@VincAlastor: I plan to add support for av1 to Hybrid shortly after I can playback such files in MPC-HC.
(got the general support working, but can't verify that everything is okay, since I can't decode the created files) Last edited by Selur; 15th January 2017 at 20:48. |

i use the patched lavfilters as external filters in mpc-hc and seems to work very well, but not tested much for now. Last edited by VincAlastor; 16th January 2017 at 10:51. |

Not as good as a gui but I create a batch file for my AV1 testing.
here the code if someone is interested ( only cpu-used and bitrate can be set ) : for the encoder, you can drag and drop the file on the .bat icon or drag and drop when the bat is running. change the path to ffmpeg and aomenc if needed. Code:
@echo off Set file="%1" if "%1"=="" Set /p file="enter file to encode (or drag and drop ) = " FOR /F %%I IN ("%file%") DO SET filename=%%~nI set /p bitrate="bitrate ( enter = default 250K ) without the"K" = " if "%bitrate%"=="" set /a bitrate=250 set /p preset_AV1="AV1 Cpu-used (enter = 2) = " if "%preset_AV1%"=="" set preset_AV1=2 ffmpeg -i "%file%" -f yuv4mpegpipe - | aomenc - --target-bitrate=%bitrate% -t 8 --good --cpu-used=%preset_AV1% --tile-columns=4 --passes=2 --pass=1 --fpf="%filename%.fpf" -o "%filename%_av1.webm" ffmpeg -i "%file%" -f yuv4mpegpipe - | aomenc - --target-bitrate=%bitrate% -t 8 --good --cpu-used=%preset_AV1% --tile-columns=4 --passes=2 --pass=2 --fpf="%filename%.fpf" -o "%filename%_av1.webm" change the path to aomdec and mpv if needed. Code:
:start Set file=%1 if "%1"=="" Set /p file="file to decode(drag and drop ) = " aomdec "%file%" -o - | mpv.exe - --fs goto start |

It's simply too early to take a serious look at AV1 now. My own estimation would be 3 years, before it surpasses x264 for general ripping use-case. This includes decent playback support (perfect in PC platform and good enough for mobile), excellent visual quality(with comprehensive psy optimization, tuning, on a wide spectrum of bit-rate target) and affordable performance (including different levels of performance presets)
Even x265 is not completely there arguably. |

Which won't happen until av1 is officially finalized (ie. stable bitstream), and releases of libaom are made instead of just having Git master, sometime later this year, hopefully.

Yeah the next GPU Cycle should show a first introduction as well before that we might see Hybrid solutions already, with Volta there will be definitely some kind of Decoding support 100% on Nvidias side and it could be going straight to first Hardware without any Hybrid step this time at all

Playback compatibility is not a issue, as long as it remains open and hardware giants are evolved.
What the real challenge for ripping use-case is the visual quality optimization in transparent level, i.e, very high quality. Optimization for benchmark is easy, for human eyes you really need to put in a lot of effort. It takes 3 years for x265 to be there with x265 v2.0 as the milestone. But still up to now, hardware support for HEVC main10 is poor and limited, and the tuning for x265 is incomplete. Majority still prefer x264 and I don't expect it changes within one year. Let's see how AV1 progresses. Now it's still a lovely baby, may it grow up healthily. |

TL;DR: VP10 + small parts of daala/thor = AV1

This is not important, what is the basis? This may suggest that changing the name VPX on AOM. However, the contents of the files is very modified and you can no longer suggest that VP10 was base.
https://aomedia-review.googlesource.com/#/c/1008/ As regards Daala. The truth is that a handful of fixes is like one bigger patch to month. I'm afraid that Daala will not have a significant effect on the development of AV2. Unless, development Daala is out of open source technologies. Last edited by Jamaika; 18th January 2017 at 14:04. |

Latest presentation about AV1 (mainly daala tech.) at LCA2017: https://www.youtube.com/watch?v=lzPaldsmJbk
AV1 bitstream freeze will be in October 2017 |

Well.. that's the first delay (for AV1). First deadline wasn't really realistic considering that most of the experiments didn't play together yet (VP10 experiments - the nextgen2 branch was merged not too long ago) and some experiments aren't in a state to evaluate them (PVQ).

Apart from the Mobile space then i see Intel and Nvidia with first Hardware ready in late 2018.
Lot of time for HEVC to flourish tough and x265 to further improve it's overall Psy Layer if the acceptance for H.264 still stays high enough it could go well if x264 by then gets overrolled @ 4K completely it will be much harder and progress on H.266 is also gonna start with a total Psy focus, though well still have to see how Trump will impact all of this.

Google itself has shown with VP8's and VP9's treatment in libvpx that they basically either can't or don't care to provide high quality encoder software. The role of other subjects that are adding into the project now is still to be evaluated, but while they will help, again you can't expect miracles (look how slowly has Daala progressed since 2010, only to find out that their proposed techniques in the end can't be made to work, in many cases. And look how much "too little, too late" has there been over the many years of theora development). I think that the three years estimate might even be optimistic given how disappointing has libvpx been for these 7.5 years that Google has owned On2 for. |

Vp10 isn't disappointing in anyways it is very competitive overall vs MPEG

VP8 and VP9 are pretty good compared to AVC and HEVC (Google) Daala still is a research project (Xiph/Mozilla) Thor is Cisco's pet project AOMedia consolidates VP10, Daala, Thor technologies to create a new codec and a new platform to develop AV1 and future codecs from Xiph, Mozilla, Google, Cisco and a boatload of other companies have joined to make it clear, AOMedia doesnt only seem to be Google, Google has done some good stuff like creating WebM (Restricts Matroska to VP8/VP9 with Opus/Vorbis only) WebM/VPx was ruled by a iron-fisted Google AOMedia is probably more of a non-american democracy just think back, how it was in the old days, Theora was pretty average/bad my thoughts

Certainly had an impact on the implementation of Matroska to video editors and home appliances. Nothing else. What to implement the HDR function. WebM get a patent from the Adobe DNG and for what JpegXT. Codec IVF is packaged in next container WebM and already. This isn't a new idea. Less fortunate has WebP. |
