@Atak_Snajpera
+1 How does it change the fact that MPEG Surround hasn't seen meaningful adoption? MPEG Surround is standard since 2007 as MPEG-H is since 2015. So a period of supplantation took 8 years (?) Ben, really? |

Is AC-4 the coding scheme for all Atmos? Or is that just for web streams using Atmos? |

Is this a topic about AV1? I'm not sure I'm at the right forum.
Perhaps some people want to continue here: https://hydrogenaud.io/index.php?board=54.0 ;-) |

You will find people in very remote places with no water and no electricity but with phones. Not necessarily smartphones, but with an access to 2G/3G/4G. It's widely used to communicate, send money and other stuff. There are small, cheap solar panels to easily charge these phones. Also, a part of the internet is free. Depending on your ISP, you'll have free access to Facebook, Wikipedia and other sites. Most of the time, there are restrictions like no images or no videos. Believe me, there are many many young people who will just buy some credit/data as soon as they have money. They won't buy food or water because these people don't buy food or water. They grow their own food and fetch water at the well or the river. Pocket money is mostly for entertainment so they will buy cigarettes, candies or whatever. Anyway, back on topic. In the big cities, you have great connections. I'm working 160km South from the capital city and I have 4G+. But as soon as you leave the biggest area, you end up with 2G and sometimes no network at all. And people love streaming here. Well, they have no TV, no newspaper, no nothing. But they have a phone and an access to internet. Of course they want to see pictures and watch videos. Not Netflix of course, but Facebook is absolutely huge, Youtube is not very important here. The real problem here is the cost of the data. It's damn expensive. Browsing text can be fairly inexpensive. Images are quite expensive. Video is really a rich people thing. Personally, I'm not poor but I disable all images when I browse the internet. And I can't afford more than a few minutes of videos per week. Also, keep in mind that people don't care about quality at all. They don't want better quality for same size, they want same quality at lower bitrate, so they can save data and therefore money. So AV1 will be very very useful. Easier to stream in remote areas, less expensive, allowing better quality... Africa, South-East Asia and other areas are big markets that are growing a lot. Hardware is way behind, but apart from that it's all the same (selfie sticks, filters, nomophobia... you name it). It doesn't concern 100% of the population yet, but for the younger generation it's already a wide majority. |

AV1 proponents should hope this is a viable market, because it's probably where AV1 would have the biggest differential advantage over H.264 and a market where rapid turnover and Android-centric mobile markets could result in >50% HW decoder installed base by 2025. |

I'm a bit late on this, but I was able to confirm from a family friend with an E9 TV that the 2019 LG OLEDs already support VP9+Opus WebM files played from a USB HDD. And decoding complexity isn't always the reason for lacking format support because I was also able to confirm that, while the 2019 E9 OLED also supports VP8 + vorbis in a WebM as well as VP9 + AAC in an MKV, it does not support VP8 + AAC in an MKV. Here's the full list of tested formats and combinations that I was able to confirm that worked (all video codecs are 8bit unless otherwise noted):
And the things that didn't work (all video codecs are 8bit unless otherwise noted):
Unfortunately I didn't provide a test file that combined AVC 10bit and FLAC with other known-working codecs, like AVC 8bit + FLAC as well as AVC 10bit + AAC, so it's uncertain whether it's the AVC 10bit or the FLAC that the TV is unable to play back (though this logic doesn't apply to the MKV with VP8 + AAC as it's able to support all 3 things in other combinations, just not together). EDIT: I've since confirmed that FLAC audio is in fact supported (at least up to 192KHz 24bit, same goes for LPCM as 32float LPCM failed to work) and, as expected, it's the 10bit AVC (not a typo) that is completely unsupported on LG's 2019 OLEDs. ...though more surprising to me was that it not only supported multi-audio MKVs/MP4s with an according GUI-based audio track switcher, but even supported freaking SubStation Alpha subtitles in an MKV also with an according GUI-based toggle.

https://moisescardona.me/rav1e-gui/
https://ffmpeg.zeranoe.com/builds/ Download rav1e gui. Download the static ffmpeg with the date. (exe) Copy the ffmpeg in rav1e gui folder that you extracted (with 7-zip or winrar). Disable pipes (right at the centre that is a checkbox). If it causes problems. It still could have different aspect ratio and different framerate not PAL (.vob file) 23.9976 It supports anything with ffmpeg, and ffmpeg converts to yuv. Pipes are to not generate .yuv file. For a GUI there is also Hybrid GUI (with aomenc - svt appveyor you can download) and Svt GUI, the last by Moises (same developer as rav1e gui). |

You're welcome.
Rav1e has still 80% 120% 340% difference in quality/bitrate in videos on arewecompressed.yet AWCY. A site that codec developers use to test. SVT is too far from libaom as encoder if you see Mrsmilingwolf's user test on Reddit or on Doom9 like comparable to VP9 a bit not better. I don't know if he tests with anime or like action. Also FFmpeg has included a build of encoders (Libaom) which you check the readme file in the archive (.zip) or in lower section "Other Downloads" by clicking Readme to see which version it is. Handbrake GUI doesn't support the encoding because it's too slow and AV1 support it's only in beta. But it supports dav1d (Videolan) decoding, only 8bit is completed on general SIMD, 10 bit lacks support, so it runs without SIMD instructions. If you use a GUI like Hybrid other than ffmpeg, to encode with libaom you will need aomenc.exe. Artificial noise isn't possible with a GUI, you need ffmpeg and use libaom.

It seems that there should be scenarios and highly multicore systems where SVT-AV1 would beat libaom in quality @ bitrate @ perf, just because it would have so many more MIPS/pixel available. |

Optimisation for dav1d happening for 16 bpc on ARM64 apparently - whether that means everything between 16 and 8 I don't know.
Apparently Netflix are pushing out AV1 now too (possibly even sponsoring the new optimisation efforts?). Are we finally at the point where AV1 deserves its own sub forum? |
