Daemon404: just when you thought it couldn't get any worse, aac also has TWO additional methods to supply preroll information, which we don't use
<Lynne>
the preroll extension element, and the basic aac low profile coreCoderDelay
<Lynne>
so in a single mov, you could have a total of 5 different methods of signalling preroll

<thardin>
a client informed me that ffmpeg's srt protocol has some kind of bug with parsing SRT URLs, specifically things like latency and password
<Lynne>
Daemon404: to be fair, there is a clear order at least, with the container trimming being applied first, and the preroll extension taking precedence
<BtbN>
mkver: I only read them, didn't compile or run them. Can do so later, currently in a train.
<Lynne>
Sean_McG: ubitux reset his ccache

thardin: I think in general we should be taking those things as AVOptions
<Lynne>
he's taking a break offline and he'll be off of IRC for a bit longer is what he told me

supposedly it doesn't work anymore

thardin: I would be surprised if those parameters were simply broken in ffmpeg. There’s a high likelihood that the user simply doesn’t understand the shell quoting rules on whatever platform they are on. But I guess we’ll see if they file a ticket with an actual command line that demonstrates their issue.

<Lynne>
wow, had no idea the aom published a generic spec for av1's film grain
<Lynne>
why?
<JEEB>
probably so that it could be referred to elsewhere?
<Lynne>
but mpeg codecs already have their own film grain implementation
<JEEB>
the MPEG one at least previously was really lazily defined
<JEEB>
since it was on the level of "uhhh this one SMPTE document might document something"
<quietvoid>
my impression is that AV1 fgs is more supported in hw than the mpeg stuff, and maybe reusable
<kurosu>
the mpeg specs has a grain id, and its syntax afair looked conveniently usable by several methods
<JEEB>
yea
<kurosu>
but AV1 FGS didn't have an acceptable sdo reference
<kurosu>
there are still chip vendors that try to do away with 0 supported - too costly for them
<JEEB>
this is btw a really weird feeling that you can refer to SMPTE specs directly :P
<JEEB>
after years and years of lolpaywall

<mindfreeze>
JEEB: they moved all papers etc to their own weird portalwhich is valiated with just email and broken search
<mindfreeze>
so it is no longer inside IEEE
<mindfreeze>
so that is how they balanced the cost, and still "legally", I have to sign-in and then add to cart for $0 and download the spec from direct URL which has nothing to do

<Sean_McG>
Lynne: cheers -- I saw the new reports on FATE and it looks like I was completely out-to-lunch on these, it does seem GCC 13.x with UBsan has more generated warnings
<Sean_McG>
I built gcc13 locally on my workstation and laptop to confirm.
<Sean_McG>
if someone has some cycle, I wouldn't mind a "yes/no/piss off" on my aacenc_pred patch
<mkver>
Seems like ubitux's valgrind boxes are broken.
<jamrial>
Sean_McG: the mov.c "insufficient space for an object of type 'struct MOVIndexRange'" one seems to be making everything fail
<jamrial>
but it may be a false positive
<mkver>
jamrial: ASAN and valgrind don't complain about this; and Clang UBSan also does not complain.
<mkver>
But now that I looked at this again I am already seeing UB wrt index_range: current_index_range = msc->index_ranges - 1 uses invalid pointer arithmetic (it points to the entry[-1] of an array). This is not accessed (therefore the other tools are quiet about this), but it is UB nevertheless.
<mkver>
I will give fixing this a try.
skinkie_ has quit [Ping timeout: 255 seconds]
skinkie has joined #ffmpeg-devel
<mkver>
Fixing the entry[-1] indeed fixed this.
<mkver>
jamrial: I can't find eee3b7e2fb0664b889e58c03f76e19ef23e4d1d8 on the list.
<jamrial>
mkver: i pushed that to see if that'd make a difference for the failures, but didn't. feel free to revert it
<mkver>
Your rationale should be included in the commit message.
<mkver>
And actually you could have tested your hypotheses locally.
<jamrial>
i couldn't, same reason Sean_McG couldn't until now
<jamrial>
i don't have gcc 13 on a system where i can run ubsan
<jamrial>
if you revert it, make it av_malloc_array instead of av_malloc again while at it
<mkver>
All the more reason to send it to the list so that other can test it.
