[00:06] <pross-au> Compnn: thanks. i will pass on to michael m.

[01:01] <llogan> saste: "duration specification" might be unclear for some users.
[01:02] <saste> llogan, what do you suggest?
[01:06] <llogan> saste: a variation of "must be a number in seconds, or sexagesimal format hh:mm:ss[.milliseconds]" perhaps. it's a lot more verbose though. tradeoffs.
[01:07] <saste> llogan, no, because i don't want to update the whole manual if the syntax changes
[01:09] <llogan> good point
[01:10] <saste> originally it was taking an int (number of seconds, unspecified in the docs)
[01:10] <saste> then i extended to take a duration specification, which is more flexible
[01:10] <llogan> a good improvement
[01:10] <saste> i could point to the ffmpeg-utils manuals, but i should do that in at least three different points
[01:11] <llogan> nah. it was just thinking out loud more than anything.
[01:11] <saste> so i'm rather supposing that the user knows what is a duration specification (which is not a valid assumption, but good for me)
[01:13] <llogan> s/it/I
[01:36] Action: ubitux is still alive
[01:37] <ubitux> gtg, cya
[01:37] <beastd> Hey ubitux
[01:40] <ubitux> actually i have 5 more minutes
[01:40] <ubitux> hey beastd 
[01:40] <ubitux> how is the subtitles encoding going on?
[01:42] <beastd> Nicolas never replied on my 2nd mail AFAICT. So I will try to code a POC now and hope Nicolas will be happy with it :)
[01:43] <beastd> ubitux: I try to get it done before you come back. So you can work on the next task once you returned ;)
[01:44] <llogan> ubitux: are you traveling?
[01:44] <ubitux> beastd: harass him!
[01:44] <ubitux> llogan: yup
[01:45] <ubitux> llogan: around here: http://lucy.pkh.me/checkpoint.jpg
[01:46] <ubitux> and now gtg for good, see you
[01:46] <beastd> ubitux: have fun!
[02:25] <hyc> 'morning
[02:27] <hyc> anyone up for an algorithm puzzle? I've got some C code that was reverse-engineered from an obfuscated binary.
[02:27] <hyc> I believe it's an obfuscated implementation of something like HMAC MD5
[02:27] <hyc> but haven't been able to identify for certain
[02:29] <hyc> would like to have a clean generic version of it, since this code does a lot of misaligned accesses. it would never run on sparc, only x86.
[02:40] <cone-746> ffmpeg.git 03Michael Niedermayer 07master:d7a46ca179e4: sws: add AVOption flag for error diffusion dither
[02:40] <cone-746> ffmpeg.git 03Michael Niedermayer 07master:ca447592b18a: sws: rgb/bgr 4/8 error diffusion dither
[02:40] <cone-746> ffmpeg.git 03Michael Niedermayer 07master:8045c0167dbe: sws: Only reset dither state for bitexact mode
[02:40] <cone-746> ffmpeg.git 03Michael Niedermayer 07master:2dc2e4f5af7a: sws: Enable full chroma resolution when needed for ED dither
[02:56] <burek> if anyone is idle enough to check the new fate interface, you can see it here: http://ffmpeg.gusari.org/fate2/
[02:56] <burek> though, there's only 1 machine in the test folder, because folders were too big to just copy/paste to the test machine
[03:02] <michaelni> burek, 0 Tests ?
[03:03] <burek> 0 errors in tests
[03:03] <burek> need to correct the title
[03:07] <burek> fixed
[03:08] <burek> when you click on the machine name, you get the history of its uploads
[03:08] <burek> where you can check diff between each 2 subsequent uploads
[03:08] <burek> among other logs
[03:09] <cbsrobot> burek: not sure if I like the overlays, but they should at last have a onmouseout timout 
[03:10] <burek> I agree
[03:10] <burek> I'll add that, though you can ctrl+click anyway, to get the content in a new page
[03:11] <cbsrobot> and show the +- only if there is a difference ...
[03:11] <burek> that way I would have to do diff for all the items
[03:12] <burek> this way i do it only on mouse over
[03:12] <burek> it saves cpu
[03:12] <cbsrobot> it's just an idea &.
[03:12] <cbsrobot> i know nothig about the internals &.
[03:16] <burek> :beer: :)
[03:16] <burek> thanks :)
[03:17] <cbsrobot> and once looking at one machine, the "machine" row is not needed anymore
[03:18] <burek> I agree, but then i have to write another css file just for that page :) i'll see if i can just hide that column through css or something :)
[03:18] <cbsrobot> I just give some ideas - take what you want ...
[03:19] <burek> ok
[03:36] <michaelni> burek, 0 failed tests but how many tests did run ?
[03:36] <michaelni> this matters too
[03:36] <michaelni> if 0 tests are run for example :)
[03:37] <hyc> lol

[17:28] <durandal_1707> michaelni: you know some nice cuve(s) [0,1] <-> [0,1] ?
[17:57] <michaelni> durandal_1707, whats nice ? x=y ?
[19:57] <durandal_1707> michaelni: nice is something more spiral like sin/cos
[20:00] <durandal_1707> ie something like half sin() but more like rotated S
[20:00] <durandal_1707> otherwise sin looks more like x=y
[20:48] <michaelni> durandal_1707, no clue what you are after but a parametric function within 0,1 that looks nice and has sin in it is sin(t*77)/2+.5,cos(t*101)/2+.5
[20:49] <michaelni> to see it in gnuplot "set parametric ; set samples 10000 ;  plot sin(t*77)/2+.5,cos(t*101)/2+.5"
[20:50] <Daemon404> michaelni, btw, i purposely havent applied those tablegen fixes, since a certain someone is opting to write proper host tools dep checks / headers
[20:50] <Daemon404> just so you dont ask
[21:04] <kierank> durandal_1707: are you going to fosdem
[21:06] <durandal_1707> kierank: if you payme personal aircraft and body-guards + ....
[21:07] <kierank> why
[21:07] <durandal_1707> i think i cant go anywhere without visa, say until 2015 or so?
[21:11] <Daemon404> some sort of country-specific thing?
[21:13] <durandal_1707> kierank: i see nothing interesting of fosdem site...
[21:13] <durandal_1707> s/of/on
[21:13] <durandal_1707> Daemon404: i dont have passport...
[21:14] <Daemon404> you cant get one?
[21:15] <durandal_1707> :effort
[21:23] <kierank> anyway i know people here don't believe me but meeting in person is not as bad as you imagine
[21:24] <wm4> even if it's a libav dev? (or ffmpeg dev vice versa)
[21:26] <kierank> mostly yes
[21:28] <durandal_1707> kierank: i see nothing related to multimedia on fosdem
[21:29] <kierank> it is more of a social thing
[21:29] <Daemon404> you can go and ahrras poettering
[21:29] <Daemon404> harass*
[21:29] <llogan> what kind of beer will be on tap?
[21:30] <wm4> why harass the guy who makes the linux desktop a reality
[21:30] <Daemon404> is that a joke?
[21:30] <Daemon404> :|
[21:30] <durandal_1707> s/reality/nightmare
[21:30] <Daemon404> ^
[21:30] <wm4> it's both a joke and the truth
[21:32] <kierank> llogan: crazy belgian beer
[21:32] <kierank> 10% stuff
[21:34] <llogan> sounds good.
