Just so we're on the same page here I was saying that Daala devs succeeded in making a competitive video codec.
I'm really not sure what you're trying to say - do you think it was somehow daalas fault that we still have software patents? To mandarinka: personally i'm optimistic about AV1, the spec will be good enough that we will likely get a good encoder software finally (and also some good encoding hardware). |

Sure Intel, AMD and Nvidia are mostly only there for getting their Hardware Decoding ready to go but they also have valuable R&D in different parts that might become interesting if they decide to share them So there might be a possibility we gonna see Intel contributing some NGV IP there would be actually no better time then now for it instead of leaving everything taking dust in the Restroom

Daala finally provides color depth 10 bit. Unfortunately, the lack of support the CPU very limited coding. (max. fullhd) It's very slow. Still need to improve the player because he doesn't work.
Code:
daalaenc.exe --b-frames 4 --keyframe-rate 23.976 --complexity 5 --video-quality 18 --fpr --output "image_rate18.ogg" - Code:

Then they could have moved on to AV2 with drastic/revolutionary changes. Last edited by mzso; 19th May 2017 at 09:48. |

AV1 was never meant to have revolutionary changes - it needs to get to the market rather quickly (to still take advantage of HEVC licensing uncertainty). |

Missed my second point too. If that was the most significant aspect they should have just released as soon as they got an agreement upon AV1. VP10 + throw in whatever is considered "mature" and gainful from the others. Then start optimizing the encoder/decoder. |

There are plenty of little weird things in the VPx history where a symmetrical bug in the encoder and decoder caused strange and painful limitations for 3rd party implementations. And anything like that in AV1 couldn't be fixed until AV2, because once you have decoders shipping in hardware, you need to stay compatible with them FOREVER. There are 10+ year old H.264 Baseline Profile decoders that modern encoders can make perfectly compatible streams for. If a codec is just running as software in web browsers, things can be a lot more fluid. But not if it's going into fixed-function hardware! Or on any device that doesn't reliably get automatic firmware updates. |

OK, I agree - it is a tweaked VP9, but that doesn't mean anything. Why start from scratch when you can take a proven stable baseline and "tweak" that.
I (still) don't understand your point - that is exactly what they do now. PVQ, daala EC and deringing filter is what worked good in daala and they are integrating it into AV1. Same with CLPF from thor and things like rANS in VP10. However you can't do this overnight.. it is still a lot of work. |

On that regards im pretty eager to see if we currently stand in the middle of a transition @ Intel and AMD to FPGA IP Cores for the Video Decoding/Encoding It looks like this could happen in the not so distant future After all the Hardware (extension) activation/upgrade tests in the past.

Problem with playing and converting video to YUV 10bit.
daalaenc.exe --b-frames 4 --video-quality 25 --complexity 3 --output "daala+1660_comp3_q25.ogg" - https://www.sendspace.com/file/iknrja |

What is NGV? Was it not the codename for RV40 aka RMVB? If not is it suppose to be after RV40? Which i remembered the open it up as Helix. And what is NGV suppose to do with Intel? I really wish Real could truly open up RMVB. |

Not only you
NGV (RealVideo 11) was the Next Generation Video Codec developed at Real after their H.264 contribution (RV10) then it was stopped and complete ip and NGV Team transfered to Intel Pretty much Real Networks History as active Codec Developer ended @ that time. Karl was not among them he stayed at Real and still is there worked on some Cloud Sureplay seemless Device Transcoding and Player parts it seems 2014-16: RealTimes for Mac Though the Chinese (Asian) arm of Real still seems to actively working on the Content Creation part and also update it most probably based on the older code path (RV10) http://www.realnetworks.com.cn/en/en/RealMedia%20HD http://www.realplayer.cn/software/Re...ease_Notes.pdf Quote:

ARH!. Yes, That NGV. WHY THE HECK did Intel decide to invest in RV11 aka NGV? And then not release anything and Kill it? I think ( not sure now ), Real Producer, or the rmvb encoder itself has some of the best default Pre and Post Processing settings, you get very decent results without any tweaking or parameters. RM was crap. RMVB totally changes the game. It goes from amazing in Anime and very decent in other categories. It doesn't preserve any grain in movies, so it never did well in high quality Rips. And it is for this very reason, I never liked VP8, VP9, or VP10. Even after the acquisition of Google, they still smells of On2. |

Those are the Chroma issues still left we talk about a lot and they also showup in AV1 as well.
you can see them everywhere not only that sample http://wyohknott.github.io/image-for...:1&ogv=m&bpg=m http://wyohknott.github.io/image-for...1&webm=m&bpg=m
