i will Always simp for the good enough 20-years-old video or audio format that Just Works and man is h.264 that
we don't need anything else we will just have h.264 + aac .mp4s for everything, the world shall heal

@hikari but but but what about HDR? :floofCry:
=> More informations about this toot | More toots from erincandescent@erincandescent.net
@hikari (actually you can do 10-bit H.264 so maybe it works?)
=> More informations about this toot | More toots from erincandescent@erincandescent.net
@erincandescent @hikari I don’t know enough about HDR to be sure but… 10-bit h.264 in an MKV seems like it could probably carry the HDR metadata even if it wasn’t technically designed to?
=> More informations about this toot | More toots from demize@unstable.systems
@demize @erincandescent @hikari HDR can definitely be carried in a H.264 stream. If I remember correctly, Dolby Vision even has a legacy HDR profile that is based off 8-bit H.264

@kanongil @erincandescent @hikari yeah, I'm not surprised--like I said, I don't know much about the technical details of HDR, but I do know that it's metadata sent alongside the video stream
so it's not much of a stretch to me that it would work with other video formats; plus I've already seen AV1 HDR encodes of things that would have been HEVC originally, which would be a lot harder if the metadata format wasn't a little portable

@erincandescent @hikari HDR is a scam made by big TV to make you buy more TVs

@jeder@miau.jeder.pl @erincandescent@erincandescent.net @hikari@noyu.me It's just like when everything had to have "3D" like 10 years ago or so.
It's pointless technology that will be abandoned by filmmakers a few years from now so if you buy a HDR display you'll be left with no actual HDR encoded films to watch.

@SuperDicq @jeder @hikari Unlike 3D, HDR doesn’t require annoying glasses and actually makes films and TV shows look better

@hikari @jeder @erincandescent @SuperDicq yeah, I don't think the idea of "you can have brighter and darker pixels" is exactly a gimmick… although I'll admit I didn't realize at first that I needed to increase the display's brightness to make it noticeable, so perhaps there's some confusion going on

@erincandescent @hikari h.264 for non-HDR, AV1 for HDR, the perfect solution

@hikari I'm thinking about AV1+Opus in Matroska containers 🙃

@9Lukas5 @hikari too CPU-intensive IIRC (PoV Thinkpads X40 and X61)

@mirabilos maybe you shouldn't use a laptop from 2004

@CounterPillow but I like it and it works extremely well and it has a better keyboard than later models, no touchpad only the IBM nipple, and a better screen aspect ratio. It’s also more robust and thicker. All plus points.
=> More informations about this toot | More toots from mirabilos@toot.mirbsd.org
@mirabilos evidently they don't work extremely well
=> More informations about this toot | More toots from CounterPillow@mastodon.social
@CounterPillow they do, their CPU oomph is just limited.
They can decode H264 when underclocked to 600 MHz at quite less than 100%CPU in top(1). Even upscaling YT format 18 to fullscreen 1024x768 is possible.
=> More informations about this toot | More toots from mirabilos@toot.mirbsd.org
@mirabilos Hey congrats, you can decode a 640x360 video in realtime. What an amazing feat. A random <$10 SoC I did measurements on once can decode a 1280x720 H.264 video at 200fps in CPU alone at less than 5W, and an equal resolution AV1 video also entirely in software at 105 fps.
Stop deluding yourself into thinking your dinosaur is any reason to stop people from using modern codecs.
=> More informations about this toot | More toots from CounterPillow@mastodon.social
@CounterPillow I don’t need 1280 as the monitor is just 1024 wide, so less CPU and bandwidth spent, which is useful anyway.
=> More informations about this toot | More toots from mirabilos@toot.mirbsd.org
@CounterPillow also, stop being so condescending. I’d like to see you have to wait for the longer video download in countries with bad and slow internet connections while I can get my smaller video, even put it into mfs/tmpfs, and watch it from there before you’re finished.
=> More informations about this toot | More toots from mirabilos@toot.mirbsd.org
@mirabilos but you're getting the less efficiently compressed video because you're relying on ancient codecs? That is the whole point of more advanced codecs, they are more efficient at cramming the same perceived quality into smaller bitrate, or more quality into the same bitrate.
That you're here bragging about fitting an entire video into RAM is quite funny; I can do the same and then some.
=> More informations about this toot | More toots from CounterPillow@mastodon.social
@CounterPillow it’s fun you say "less efficient" because the H264-compressed video is more energy-efficient, the AV1-compressed one is merely a smaller download. So, very much no.
=> More informations about this toot | More toots from mirabilos@toot.mirbsd.org
@mirabilos predictable argument twisting semantics because you exposed yourself as an irrational idiot. I'm sure your inefficient (energy) ancient hardware downloading an inefficiently (bandwidth) encoded video is totally efficient, bro. Except I'm sure you'll try shifting the goalposts again towards something else, maybe grey energy.
Just take the L you fefeclone gigaclown.

@CounterPillow I tried serious arguments but you’re apprently only interested in being insulting (and perhaps that’s why you dropped the rest of the people involved in the thread, I should have known). sigh… not worth my time

@mirabilos @hikari Encoding is a time pain point, yes.
Viewing works fine with my machines already and the decision is for a long-term plan of archiving.
=> More informations about this toot | More toots from 9Lukas5@mastodontech.de
@9Lukas5 @hikari AIUI the encoding/compression to decoding/decompression point moves in favour of less compression if it’s viewed/transferred a smaller amount of times. With archiving, storage space does become a concern again, but that’s something you’ll have to weigh for yourself then.
(Recompression of an already lossily-compressed thing will also lose quality.)

@hikari I love your enthusiasm! I agree that for the vast majority of people these are perfectly fine.

@hikari
doesn't ffmpeg already encode h264? (and 265?)
does it have a clean-room implementation that works, and so doesn't need a licence?
sorry, I'm no expert but I do recall some debates years ago about royalty-free in the context of open source

@rzeta0 @hikari libx264 has been around for ages. There was also divx and xvid, all H.264 codecs.

@hyc @hikari
thanks Howard
so how they get around the patent issue?

@rzeta0 @hikari no idea, really. They don't even mention it https://www.videolan.org/developers/x264.html

@rzeta0 @hyc they don't

@hikari Reminds me back in 2017 when the MP3 patents expired and the news articles were all about why everyone should switch to a new, patented encoding format.
Um, no thanks, 320kbps MP3 works just fine for storing music.
Literally any audio device made in the past 30 years can play an MP3, without fuss.

@grillchen @twinspin6 @green sad irony that anime people seem to be suspicious of vlc (because supposedly it has synchronisation or decoding issues or something) and prefer mpv, if that's their attitude
