10:17:54 <Sean_McG> BTW not sure who to thank, but I like the new stylesheet for FATE.
<kierank>
I don't understand the green highlighting
<kierank>
what does the highlighted green row mean
witchymary has joined #ffmpeg-devel
<nevcairiel>
builds that returned to green from another color
<nevcairiel>
similar would be yellow or red rows, they changed color in the last build
<nevcairiel>
the information was previously indicated already, just not very obvious..

mkver: did you have any ideas for the swscale gray -> gray32f floating point exception?
<mkver>
This is the first time I am hearing of this exception.
* haasn
checks memory
<BtbN>
I think git.videolan.org is also suffering the LLM-Scraper-Rush
<Lynne>
if its the alibaba scrapers, all the internet is suffering from it

my bad, it was ramiro who I was discussing the sigfpe with

<ePirat>
mkver, the deprecation warning fixes look good on a brief look.
<ePirat>
mkver, I am curious, are those just an issue for clang and gcc does not warn about these?
<mkver>
Exactly
<mkver>
GCC would not even accept the deprecation warnings inside definitions like my patch does for Clang.
<ePirat>
yeah I saw the discussion on the other patch
<ePirat>
also this will make it possible to easily switch to the new internal fields I want to add for this
<mkver>
That was also my intention.

<ramiro>
haasn: yes, I have a patch, just a second
<haasn>
ramiro: my local hotfix is just to change int bit_depth = c->dstBpc ? FFMIN(c->dstBpc, 16) : 8;
<haasn>
is yours any different?
<ramiro>
haasn: yes, my "fix" is a hack based on a similar hack :P
<ramiro>
(btw I couldn't find my patch so I just did it again).
<haasn>
hrm
<haasn>
not sure which version I prefer at this point
<ramiro>
I don't like my patch though, and I don't like the hack that's already there. I'd like to remove it.
<ramiro>
I think your fix is simpler. with a comment that says we're using 32 dstBpc for float formats, but they have an intermediate representation of 19.
System_Error has quit [Ping timeout: 264 seconds]
<ramiro>
I assume all of this will be gone with nuscale, since we won't have this internal representation anymore.
<haasn>
oh I should also comment somewhere on why I chose to use floats internally
<haasn>
but tl;dr modern CPUs good, integers bad, and floats are more accurate than the dumb 19 bit precision swscale uses anyway
<haasn>
Oh another advantage I forgot to point out is that it eliminates the ability for there to be a discrepancy between platforms, so no more things like the BITEXACT flag
<haasn>
Since _any_ implementation of a given operation will have the same semantics
<haasn>
No more things like weird fast paths that use differing precision
<haasn>
Also, the levels of abstraction involved means that platform specific code can no longer read into the SwsContext at all
<haasn>
And every implementation is paired with a setup() function that prepares whatever data it needs
<haasn>
In whatever format it needs
