![]() ![]() Code complexity - like any codec, similar to decoding an ac3 frame. So, with current knowledge, even the "impossible" task of converting double-layer FEL to single-layer MEL looks quite doable - not as trivial as prefixing a byte, but not an impossible task either - decode EL layer, render data, encode coefficients back with MEL parameters, profit. And with Dolby patents released in December 2019 we now know entire DV RPU structure - MakeMKV currently detects MEL and FEL streams, and to do so it parses 90% of RPU unit. ![]() Outcome? Converting from double-PID to single-PID is a matter of prefixing a single byte per packet. For years(!!!) we have discussed what a complex job would be to convert DV streams and how million dollar software and NDA specs are required. Dolby engineering is sort of "straightforward". ![]()
