[03:07:13 CEST] <atomnuker> turns out that ff_lpc_init() does not reserve a big enough buffer to calculate autoc coefficients of over 750 samples

[14:33:38 CEST] <Daemon404> i gotta say, i think ffmpeg should probably blend as prores normally does.
[14:33:41 CEST] <Daemon404> by default
[14:33:52 CEST] <Daemon404> mind you i lack context of the previous battles.
[14:34:51 CEST] <Daemon404> but i do know we get random complaints about it at work
[14:45:01 CEST] <wm4> holy shit, 23 comments
[14:45:14 CEST] <wm4> oh mine was 22th
[15:15:32 CEST] <Daemon404> wm4, youre fightign a losing battle
[15:15:36 CEST] <Daemon404> you know how "special" carl is
[15:15:47 CEST] <Daemon404> once he has decided it should be closed, it doesnt matter if it really should be
[15:24:07 CEST] <wm4> I know, but there must be a way
[15:24:20 CEST] <Daemon404> no not really
[15:24:40 CEST] <Daemon404> ive never seen it happen
[15:25:06 CEST] <Daemon404> lmao
[15:25:08 CEST] <Daemon404> that last reply
[15:25:09 CEST] <Daemon404> gold.
[15:25:20 CEST] <wm4> yes that's pretty good
[15:26:17 CEST] <wm4> ok posted too... another 10 seconds of my life wasted
[15:27:13 CEST] <kierank> shall I ban carl temporarily
[15:28:31 CEST] <Daemon404> wm4, for comparison: there was one bug where ~4-5 otehr devs said carl was in the wrong, it didnt hel[
[15:28:34 CEST] <wm4> if you can do that and if he closes it again why not
[15:28:34 CEST] <Daemon404> help*
[15:28:51 CEST] <Daemon404> in the end, michaelni mailed him, but nothing changed.

[15:57:57 CEST] <durandal_170> Daemon404: which bug?
[16:01:19 CEST] <ubitux> 4746
[16:01:29 CEST] <Daemon404> i think durandal_170 was askign about the one i reference
[16:01:30 CEST] <ubitux> ah, another one, my bad
[16:01:33 CEST] <Daemon404> which was quite a while back
[16:01:37 CEST] <Daemon404> (i dont remember which0
[16:01:57 CEST] <ubitux> hey, does anyone knows a community dedicated to adobe reversing? :P
[16:14:38 CEST] <kierank> ubitux: adobe what?
[16:14:42 CEST] <cone-042> ffmpeg 03Sven Dueking 07master:67e87f8050cb: avcodec/qsv : Added look ahead rate control mode
[16:14:48 CEST] <ubitux> kierank: typically photoshop
[16:19:16 CEST] <Daemon404> wut
[16:23:40 CEST] <durandal_170> ubitux: ida
[16:23:52 CEST] <ubitux> yeah that's not exactly a community
[16:24:20 CEST] <Daemon404> thats a weridly specific thing to have a community about
[16:24:43 CEST] <ubitux> well, there are many niche reverse communities
[16:25:30 CEST] <Daemon404> i havent seen one for a specific vendor
[16:29:05 CEST] <ubitux> you have them for games typically
[16:33:58 CEST] <Daemon404> games are special
[16:34:02 CEST] <Daemon404> they have devoted fanbases
[16:39:42 CEST] <ubitux> and no fan of photoshop?
[16:39:44 CEST] <ubitux> :s
[16:40:47 CEST] <Daemon404> i dont think you quite understand.
[16:41:16 CEST] <Daemon404> nobody has nostalgic memories of photoshop, to the same extent of $love_game 
[16:41:31 CEST] <Daemon404> loved*
[16:41:52 CEST] <Daemon404> nor would they need to RE to keep it alive
[16:42:00 CEST] <ubitux> :(
[16:45:58 CEST] <durandal_170> ubitux: what does this black slider do?
[16:46:05 CEST] <ubitux> i don't know :(
[16:46:29 CEST] <ubitux> it's the K parameter of the the CMYK settings
[16:46:46 CEST] <ubitux> i'm able to have a working mixture of CMY and a standalone K
[16:47:02 CEST] <ubitux> but i can't figure out how to make both of them work at the same time
[16:48:17 CEST] <durandal_170> so you have results but need function?
[16:48:44 CEST] <ubitux> yeah, kind of
[16:49:23 CEST] <ubitux> it's a pain to make pages of data result
[16:49:43 CEST] <ubitux> notably bc i couldn't find a way to keep the color grab window open while doing other shit
[16:50:11 CEST] <Daemon404> what exactly are you trying to do
[16:50:26 CEST] <ubitux> understand the K (black) slider in selective color
[16:50:50 CEST] <ubitux> see http://ffmpeg.org/pipermail/ffmpeg-devel/2015-August/177224.html
[16:51:00 CEST] <ubitux> ^F FIXME
[16:53:16 CEST] <iive> ubitux: k stands for blacK
[16:53:32 CEST] <ubitux> yeah right i figure that out so far :p
[16:55:11 CEST] <iive> what is to figure out about it?
[16:55:56 CEST] <Daemon404> [15:46] <@ubitux> i'm able to have a working mixture of CMY and a standalone K <-- ?
[16:56:00 CEST] <Daemon404> you dont 'mix' cmy
[16:56:15 CEST] <ubitux> i mean user setting of C, M and Y at the same time
[16:56:21 CEST] <ubitux> that works well so far
[16:56:33 CEST] <ubitux> and the K slider standalone without changing C, M or Y
[16:56:46 CEST] <ubitux> but not CMY + K
[16:56:46 CEST] <iive> cmyk is palette that is based on colors used for printing. you can go without black, but you'd have to use excessive quantities of the other colors
[16:57:00 CEST] <iive> ubitux: it's like RGB+Gray
[16:57:33 CEST] <ubitux> except adding K to either the CMY or the final RGB adjustement doesn't seem to be in the same PS scale
[16:58:02 CEST] <Daemon404> ubitux, there is no definitive way to handle this afaict
[16:58:07 CEST] <Daemon404> unless your goal is 'do what ps does' only?
[16:58:27 CEST] <Daemon404> (also, above: carl being his usuall idiotic self)
[16:58:48 CEST] <ubitux> yes i want to do what ps does exactly
[16:59:03 CEST] <ubitux> notably because i support the PS preset files
[16:59:08 CEST] <Daemon404> i see
[16:59:21 CEST] <Daemon404> as an aside, handling cmyk in ffmpeg seems of little value
[16:59:26 CEST] <Daemon404> in terms of filtering
[16:59:36 CEST] <Daemon404> it's a thing used for print
[16:59:58 CEST] <Daemon404> (andt he fact that people distribute e.g. cmyk jpegs on the web is just people being silly)
[17:00:03 CEST] <iive> film is not printed, is it?
[17:01:01 CEST] <ubitux> Daemon404: the filter is useful to apply a color transformation to a certain range of colors
[17:01:38 CEST] <Daemon404> iive, i can se it now... halftone'd film
[17:01:40 CEST] <Daemon404> glorious
[17:01:41 CEST] <Daemon404> see*
[17:02:00 CEST] <Daemon404> ubitux, how is it useful though
[17:02:06 CEST] <Daemon404> isnt such a filter generally used to prepare prints
[17:02:30 CEST] <ubitux> "the blue of the sky is too powerful, let's make it a bit more dull"
[17:02:39 CEST] <ubitux> "the red of the sun doesn't radiates enough, let's boost it a bit"
[17:02:41 CEST] <ubitux> etc
[17:02:54 CEST] <Daemon404> wouldnt one generally use HSV then
[17:02:57 CEST] <Daemon404> and not CMYK
[17:02:59 CEST] <Daemon404> to adjust
[17:03:16 CEST] <ubitux> CMYK is just the user settings, not the target
[17:03:26 CEST] <Daemon404> i know
[17:03:30 CEST] <Daemon404> thats what im saying.
[17:03:43 CEST] <Daemon404> you'd generally fiddle with H, S, and V, no?
[17:03:53 CEST] <ubitux> it doesn't really matter if for the user it's expressed as CMYK or HSV or whatever
[17:04:00 CEST] <ubitux> i just stick with PS layout
[17:04:17 CEST] <ubitux> it will allow ppl to setup there filter on one frame in PS
[17:04:20 CEST] <ubitux> export the preset
[17:04:22 CEST] <ubitux> and apply to the video
[17:04:28 CEST] <ubitux> just like curves filter
[17:04:49 CEST] <Daemon404> im saying adjusting C, M, Y, and K only makes sense from a user perspective if its intended for print
[17:04:57 CEST] <Daemon404> (someone feel free to correct me)
[17:05:01 CEST] <ubitux> http://xolexo.deviantart.com/art/Selective-Color-Presets-for-Photoshop-345687223
[17:05:03 CEST] <Daemon404> im saying you have a XY problem.
[17:05:09 CEST] <ubitux> you have some examples of presets here typically
[17:05:34 CEST] <ubitux> well, CMYK is understandable from a user perspective as well
[17:05:38 CEST] <ubitux> it's pretty fine as an interface
[17:05:42 CEST] <Daemon404> clearly not
[17:05:44 CEST] <Daemon404> as you failed
[17:05:45 CEST] <Daemon404> ;)
[17:05:56 CEST] <ubitux> yeah well, the devil is in the details for K
[17:06:29 CEST] <ubitux> but saying "i'll increase yellow, reduce cyan, and make red areas a little darker" is prefectly understandable from a user perspective 
[17:06:42 CEST] <Daemon404> and K?
[17:07:14 CEST] <Daemon404> anyway
[17:07:16 CEST] <Daemon404> aside from that
[17:07:34 CEST] <Daemon404> i was going to suggest looking in gimp, but i guess gimp is too crappy to have such a thing
[17:07:38 CEST] <Daemon404> maybe krita
[17:07:49 CEST] <ubitux> yeah i didn't find any tool implementing it
[17:08:52 CEST] <Daemon404> wm4, youve just assured that carl will now close all your bugs as soon as you open them.
[17:09:00 CEST] <JEEB> :D
[17:09:14 CEST] <Daemon404> thats why i stopped using trac fwiw
[17:10:10 CEST] <ubitux> so much drama
[17:10:35 CEST] <wm4> trollol
[17:14:31 CEST] <wm4> so what's this actually about
[17:14:41 CEST] <wm4> that a "slow" libswscale option is not on by default?
[17:14:48 CEST] <wm4> so the classic "slow but wrong is better"?
[17:14:55 CEST] <wm4> err
[17:15:00 CEST] <wm4> "fast but wrong"
[17:18:27 CEST] <wm4> lol
[17:18:58 CEST] <wm4> should start a git revert war
[17:19:04 CEST] Action: wm4 goes back to doing nothing
[17:19:14 CEST] <Daemon404> carl vs the world
[17:19:16 CEST] <Daemon404> as per usual
[17:19:18 CEST] <Daemon404> mvoe along folks
[17:28:32 CEST] <Daemon404> i feel bad for the bug reporter.
[17:34:47 CEST] <wm4> ok I sent a patch
[18:04:29 CEST] <cone-042> ffmpeg 03Ganesh Ajjanagadde 07master:0169c4dc818b: avfilter/vf_separatefields: use the name 's' for the pointer to the private context
[18:24:34 CEST] <ubitux> Daemon404: you mean koda?
[18:24:52 CEST] <Daemon404> is that who it is?
[18:24:56 CEST] <ubitux> yes
[18:25:04 CEST] <Daemon404> 50 bucks says carl is being vindictive cunt then
[18:25:14 CEST] <Daemon404> grudge shit
[18:26:19 CEST] <JEEB> lol
[18:26:47 CEST] <Daemon404> i am sadly not joking
[18:36:43 CEST] <durandal_170> what about koda?
[18:54:13 CEST] <kierank> if he closes it again i think it should be ban time
[18:56:09 CEST] <Compn> carl is the top bug trac dev
[18:56:22 CEST] <Compn> banning him would be shooting the project in its face
[18:56:29 CEST] <Daemon404> bullshit
[18:56:29 CEST] <kierank> temporary ban
[18:56:32 CEST] <Daemon404> "dev"
[18:56:48 CEST] <Daemon404> if you mean curator, then maybe.
[18:57:11 CEST] <Compn> carl has posted patches that fix bugs and those patches have been reviewed and committed
[18:57:25 CEST] <Daemon404> those are rarely fixes
[18:57:27 CEST] <Compn> this is a fact, but feel free to be angry at him for closing some bugs
[18:57:30 CEST] <Daemon404> theyre one line changes that hack shit in
[18:57:35 CEST] <Daemon404> and break stuff half the time
[18:57:56 CEST] <kierank> Compn: he's repeatedly closing the bug
[18:58:05 CEST] <Compn> just leave it closed and bookmark it then
[18:58:06 CEST] <kierank> when numerous devs are telling  him not to
[18:58:11 CEST] <Daemon404> Compn, thats not a solution
[18:58:14 CEST] <Compn> the status of the bug does not matter in the grand scheme of reality
[18:58:17 CEST] <Daemon404> thats letting the petualant child have his way
[18:58:19 CEST] <Daemon404> to keep the peace
[18:58:19 CEST] <Compn> yes, it is the best solution
[18:58:20 CEST] <wm4> lol
[18:58:34 CEST] <Daemon404> in fact, a number of us here do nto submti bugs to trac
[18:58:36 CEST] <Daemon404> because of carl
[18:58:39 CEST] <Compn> i know
[18:58:43 CEST] <Daemon404> "solution" my ass.
[18:58:45 CEST] <kierank> that's a disgusting attitude
[18:58:48 CEST] <Daemon404> yes it is
[18:59:00 CEST] <wm4> you can bet users aren't fond of this treatment either
[18:59:02 CEST] <Compn> why not post bugs to libav tracker then
[18:59:08 CEST] <kierank> this project has the maturity of a 2 year old
[18:59:27 CEST] <Daemon404> Compn, "but libav is dead" is not a valid reason to endorse shitty behavior
[18:59:42 CEST] <Daemon404> thats like saying "cmon let me cut you! over at libav they'd shoot you, so we're fine"
[19:00:09 CEST] <Compn> what
[19:00:21 CEST] <Compn> i was just suggesting to use their tracker for bugs for people who dont like carl
[19:00:25 CEST] <Compn> since carl does not have power there :P
[19:00:33 CEST] <Daemon404> Compn, libav bugtracker is akin to throwing bugs in a hole
[19:00:37 CEST] <Daemon404> it's a no-op.
[19:00:53 CEST] <Timothy_Gu> <+kierank> if he closes it again i think it should be ban time <-- +1, at least temporarily
[19:00:57 CEST] <kierank> what a state of affairs this project is in when you are happy to accept antisocial behaviour
[19:01:11 CEST] <Daemon404> kierank, there's a term for it. it's called the status quo.
[19:01:14 CEST] <Daemon404> you may have heard of it.
[19:01:14 CEST] <Compn> kierank : no offense, but i see anti-social behavior from many devs in this project.
[19:01:35 CEST] <kierank> right, so many wrongs make a right
[19:01:41 CEST] <kierank> superb logic
[19:01:48 CEST] <Compn> no
[19:01:54 CEST] <Compn> i'm just trying to keep the project together
[19:02:02 CEST] <Compn> you start banning people and they start dissapearing
[19:02:19 CEST] <kierank> or they change their ways and act like adults
[19:02:25 CEST] <Daemon404> you have to have SOME way to enforce reaosnable beahvior
[19:02:29 CEST] <kierank> if they cant do that then perhaps they should bugger off
[19:02:36 CEST] <kierank> vlc had problems in this area and they were dealt with
[19:02:55 CEST] <Timothy_Gu> also another example& michael
[19:04:05 CEST] <Daemon404> it's possible michael, aside from needing time off, has resigned because he doesnt want to deal with the childish antics of teh community at large.
[19:04:21 CEST] <Daemon404> (i do not speak for anyone. just speculation.)
[19:04:42 CEST] <iive>  It's easier to see the straw in someone else than the beam in oneself
[19:14:47 CEST] <durandal_170> carl wrote caf muxer, so its not only patches...
[19:17:56 CEST] <Daemon404> 0
[19:23:48 CEST] <durandal_170> what 0?
[19:23:54 CEST] <Daemon404> was an accident
[19:36:29 CEST] <durandal_170> ubitux: could you plot data you have?
[19:52:36 CEST] <ubitux> durandal_170: most of the K related stuff is on a white board, i probably need to complete them and write them down in a formal way
[19:52:52 CEST] <ubitux> it's hard to guess what kind of data will be relevant though
[20:13:56 CEST] <kierank> Timothy_Gu: temporary ban carl?
[20:16:40 CEST] <BBB> cehoyos must understand that his opinions cannot possibly taken for law just by fact of it being him alone?
[20:16:53 CEST] <BBB> I mean, if he was right, that would be one thing, but this...
[20:17:10 CEST] <BBB> funny though
[20:17:25 CEST] <BBB> our community is as unhealthy as it ever was and will ever be
[20:17:26 CEST] <BBB> sad
[20:17:30 CEST] <kierank> I'm happy to ban him but I suspect Compn will complain and say he wasn't consulted
[20:19:49 CEST] <wm4> this reminds me that we don't have a real decision making process in ffmpeg
[20:20:10 CEST] <kierank> no shit
[20:20:13 CEST] <kierank> it was dictatorship before
[20:20:22 CEST] <wm4> (still is)
[20:20:31 CEST] <wm4> this group of certain core devs is like a wall
[20:20:32 CEST] <BtbN> File a bug about carl not behaving.
[20:20:34 CEST] <wm4> can't overrule them
[20:20:45 CEST] <wm4> BtbN: edit war: the ticket?
[20:21:12 CEST] <wm4> (and by "core devs" I don't mean in terms of contributions)
[20:21:31 CEST] <BtbN> I have seen that actualy happening a few times, in various projects. It's not neccesarily ment as a joke.
[20:23:21 CEST] <wm4> well, at least we don't have commit revert wars
[20:27:05 CEST] <Timothy_Gu> kierank: yes
[20:27:33 CEST] <kierank> I am nervous about doing this
[20:28:17 CEST] <wm4> in his logic, he rejected the patch, which justified closing the issue
[20:28:28 CEST] <wm4> makes perfect sense huh
[20:33:31 CEST] <ubitux> kierank: beware of getting classified as one of the traitors etc
[20:34:05 CEST] <kierank> I don't particularly give a shit whether I am a traitor/thief/liar/swine etc
[20:54:47 CEST] <iive> I think the default behaviour should be blending with checkboard texture
[20:55:04 CEST] <iive> this way it would be both black and white.
[20:55:21 CEST] <iive> also, so does photoshop :)
[21:03:18 CEST] <wm4> still better than just discarding alpha
[21:10:56 CEST] <iive> then it is decided!
[21:13:36 CEST] <durandal_170> no, i want it in pink
[21:14:41 CEST] <wm4> can the blend color be set?
[21:25:33 CEST] <durandal_170> not yet
[21:40:16 CEST] <iive> durandal_170: checkboard pattern on pink and yellow!
[21:41:56 CEST] <durandal_170> yes there are many possibilities
[21:44:14 CEST] <iive> gold and blue?
[22:34:06 CEST] <Compn> [14:20] <wm4> this group of certain core devs is like a wall
[22:34:10 CEST] <Compn> who is a core dev btw ?
[22:34:35 CEST] <Compn> because i dont include myself as one.
[22:34:51 CEST] <Compn> why you  guys listen to me as if i have any say around here is strange...
[22:35:19 CEST] <Compn> but i hope you listen to my advice at least and do not ignore me like some people have before
