Nova Aurora
2021-02-01 04:36:47 Is that so slow it takes centuries to encode or so fast that it doesn't encode detail?
Fox Wizard
2021-02-01 04:39:53 CPU 0 is... extremely slow
2021-02-01 04:40:16 Like, could take days for a few minutes video at 10 bit <:kekw:758892021191934033>
2021-02-01 04:42:06 At least 8 bit is a little bit better speed wise, but gotta go all or nothing
Nova Aurora
2021-02-01 04:42:12 How much has libaom improved? the last time I gave it a good test it took 2 hours to encode 5 minutes on my computer.
Fox Wizard
2021-02-01 04:43:05 Not sure to be honest, but seen several speed improvements
2021-02-01 04:44:31 There's a noticeable difference though, even compared with about half a year ago

2021-02-01 05:28:18 Which one would be better as emoji? ~~yes, I'm this bored~~
2021-02-01 05:28:18
_wb_
2021-02-01 05:28:42 100x faster is probably not quite the same encoding then, <@!424295816929345538>
Fox Wizard
2021-02-01 05:29:35 I apparently already added that emoji before I asked that, guess I can see the future <:PepeOK:805388754545934396>

2021-02-01 05:29:54 <@794205442175402004> old encoding was sooooo slow

2021-02-01 05:31:00 All new version they reduce some accuraci for speed
Nova Aurora
2021-02-01 05:31:31 But 100x is insane

Nova Aurora
2021-02-01 05:32:00 That's on the level of hardware encoding most of the time
Fox Wizard
2021-02-01 05:32:01 VP9 emoji, because... 🤷
Nova Aurora
2021-02-01 05:32:53 If they pulled that off in software I'd either be amazed or wonder how much useless calcuations they were doing
_wb_
2021-02-01 05:33:02 unless they were doing something very bad before, a 100x speedup is something I only expect from skipping coding tools or trying fewer modes
Crixis
2021-02-01 05:33:51 They removed a lot of filters and tools
veluca
2021-02-01 05:35:35 then again, AFAIU their transform selection code is something like 50x slower than the one implemented in JXL, so...
Crixis
2021-02-01 05:35:56 Now they have clips that decode at 20 fps and clips that decode at 120 on same hardware
2021-02-01 05:38:24 Av2 presentation by netflix was all on performance and efficiency on software, no more complexity
Nova Aurora
2021-02-01 05:40:26 Trying it out now it's about the same

2021-02-01 05:43:58 Today I've tested webex version, it was much better of x264 but 0 reliability on libaom
2021-02-01 05:47:02 Zoom also was very good but I don't know the codec
2021-02-01 05:47:42 Teams was x264 trash
Fox Wizard
2021-02-01 05:48:45 Apparently Zoom uses SVC
2021-02-01 05:48:59 Do we need more codec emojis? <a:thinkShape:676826305089634304>
BlueSwordM
2021-02-01 05:49:17 There are multiple reasons for that. 1. Better threading. 2. Lots of SIMD optimizations since then. 3. Lots of code optimizations. 4. Smarter feature activation, change, or disabling because it either made the encoder slower for no reason. 5. Using more efficient techniques allowed for activation of speed features without making the encoder have worse efficiency than baseline.

2021-02-01 05:49:49 Oh wait, gotta add VVC
BlueSwordM
2021-02-01 05:50:52 There are also a lot of other optimizations that are coming that could make the encoder considerably faster and more efficient, but they're still either being worked on, or not activated due to other priorities.

2021-02-01 05:52:26 That logo is better
BlueSwordM
2021-02-01 05:52:32 But yeah, there's still a lot to squeeze out of AV1.
Fox Wizard
2021-02-01 05:52:37 AV1 has a <:PepeOK:805388754545934396> logo. Especially compared with the other logos
BlueSwordM
2021-02-01 05:53:17 SVT-AV1 does have the speed advantage at speed 6 and above, but that speed advantage goes out the window once you go below that, which is where aomenc shines.
Nova Aurora
2021-02-01 05:53:40 JXL's 'logo' (the one we have a emoji for) is just something Jon threw together for his website, right?
2021-02-01 05:55:24 This is the one on the jpeg website

2021-02-01 05:56:26 Just there are no image format logos (which is closer to this server, like Jpeg, AVIF, HEIC, WebP, WebP v2), except for JXL
Fox Wizard
2021-02-01 05:56:27 That one might look a little too small as emoji. Especially when added as reaction <:SadCat:805389277247701002>

2021-02-01 07:32:56 **Copied from the AV1 Discord** JPEG XL handles **literally __every__ possible feature you could __ever__ expect from an image codec**. It's as complete as it could be, no trade-offs... ok, it can do better at low BPP, but the encoder's not optimized for that *yet*, and hey, at least it can handle it.
Nova Aurora
2021-02-01 07:33:28 That's a bold statement

2021-02-01 07:59:24 Modular is quite a bit better at very low BPP vs VARDCT. In this case, it's VARDCT as Scope pointed below.

2021-02-01 08:07:38 the current encoder will not go arbitrarily low, but theoretically, you could encode any resolution image to 100 bytes if you want with modular

_wb_
2021-02-01 08:08:01 current encoder caps quantization at some point so it won't let you do that

2021-02-01 08:08:14 to be fair, at those bitrates, you're better off downsampling the image

2021-02-02 01:25:04 I know people who have a higher than average IQ and act like they don't have a brain and I know some people who have a lower than average IQ and come over as actually intelligent people
2021-02-02 01:25:56 There's a threshold though. Can't say that I ever met an intelligent person with a very low IQ (about the range of 70 - 80)

2021-02-02 01:34:43 No problem solving (ironically he had to ask help from someone with an IQ of 74 all the time), meh at math and language skills are about average
2021-02-02 01:38:44 Lol. Can't deny that that can be fun to do
2021-02-02 01:39:50 And lol. For some reason MKVToolNix kinda breaks audio for me, but when I put it in file optimizer (which reduces the file) after it got broken it somehow gets fixed <:PepeOK:805388754545934396>
2021-02-02 01:49:10 yes
2021-02-02 01:49:19 Can be useful
2021-02-02 01:49:50 Reduces file sizes in a lossless way (small reduction for jpg, but decent reduction for png)
2021-02-02 01:50:17 It basically uses many tools, so you don't have to run a PNG through 16 tools for the best result
2021-02-02 01:52:13 Especially useful for games with devs who don't know how to properly deal with images. For example, PNGs with 1 color and transparency and (almost) fully flat images
2021-02-02 01:52:22 That's an extreme result though
_wb_
2021-02-02 02:09:18 cjxl by default keeps the invisible RGB intact when doing lossless and thrashes it when doing lossy
2021-02-02 02:09:57 we should probably make an option for that so you can choose what it does
2021-02-02 02:11:15 keeping invisible RGB intact when doing lossy was not good because when PNGs get optimized, the invisible RGB can become a stripy mess that is quite expensive to encode with DCT and that can bleed a bit into the visible pixels
2021-02-02 02:11:50 for lossless we just keep it to be safe, but for some use cases you would probably want it destroyed too
2021-02-02 02:13:04 in FLIF, there was a bitstream feature of (optionally) having RGB literally not encoded when A is zero, so the decoded RGB values can be undefined for A=0 pixels
2021-02-02 02:13:47 that's quite expensive to do though, because it means you have to check A to see if you need to decode a pixel or not
2021-02-02 02:13:54 so quite bad for decode speed

2021-02-02 02:17:59 tiff is kinda shit. You can use it if you need multiple layers n shit.

2021-02-02 02:58:59 I don't think much research has been done on compressing that

_wb_
2021-02-02 03:01:56 Tiff can do premultiplied alpha, which has the effect of destroying invisible alpha and reducing bit depth of semitransparent pixels
2021-02-02 03:02:31 Jxl also supports that, but only does that by default for EXR input
2021-02-02 03:03:55 Tiff can do anything - premultiplied or normal - but often premultiplied is done for some reason

Master Of Zen
2021-02-02 04:16:07 yeah, free hints)))
2021-02-02 04:16:40 ask whatever you want
Nova Aurora
2021-02-02 04:17:06 How did you get transparency?
2021-02-02 04:17:20 I only get the titlebars transparent when I try
Master Of Zen
2021-02-02 04:23:16 You install this ``` community/kvantum-qt5 0.18.0-1 [1000.10KB 7.20MB] [Installed] SVG-based theme engine for Qt5 (including config tool and extra themes) ``` Switch in system settings -> Application style to kvantum
Nova Aurora
2021-02-02 04:24:00 You're using arch/manjaro?
Master Of Zen
2021-02-02 04:24:02 Using kvantum manger, install and change your theme to any that have transparency in it
2021-02-02 04:24:18 arch, it's both accessible for arch and manjaro
2021-02-02 04:24:38 kvantum theme > https://store.kde.org/p/1378414/
2021-02-02 04:24:53 Or install jus everything of that theme
2021-02-02 04:25:54 For console it's quite easy, you need just to go to right click in console -> edit current profile -> appearance tab -> edit..
2021-02-02 04:26:03
2021-02-02 04:26:30 click blur and slide transparency for desired level
2021-02-02 04:26:53 >Also, kvantum require reloging to make it in power

2021-02-02 04:27:24 which kvantum folder are you using?

Nova Aurora
2021-02-02 04:28:46 yes
Master Of Zen
2021-02-02 04:29:03 It's when you want to install new one
2021-02-02 04:29:39 you unpack theme, select it, and click install -> it's installed and can be selected in second tab
2021-02-02 04:29:48
2021-02-02 04:37:58 Btw this is also my desktop from a while ago transparent discord and vs code

2021-02-02 04:38:30 cool
2021-02-02 04:38:51 I have gotten transparency, now to find a good theme
Master Of Zen
2021-02-02 04:39:04 👍
2021-02-02 04:39:44 For icons `korla`, `uos-dark`(deepin icons), `ariake`
2021-02-02 04:40:55 Good start is Global Themes, there a lot of "all together" solutions
Nova Aurora
2021-02-02 04:41:37 yeah that was what I was doing and wondering why 'transparent' themes weren't working
Master Of Zen
2021-02-02 04:45:09 btw you can force widows to not have title bar
2021-02-02 04:45:24 so console will be like this
Nova Aurora
2021-02-02 05:08:52 That's a horrible thing to do to the poor widows
Master Of Zen
2021-02-02 05:11:10 totally fine, I use super + left/right mouse for grading/resizing, super + side mouse buttons for minimize/maximize

2021-02-02 06:46:03 oh for like patching?
Crixis
2021-02-02 06:46:45 I don't know, is an idea
2021-02-02 06:48:16 But it must know what to search
2021-02-02 06:49:52 It can help in already found patch for more match on slitly different bg

2021-02-02 08:01:27 if they're smart they would release the protocol so you could write your own customization software
2021-02-02 08:01:32 or maybe someone will reverse engineer it

2021-02-02 08:02:21 or if you want to use it on linux or bsd or something that isn't an x86 windows pc

2021-02-03 06:56:25
2021-02-03 06:56:55 Can you encode this in modular s7 q100 and post there
2021-02-03 06:57:25 is 25 mpx my pc can't do this
_wb_
2021-02-03 06:57:37 That's a jpeg?
fab
2021-02-03 06:57:40 yes
2021-02-03 06:57:46 how to reduce filesize
2021-02-03 06:58:02 or modular s7 q100 or s4 q 99.2
2021-02-03 06:58:08 not the developer but any user
2021-02-03 06:59:17 ah some images haven't loaded but is the same
_wb_
2021-02-03 07:00:52 probably best to just do lossless jpeg recompression on that one
fab
2021-02-03 07:01:20 why firefox capture images in jpg
_wb_
2021-02-03 07:01:22 ```Read 1349x19375 image, 178.9 MP/s Encoding [JPEG, lossless transcode, squirrel], 4 threads. Compressed to 2926147 bytes (0.896 bpp). 1349 x 19375, 32.22 MP/s [32.22, 32.22], 1 reps, 4 threads. ```
fab
2021-02-03 07:01:35 which encoder
2021-02-03 07:01:42 dev encoder or git
_wb_
2021-02-03 07:02:12 shouldn't be very different
fab
2021-02-03 07:02:29 ok
2021-02-03 07:02:35 thanks
_wb_
2021-02-03 07:02:39 decoding jpeg to pixels and then doing lossless is larger
2021-02-03 07:02:43 ```Read 1349x19375 image, 94.3 MP/s Encoding [Modular, lossless, squirrel], 4 threads. tcmalloc: large alloc 1073741824 bytes == 0x558228e64000 @ tcmalloc: large alloc 2147483648 bytes == 0x558268e64000 @ Compressed to 5171029 bytes (1.583 bpp). 1349 x 19375, 0.87 MP/s [0.87, 0.87], 1 reps, 4 threads. ```

2021-02-03 07:03:20 squireel
_wb_
2021-02-03 07:03:38 btw that image is too large for WebP
2021-02-03 07:04:01 according to skal it should not exist
fab
2021-02-03 07:04:19 someone in AV1 discord sent an 16 mpx AVIF
2021-02-03 07:05:01 friendbesto
_wb_
2021-02-03 07:05:11 that is possible, using multiple av1 bitstreams tiled together
fab
2021-02-03 07:05:13 you could send also a 16 mpx webp
2021-02-03 07:05:26 multiple webp bitstreams is possible?
_wb_
2021-02-03 07:05:32 nope
fab
2021-02-03 07:05:34 with mozilla firefox?
2021-02-03 07:05:39 and xnview?
2021-02-03 07:05:48 and imagemagick?
2021-02-03 07:05:55 and chrome?
_wb_
2021-02-03 07:05:56 well you can do 16 megapixels
2021-02-03 07:06:09 but it has to be sufficiently square
fab
2021-02-03 07:06:27 ah so fixed resolution
2021-02-03 07:06:32 ok
_wb_
2021-02-03 07:06:34 the image you sent has a height of 19375 pixels
2021-02-03 07:06:51 webp cannot do more than 16k wide or high
2021-02-03 07:07:09 so you can do 256 megapixels as a 16k x 16k image
2021-02-03 07:07:19 but not 20 megapixels as a 1k x 20k image
fab
2021-02-03 07:07:57 ok
_wb_
2021-02-03 07:08:08 and webp2 will have the same limitation

2021-02-03 07:23:12 we can do `.jpegxl` and `.jxl`
2021-02-03 07:23:35 is anyone doing `.avf` or something instead of `.avif`?
Master Of Zen
2021-02-03 07:41:34 `.jxl` is better (imo)
