, the NHW Project is at least 20x faster to encode (bpgenc -m 0) or at least 52x time faster to encode (bpgenc -m 7) and at least 15x faster to decode than x265 BPG (optimized HEVC). Many thanks and Happy New Year!!!
