zsoltiv__: animated JXL encode is not supported at this time
<Traneptora>
only decode

I don't intend to support animated jxl encoding as IMO "animated images" were a mistake
<Traneptora>
animated JXL only exists for feature parity with GIF and WebP, you shouldn't use it

stabs elenril.
<elenril>
mwahaha
<elenril>
there's not enough cosmetics reviews these days
<Lynne>
people stopped submitting patches with bad coding style after I started telling them to
<Lynne>
feedback works, somehow even new contributors don't make bad coding style patches after I stopped being bothered
<Lynne>
also: prores patches have appeared!
<elenril>
along with a wild ubitux

Traneptora: i know, i'm trying to add support for it. the encoding works now, i just need to pass `-f rawvideo`, which is what i was asking about

ffmpeg xufuji456 master:341a483b0868: avdevice/audiotoolbox: silence warning with new api
<Lynne>
is it true that if the h264 decoder gets AVCDecoderConfigurationRecord extradata, it assumes the stream is not annex-b?

slaps elenril with 16 columns of white spaces
<bcheng>
Lynne: thanks
<Lynne>
sure
<BBB>
ubitux: really obscure method to get to a very desirable outcome. thanks for working on merging proresencs :)
<Lynne>
btw, does anyone have the VC-6 specs (ST 2117-1)? I'd like to take a look at them/laugh at them, but they're not on the public
<Lynne>
I found a pdf on a chinese website for the great price of 10 renminbi (1.3 euros), but that's too steep for me
<courmisch>
renminbi is a lie
<courmisch>
elenril: where a test case for lpc autocorrelate as penitance for calling my code base64
<courmisch>
write, even
<Lynne>
s/renminbi/chinese pesos
<elenril>
I did not call it that
<elenril>
I merely implied it
<courmisch>
have fun taking over the RISC-V porting
<courmisch>
I left all the difficult and/or untested functions for you to do
<courmisch>
we can arrange hardware access for you, so don't try that excuse
<courmisch>
also fix avpriv_find_start_code so that it can be DSPd
<courmisch>
Lynne: do you know if the lag in LPC compute autocorr is always nontrivial enough to vector according to that rather than the input length?
<courmisch>
if I can vector against the lag, then I can skip reloading the data

also FFmpeg is mentioned by name 8)

elenril: last i read they explicitly mentioned ffmpeg as evil
<elenril>
ooh, senpai noticed us
<courmisch>
"evil" sounds defamatory enough to sue
<JEEB>
> Using any unauthorized implementation (such as the FFmpeg and derivative implementations)...
<JEEB>
of course they don't call us evil
<courmisch>
okay so now you need to fix the implementation *then* send a cease and desist
<JEEB>
well it's not really about fixing, it's about being *authorized*
<JEEB>
:D
<courmisch>
"might lead to
<courmisch>
decoding errors, performance degradation, incompatibility, and instability"
<JEEB>
yup
<courmisch>
derogatory business interference
<ubitux>
i have two different bugs with both our encoders though here
<JEEB>
the "might" is probably what they'll point at
<Lynne>
we're evil because we don't care about their patents
<Lynne>
joke's on them, they're not going to stop us because we can't even read them!

Traneptora: re: png, not supported in what capacity? What is wrong with decoding the data as is and tagging it to let decoder users convert to correctly according to thier needs? What was wrong with previous status quo?
<kasper93>
I'm confused because because ffmpeg cannot round-trip png files, because it will save tagged limited range rgb png, but decoder ignores it, so the output is wrong.

I see some stuff on the ffmpeg-devel archive that never made it to my inbox.
<kylophone>
Yeah, not there either. Was wondering if this has happened for others?
<kylophone>
Of course the failure could be on my side, but I use google, so that should be pretty solid (I hope).
<JEEB>
since I have a message with > Rev2 with padding and doc. in my ffmpeg-devel box, I seem to have that message
<kylophone>
OK, must be on my side I guess.

<jkqxz>
Is it a mmap/sbrk effect that would make it hard to get access to other peoples' naughty videos by sending malformed streams to transcodery things?
<jkqxz>
This feels like such an obvious hole that it probably doesn't actually work.
