<Daemon404> BtbB, parse it, add it, reformat
* Daemon404 runs
<Daemon404> (as an aside i recently looked into our use of dates in hls when someone asked about clock drift on video-dev... i regret looking at it.)
<haasn> https://0x0.st/H5V9.txt does anybody recognize this encoding or know what it could be?
<haasn> it's definitely not a golomb code
<elenril> ask paul?
<elenril> that looks like a blatant LGPL violation
<elenril> "totally not stolen from avcodec"
<kierank> elenril: I can tweet it if you want
<jamrial> yeah, that's obviously cbs
<elenril> kierank: go ahead i think
<Daemon404> i find it funny people wpuld steal av1 code from ffmpeg
<kierank> done
<Daemon404> there are a lot of permissively licensed versions
<Daemon404> evej one written by me :D
<Daemon404> even*
<jamrial> kierank: should have not added the offset to that one line, as it makes it seem it's about it rather than the entire module
<Daemon404> dlete/retweet
<Daemon404> delete even
<elenril> Daemon404: lavc is superior, duh
<kierank> done
<Daemon404> elenril, ofc
<another|> bird site now completely broken it seems. can't even load deeplinked posts
<another|> ah, was deleted

<elenril> Daemon404: 38 patches just for you
<jamrial> elenril: re sizeof avoptions, maybe a bitfield?
<elenril> for extra pain?
<jamrial> eh, that's like using uint16_t now that i think about it
<elenril> exactly
<jamrial> so nevermind
<Daemon404> elenril, oh... thanks?
<elenril> then again I'm not very sure we want it at all
<elenril> and I don't see any immediate uses for it
<Daemon404> elenril, i will give it a thorough rea-through, and build it with my codebase on sat/sun
<Daemon404> ive had a combined 5 hrs of sleep over the last 3 days so any review from me tonight is worthless ;D
<elenril> party hard
<Daemon404> random insomnia hard
<Daemon404> though i *do* feel hung over
<elenril> hallucinations?
<Daemon404> lol no
<elenril> I hear you're supposed to get them around 48 hours
<Daemon404> although kierank did send me a picture of myself covered in pink elephants yesterdy
<elenril> I do not kinkshame

<jamrial> elenril: i suppose the array opt stuff can't be used for https://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavutil/iamf.h;h=93785d9fec20e2d4f28599ad0f1b39f275ede707;hb=HEAD#l157 right?
<jamrial> but it can for https://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavutil/iamf.h;h=93785d9fec20e2d4f28599ad0f1b39f275ede707;hb=HEAD#l331 if i add the nb_ int after it
<elenril> right
<jamrial> ok, guess the first will remain avoptless then
<rodeo> and here I thought Ba'al was a Goa'uld (I mean, they're all very loosely based on actual deities, but for some reason I never bothered to look up the inspiration for this particular character)
<Lynne> baal is the final boss of d2 lod, no idea what you're talking about

<courmisch> mail folder terror bombing
cone-052 has quit [Quit: transmission timeout]
<elenril> that's nothing
<elenril> and your client should fold all that into a single thread anyway
* courmisch stabs elenril
<courmisch> my client automatically expands threads with unread messages, as it should
<elenril> configuration issue
<courmisch> I will report you to the FFmpeg Mail Commitee
<elenril> senpai status=noticed
<courmisch> you're a little old for chuuni
<elenril> reported to el presidente for defamation
<courmisch> you can't do that, I set the constitution to True Separation

<Sean_McG> hi :)
<rodeo> hello
<Sean_McG> does the owner of the x86_64-archlinux-gcc-ubsan FATE node (listed in the tool as 'ubitux2') hang out on IRC?
<JEEB> ubitux does join every now and then :)
<jamrial> yes, but he's not online atm
<Sean_McG> I'm hoping to ask them if they can flush their ccache for that node as I think the test failures might be from previous miscompiles.
<Sean_McG> (I've tried to reproduce the same failure locally and not had any luck)
<jamrial> did you use the same gcc binary from Arch?
<Sean_McG> no, in fact I'm actually working on a Debian 12 machine, so gcc 12.x -- but looking at the notes for what changed in gcc 13, I don't think there was anything related to ubsan, unless it was just missing from the release notes
<Sean_McG> I suppose I could spin up an Arch VM -- maybe I will see if I have some time to do that this weekend
<JEEB> for a quick sysroot often a podman/docker run with bash might be enough :)

<Lynne> Sean_McG: I've pinged ubitux
<Sean_McG> cheers :)
<Sean_McG> also I looked at the build failures on the MIPS node -- it looks like an absolute hot mess to fix
<Sean_McG> some of the accel code for MIPS has been using instruction sets not available in the original mips1 -- and in the meantime there are other complications because of: 1) Loongson 2) gcc defaults changes on that platform with 5.0 and later, and 3) even glibc requires a mips2 now
<Sean_McG> so it's tough to find the lowest common denominator
<Sean_McG> we also didn't have any big-endian coverage until I added my QEMU PPC one earlier this week
<Sean_McG> (I guess my memory is hazy, I always thought at least SH4 and the older ARM were big-endian)
Guest14 has quit [Quit: Client closed]
<haasn> elenril: oh, sorry for missing mastering display metadata :)
<haasn> Lynne: found it, it's EMDF variable_bits(n)
<haasn> which is N bits followed by a 1 bit flag to read more (or not)
<JEEB> is it the same EMDF as the (E-)AC-3 one?
Guest14 has joined #ffmpeg-devel
<haasn> dunno

<Marth64> happy Friday
<Sean_McG> same to you
<Marth64> thx
<haasn> JEEB: yeah, it's the exact format from the EAC-3 pdf you linked
<JEEB> ok so at least something matches lol
<JEEB> I still find it hilarious how they threw that in there

<JEEB> since they could just define a private T.35 payload
<JEEB> like x264 f.ex. does
<jamrial> <haasn> which is N bits followed by a 1 bit flag to read more (or not) <- sounds like leb
<quietvoid> JEEB: they even partially setup a registration page for it
<JEEB> yea, I recall that
