I think it would only be studied if someone (like for example you) would do that study, that is compare it to current ffv1 and suggest it as an algorithm for a future version. Of course you would only do that if/when you see that as making sense. For example when it is better than the current code, supports lossless and arbitrary image sizes ... What i wanted to say with my reply is more that suggestions to extend ffv1 in ways that improve it would be welcome. > > Just first I wanted to point out that the NHW Project is very experimental > for now.For example there is no lossless mode and it is now only for > 512x512 image size... > > Do you plan to add to FFV1 a lossy intra-coded picture mode? That would only make sense if that is either a very simple & natural extension to existing code or if it adds significant value over other existing codecs. > > Maybe first and before going deeper, you can try the NHW Project and see if > in its current state it can be interesting for FFV1? > > Many thanks again! > Cheers, > Raphael > > > > Le jeu. 4 oct. 2018 à 14:37, Michael Niedermayer <[email protected]> a > écrit : > > > Hi Raphael > > > > On Wed, Oct 03, 2018 at 06:42:01PM +0200, Raphael Canut wrote: > > > Hello, > > > > > > Maybe it could be interesting for professional people of this list, I > > have > > > improved the NHW Project image compression codec. > > > > > > This new version is better and I have added very high compression, which > > is > > > very competitive with x265 (HEVC).Maybe this version could be now > > > interesting for the IETF video codec working group... > > > > > > For reminder, the NHW Project has more neatness than x265 (HEVC) and I > > find > > > it visually more pleasant, it is royalty-free, and it is at least 50x > > > faster to encode and at least 15x faster to decode than x265 (optimized > > > HEVC)!
