durandal_1707: you should talk to duke abaddon about this
<elenril>
I'm sure you'd find much in common
<elenril>
kierank: gitea > gitlab
<elenril>
and if it's supposed to be a serious project, it mainly needs a diplomat rather than a sysadmin
<kierank>
I meant being ignored by Paul
<kierank>
elenril: 50/50 on that
<elenril>
nonsense, paul is my biggest fan
<kierank>
We use gitea at work
<elenril>
and what's wrong with it?
<elenril>
also, BBB reportedly had tons of funding for moving to gitlab or similar
<elenril>
so the problem is not funding
<elenril>
the problem is someone being able to persuade people and organize and manage it without the community going critical
<kierank>
True for all the projects imo
<kierank>
In stf
<elenril>
ossfuzz and coverity are not that controversial
<kierank>
True, a lot of the coverity ones are false positives
<elenril>
yes, that's something that also concerns me about that project
paulk has quit [Quit: WeeChat 3.0]
<Daemon404>
is it a "project" if it is infinitely ongoing?
<elenril>
it is, because it's limited to one year
<Daemon404>

if i really wanted to troll i would propose a project to modernize our infra and bring it into gdpr conpliance

<haasn>
is there a good way to "enable everything" when building ffmpeg?
<JEEB>
I think that's the default, autodetect is on by default. then of course many external libraries are not under autodetect, so those will have to be enabled in any case.
<haasn>
that's exactly what I find annoying, I have e.g. both harfbuzz and freetype installed but unless I specifically set --enable-libharfbuzz and --enable-libfreetype, e.g. vf_drawtext doesn't get built

fosdem even
<wbs>
Daemon404: he's a speaker
<Daemon404>
ah
<Daemon404>
i thought it was up to the room organizers to do that stuff
<thardin>
elenril: good question
<thardin>
the STF thread is a trainwreck
iive has joined #ffmpeg-devel
<Daemon404>
at least if youre in a trainwreck youd probably die istead of continuing to suffer
<thardin>
oh yeah true
<elenril>
thardin: I'm making a change that causes it to get field rate as timebase and it breaks fate-copy-trac4914
Marth64 has joined #ffmpeg-devel
<elenril>
so I'm wondering how to proceed
<thardin>
it takes st->time_base as EditRate
<thardin>
the question though is what the Correct(tm) thing is to do
<elenril>
the easy way out would be to try avg_frame_rate first, which happens to be set correctly for this test
<Marth64>
mkver: Overall I was able to adapt and use your mpeg2_metadata changes with success. I am still testing with some different material, but (1) do you mind if I send it up as a patch when done? obviously with credit to you (2) my understanding that the BSF API does not allow to set avg_frame_rate (which the muxers I'm using expect), so framerate changes using the bsf cannot be reflected
<Marth64>
at the container level. I can only set the deprecated one in codecpar. Just wanted to confirm if I'm seeing it correctly.
<cone-764>
ffmpeg James Almer master:fa469545ba07: avcodec: move leb reading functions to its own header
<thardin>
nope nope nope don't use avg_frame_rate
<thardin>
go to dungeon
<courmisch>
dungeon are deprecated
<courmisch>
it's caleld high-security jail now
<Marth64>
Matroska muxer looks for it first, then yields to r_frame_rate
<Marth64>
yes but as per the doc "only as a last resort" and matroska muxer doesn't consider it
<thardin>
the EditRate can be anything if I'm not mistaken. but if the essence is not editable in said units then you may or may not be committing an MXF sin
<Marth64>
:(
<elenril>
well yes, it's a last resort for computing timestamps
<thardin>
in principle interlaced video is editable on field level, so I suspect it should be OK. index tables also play a role here
<elenril>
if you want to set timestamps, you should set timestamps
<kierank>
elenril: also check time on fosdem
<kierank>
as everyone seems to be getting it in utc
<kierank>
instead of cet
<elenril>
thardin: what seems to be happening is audio is interleaved too fast
<durandal_1707>
whole idea around FFmpeg is to break the laws
<thardin>
elenril: that does not surprise me
<thardin>
perhaps the muxer expects video dts to increase by 1 each packet
<Daemon404>
the app says 1300 too
<Daemon404>
so is 1200 or 1300 right
<durandal_1707>
so 200k goes away because egos could not decide who will get more coins
<elenril>
durandal_1707: where's your project proposal?
<durandal_1707>
librempeg
<elenril>
go and write one that converts all filters from dicts to side data
<courmisch>
It wouldn't be a fair competition, so I won't apply!
<elenril>
I thought you won't apply because you're employed and don't have the time
<Daemon404>
i thought he needed puppy food money
<durandal_1707>
still need it
<Marth64>
elenril: use case: 29.97(soft telecine) -> 23.98(progressive) with modified mpeg2_metadata bsf. mpeg2_metadata allows to set mpeg2 header level framerate, but BSF API only allows to reflect this at codecpar level. The problem then is matroska muxer will write the stream as 29.97 because it doesn't care about codecpar->framerate. if I go to intermediate headerless format like
<Marth64>
mpeg-ps(vob) this is not an issue but then going to ancient limited format
<Marth64>
(also thank you for your time)
<thardin>
I guess mxf_interleave() and mxf_interleave_get_packet() are related. those functions seem new
<elenril>
Marth64: the caller should also propagate the updated framerate to the muxer, which I imagine does not happen properly
<thardin>
2021
<courmisch>
Daemon404: I don't own any canine
<Marth64>
elenril: yes exactly i had to hack it on into ffmpeg_mux as a proof of concept
<elenril>
Marth64: I mean it's not a fundamental issue
<courmisch>
all the monies should go to Kostya to port FFmpeg to Rust anyway
<elenril>
but the code that does it is a bit insane
<Marth64>
got it... i will study more what's going on based on your feedback. will articulate here what i find. thank you!
<elenril>
thardin: 8360fd26105?
<Traneptora>
Lynne: the problem here is the statement "side data must be flat"
<elenril>
Marth64: definitely don't look at avformat_transfer_internal_stream_timing_info(), it will fry your brain
<durandal_1707>
not round or sphere?
<Traneptora>
linking in an external library to serialize it so we can work around our own restriction seems like a problem we created
<elenril>
the thing I'm discussing with thardin is because I made a tiny change to it and now random things explode
<Marth64>
elenril: brain fried just from the name of the function :D
<thardin>
hum hum
<elenril>
it should not exist, as far as I'm concerned
<elenril>
but getting rid of it is...involved
<elenril>
we're getting there though
<thardin>
last time I looked at how interleaving is done I decided to stop looking at how interleaving is done
<elenril>
that code offends me, because it's one of the only two users of .interleave_packet
<Lynne>
Traneptora: you would just assemble all exif data into a cbor data chunk, and provide that chunk as side data, which you would just ask the user to interpret
<elenril>
self.stab(courmisch)
<thardin>
that needs an av_rescale I suspect
<Traneptora>
if the plan was to do that, then I'd just take the Exifdata out of the bitstream directly
<courmisch>
elenril: borrow checker says you can't do that
<Traneptora>
and not process it
<durandal_1707>
how much elenril writes lines of code per hour?
<elenril>
durandal_1707: preferably negative
<Traneptora>
since Jpeg app1, png, and webp all use the same structure
<Traneptora>
tiff is the only exception and it's only because it inherits the endianness from the parent tiff, which you could replicate
<durandal_1707>
since when elenril wrote anything constructively new and useful?
<elenril>
thardin: shouldn't mxf support pts!=dts?
<Traneptora>
code maintenance is god's work
<thardin>
elenril: it does
<thardin>
try commenting out that line entirely. I don't see why it's modifying pts and dts at all
<elenril>
[mxf @ 0x5627f1ac9a80] Received non-video packet before header has been written
<durandal_1707>
bug
<thardin>
I also suppose we don't have any mxf tests that write B-frames
<thardin>
I know for sure I implemented the index table stuff for it and that it worked. but that was way before 2020
<Lynne>
Traneptora: sure, that sounds fine
<elenril>
actually nothing in there seems to read pkt->pts
<Lynne>
are there libraries that can take a pointer with exif and deserialize it?
<thardin>
yeah but doesn't the interleave stuff?
<durandal_1707>
how to make showcwt filter usage popular?
<thardin>
mxf_compare_timestamps()
<elenril>
thardin: inteleaving is by dts
kurosu has quit [Quit: Connection closed for inactivity]
<thardin>
right
<thardin>
wait a minute
<elenril>
usleep(60000000);
<thardin>
oh yeah it does some on-the-fly index generation. it's in mxfdec that my stuff is
<Marth64>
no av_usleep?
<courmisch>
av_this av_that
<Marth64>
haha
<courmisch>
was somebody a glib developer or an Apache HTTPd's ?
<thardin>
yeah it parses that info directly from the essence data
<durandal_1707>
what is needed to make somebody code the fastest FFT/RDFT code in TX with SIMD for x86?
<Marth64>
courmisch:a long time ago i did apache work but i am talking httpd 1.3 days
<thardin>
hence why it doesn't need proper pts or dts. it just digs out the temporal_ref info directly from the mpeg2 headers (and similarly with h264 etc)
<courmisch>
Marth64: so ap_this ap_that time
<elenril>
disgusting
<Marth64>
yes, definitely was a thing haha
<elenril>
thardin: shouldn't there be a place in mxf structures to store timestamps?
<courmisch>
I remember seeing it back when I was an edgy teenagers
<courmisch>
s/s$//
<Marth64>
CGI for all
<durandal_1707>
what is needed to make somebody code the fastest FFT/RDFT code in TX with SIMD for x86?
<Traneptora>
Marth64: av_usleep_now_goodnight
<thardin>
elenril: there is
<Marth64>
+_q
<thardin>
it's similar to cts in mov
<elenril>
but our muxer does not use it?
<thardin>
it doesn't actually store the timestamps themselves, but pts - dts
<durandal_1707>
nobody wants to write and do proposal for TX to make use of 200k
<thardin>
see section 11.1.6 of S377m
<elenril>
durandal_1707: speedups are not maintenance
<durandal_1707>
:((((
<elenril>
thardin: is it downloadable?
<thardin>
I could email it to you
<thardin>
and hey, the example there is with interlacing
<elenril>
that would be nice
<thardin>
temporal offsets like 0,0,+2,+2,+2,+2,-4,-4,+2
<durandal_1707>
ban all the people
<thardin>
elenril: sent
<durandal_1707>
i got elenril's shelter address!
<thardin>
either way seems we need to make sure we have a long-GOP MXF test. with open and closed GOPs
<elenril>
thanks
<thardin>
helpfully you can point the entries for both fields to the same body offset
<elenril>
now the question still is how do i proceed
<thardin>
based on what S377m says it seems the correct action is to write two entries per packet when the input is interlaced
<thardin>
I'd add very stringent checks in mxf_init()
<elenril>
I don't think it even is here
<elenril>
it just might be, so ffmpeg.c decides to use the field rate as the framerate
<elenril>
err as the timebase
<thardin>
seems like you should get a "missing frames" warning if you mess up
<thardin>
maybe.
<thardin>
I bet mxf_parse_mpeg2_frame() is slower than it needs to be
<thardin>
it parses the entire packet byte by byte
<courmisch>
also that's the whole premise of Villainess Level 99

durandal_1707, do you take card?
<cworley>
one thing that is unclear as a newcomer is what it takes to get patches reviewed and merged, besides the whim of someone with write access

lots of time
<Marth64>
and very kind people willing to take a chance with strangers

why LibAV still uses mailing lists?

fear of patents and such

Marth64: 24h migration sounds like a great experience
<Marth64>
JEEB: it was awful but we did it with Bash and Groovy. GitLab had good APIs to work with.
<JEEB>
nice :)
<durandal_1707>
it was miracle that FFmpeg switched to git
<JEEB>
also I probably have a SMF instance backed up somewhere here which I need to pull back up or switch to some other thing that has migrations from SMF
<Daemon404>
it was done as part of the fork

only way to force Certain People

no, no squash, rebase and merge
<durandal_1707>
what that means?
<durandal_1707>
you merge all commmits into 1?
<jamrial>
squash? yeah
<wbs>
yes, each PR/MR becoms 1 commit afterwards
<wbs>
so your branch is commit 1, "libavcodec: implement decoder x", commit 2 "fix bug", commit 3 "fix typo", etc
<durandal_1707>
hack
<Marth64>
git rebase -i HEAD~<how far back you wanna go>
<jamrial>
yeah, some projects add new commits to the MR with fixes reported during review, and then that gets squashed into a single commit
<wbs>
some projects do this, because github's UI for tracking what changed from one revision of a PR to the next, absolutely sucks
<jamrial>
yeah, gitlab is great with that
<JEEB>
I think github finally added links for those comparisons nowadays
<jamrial>
you can see actual line changes between force push on the same MR
<wbs>
which makes it much harder to merge a branch of intentionally-separate commits, as you'd need to do one PR per intended commit
<wbs>
it's absolute madness
<JEEB>
so you see have a link for each push
<JEEB>
(at least force push)
<durandal_1707>
"Fixed one lack"
<Marth64>
i will say one annoyance with gitlab was server maintenance
<jamrial>
it does however not filter commits added from a rebase to current git head
<Marth64>
like it wasn't horrible but you need to pay attention on disk space, where things are blowing up due to logging/caching/whatever. you need also to deal with ruby
<Marth64>
circa 2018 at least idk if ruby is out of the picture now
<JEEB>
Marth64: videolan already does gitlab maintenance so I believe we could either share those resources/instance, or otherwise get someone to properly manage various bits of the infra
<wbs>
Marth64: that would require a 100% rewrite of gitlab, that's not happening
<Marth64>
JEEB: perfect good i think thats my only point, it needs a good admin or group of
<Marth64>
gitlab ci/cd is nice too but you need docker skillz
<Marth64>
wbs: ah well

"We love transparency in this project, right?" since when?
<Daemon404>
swscale supported alpha for ages
<durandal_1707>
lol
<j-b>
Daemon404: gg
<wbs>
Daemon404: alpha the architecture, or as in transparency? :P
<wbs>
ah, now I see the reference to the line above, doh
<Daemon404>
lol
<durandal_1707>
rotfl
<Marth64>
lasagna, ravioli, or spaghetti
<Daemon404>
is this like the pasta version of bikeshedding?
<jamrial>
wbs: i was about to say it supported both, but i just noticed that no, there's no alpha asm in sws
<durandal_1707>
pasta version is irrelevant, the red thing that goes in is more important.

According to clinical research, Red 40 can cause hypersensitivity reactions—exaggerated or inappropriate immunologic responses to an antigen or allergen. While these reactions vary in nature, one commonly reported hypersensitivity reaction is ADHD. Cancer-causing carcinogens like benzidine have also been identified as contaminants in Red Dye 40.

Merge FFmpeg Forks
<kierank>
what fork?
<kierank>
12 months work?
<durandal_1707>
Librempeg is upstream of FFmpeg
<Daemon404>
kierank, ... sdr
<kierank>
durandal_1707: lol not this again
<durandal_1707>
yes, ffmpeg can now merge SDR, but librempeg will not pick it.
<Daemon404>
i am not joking here
<Daemon404>
sdr is probably the fork they mean
<Daemon404>
but didnt want to write sdr
<durandal_1707>
i'm really serious
<jamrial>
sdr is not being merged unless it's its own library and not a clone of libavdevice using lavf's API
<jamrial>
lavd is already awful to have in its current state, we're not making that same mistake twice
<Daemon404>
i know, im just referring to the trac wiki
<Daemon404>
not reality
<durandal_1707>
ugh, why libpostproc is still there?
<Daemon404>
mpeg-1 vcds are important
<jamrial>
durandal_1707: because nobody rewrote the two or so filters that use it
<jamrial>
once that's done, it's gone

Daemon404: added a comment as to what fork
<durandal_1707>
jamrial: are you old? i proposed that last time, and MiNi was against it.
<Daemon404>
i was hoping to hold out till the technical meeting
<jamrial>
durandal_1707: how so?
<Daemon404>
to put my foot back in the poo
<jamrial>
if no filters use the library, then it can be removed
<durandal_1707>
MiNi wrote something like people wanting use only libpostproc library and nothing else
<jamrial>
[doubt]
<durandal_1707>
there is whole transcript
<durandal_1707>
it was on one of those video link meettings
<jamrial>
people actually used libavresample, but we removed it anyway because we already had another resampling library
<durandal_1707>
mainly no resolution came out so nothing happened
<jamrial>
so libpostproc has no reason to be in git head if lavfi features its functinoality
<jamrial>
simple as
<durandal_1707>
jamrial: well, avresample had better looking source code, everything else was very similar.
ccawley2011 has joined #ffmpeg-devel
<durandal_1707>
i need to check this again, because if similarity is soo huge, either one coder stole it from another; they coded it together; or both stole it from someone else...
<durandal_1707>
lol, 50.000 eur to merge some commits from SDR or librempeg(i sincerely hope) into ffmpeg

the false positive is a very real problem with these types of tools
<Marth64>
you have to absolutely tune them
<Marth64>
one of my teams was bombarded with stupid asks from a similar tool after an update
<Marth64>
"you are using variable with the word __xyz__ in it, rewrite all your code or die"
<Marth64>
its worse when you have to argue it with actual people who have no idea how the static analyzers work and how the code works
<Marth64>
but, is a neccessity for modern secure code
<Daemon404>
semgrep by default will flag any C function call with alloc in the name
<Marth64>
yes and they'll rack up the count of how many you have, which serves no purpose other than to make you look bad on reports to your stakeholders
<Marth64>
a simple "hey, you're doing this, are you ok with it" would be fine for something like that
