[00:01] <ubitux> saste: i didn't have a look yet to the last showwaves
[00:02] <ubitux> but don't wait for me :p
[00:08] <saste> ubitux: waiting for nicolas reply, maybe i'll ping the patch
[00:08] <ubitux> :)
[00:08] <ubitux> anyway, it seems ppl really wants me to use AVPacket in the subtitles API
[00:09] <saste> ppl always want something from you
[00:10] <ubitux> i can only give love
[00:10] <ubitux> and compassion
[00:14] <saste> and patches
[00:15] <ubitux> ah true, almost forget those
[00:58] <ubitux> http://ffmpeg.org/ffmpeg.html
[00:58] <ubitux> new documentation layout @_@
[01:01] <durandal_1707> huh, font is smaller
[01:02] <durandal_1707> and fate page is still awfull ...
[01:03] <ubitux> i don't have control on that :)
[01:04] <ubitux> the fate front must be updated, you should ask baptiste
[01:05] <ubitux> anyway, 'night ppl
[01:13] <llogan> ubitux: looks nice. now i can't hurt myself on those corners.
[01:34] <durandal_1707> what pixel formats is supported by drawutils?
[01:39] <saste> durandal_1707: tools/lavfi-showfiltfmts in case you don't know it
[03:02] <durandal_1707> is there way to set pixel format for vsrc filter?

[05:00] <gnafu> ubitux: Were you the one who told me to watch that one music video?  It was a while ago, so I kinda forgot.
[05:00] <gnafu> I /finally/ got around to watching it just now.
[05:00] <gnafu> Very interesting.
[07:32] <ubitux> gnafu :)
[07:32] <ubitux> DyE?
[09:34] <cbsrobot> ubitux: I know - i know, but what about: http://pastebin.com/ijLbfjXC
[09:46] <ubitux> i really don't mind
[09:46] <ubitux> cbsrobot: can i see a before/after?
[09:50] <cbsrobot> ubitux: do you have firefox and firebug ?
[09:50] <ubitux> i only have firefox
[09:51] <ubitux> oh there is css editor now
[09:53] <cbsrobot> you can change it in firebug - i don't know the css editor
[09:53] <ubitux> shift + f7
[09:53] <ubitux> looks native
[09:54] <cbsrobot> maybe we can remove it alltogether
[09:54] <cbsrobot> but the 0.8 em looks really small on my screen at alst
[09:55] <ubitux> ok ok
[09:55] <ubitux> well send a patch, i'll apply it
[09:55] <ubitux> looks ok to me
[09:55] <cbsrobot> and
[09:55] <cbsrobot> for block text a serif is better suited in my oppinion
[09:56] <cbsrobot> the sans serif is ok for titles and such
[09:56] <cbsrobot> but in typography, when you need to read a lot of text the serif is better suited
[09:56] <cbsrobot> look at your newspaper - it always a serif font
[09:57] <cbsrobot> it makes the website look "web 1.0", but it's better for reading, what is more important to me
[09:59] <ubitux> it looks more readable to me that way
[09:59] <ubitux> less quirks :)
[09:59] <ubitux> but it can be discussed of course
[10:22] <ubitux> wow 3 reviews in a few minutes for the SMPTE bars filter :)
[10:28] <kierank> why are the smpte bars being done full range?
[10:31] <kierank> also the pixel values are defined in 10-bit iirc
[10:57] <cbsrobot> doesn't the pluge signal area need to be in full range ?
[10:58] <cbsrobot> the middle is 0 IRE, left is -4 IRE and right is +4 IRE
[11:10] <TimNich> pluge does, but I don't think the bars should be. but bars witha dash of superblack/superwhite to test range would be good...
[11:17] <TimNich> By super black I mean RGB 000 and super white RGB 255, so that bars 'black' sits at the -2% wrt true black of 16...
[11:29] <ubitux> http://pastie.org/4119498  is it me or the ctts table here is completely broken?
[11:29] <ubitux> (it's from big buck bunny mov, 480p)
[11:29] <ubitux> looking at Qt specs, ctts is not defined anywhere
[11:30] <ubitux> and iso specs say it should not be negative
[11:30] <ubitux> (obviously the intented values here are signed, 0, 100 and -100)
[11:31] <ubitux> this actually reminds me of one issue...
[11:44] <ubitux> btw, nice mire: ffplay http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8
[11:53] <saste> ubitux: what do you suggest as the default size of showwaves?
[11:54] <saste> now i'm setting 800x200 but looks a bit "nonstandard"
[11:55] <saste> a w/h ratio >=2 should be fine
[11:55] <ubitux> there is still the "drop" effect?
[11:58] <ubitux> saste: https://en.wikipedia.org/wiki/File:Vector_Video_Standards2.svg i don't see one with a ratio >= 2
[11:58] <ubitux> :(
[12:00] <ubitux> got to go bbl
[12:17] <saste> well most oscilloscope seem to have a 10/8 aspect ratio, but then the screen is split vertically in two parts, each one having an aspect ratio of 10/4
[12:17] <saste> thus 600/240 seems a good choice

[13:43] <Sebastia> Hi, I am developer and want to offer and paid app with ffmpeg in the appstore! Now my question is: Am I facing legal problems when offering the ffmpeg binary in a paid/commercial app? I would give credit and link to source code in the about box! But may I get problems with mpegla or any other patent holder? Thank you in advance
[13:45] <Compn> you would have to buy each codecs license 
[13:45] <Compn> like mpegla license for mpeg2, h264
[13:46] <Compn> probably some kind of microsoft license for wmv
[13:46] <Sebastia> Hi compn, thanks for the fast answer!
[13:46] <Compn> a lot of companies just ship it without caring 
[13:47] <Compn> and most codec companies only charge for encoders
[13:47] <Sebastia> so if I want to offer it commercial in the Mac App Store I need to buy each license for beeing 100% sure not getting sued?
[13:47] <Compn> well i'm sure there are some other people already selling ffmpeg in the mac app store
[13:47] <Compn> and i'm sure they didnt buy licenses
[13:49] <Sebastia> I am sure too! but they might get accused by one of the copyright holders right?
[13:50] <Compn> its possible. i dont recall anyone selling ffmpeg that has gotten in trouble tho
[13:51] <Compn> also depends which country you are in
[13:51] <Compn> are you in a country which supports software patents ?
[13:52] <Sebastia> definitely
[13:52] <Sebastia> USA
[13:52] <Compn> oh ok
[13:53] <Compn> i think mpegla rules are something like 'you dont need a license / its free for the first 10,000 downloads'
[13:53] <Sebastia> yep that is right! but I hope to sell more apps than this amount even I am not sure!
[13:54] <iive> put your price so you can afford to buy the licence :)
[13:54] <Compn> sell 9000 of them, then use that money to buy a license :P
[13:54] <Compn> heh
[13:54] <Sebastia> and they won't find out directly! but the problem is if I offer a commercial product with patents I didn't paid for this might have legal issues as a result!
[13:54] <iive> with the units you sell.
[13:54] <Sebastia> :D good idea too :D
[16:02] <gnafu> ubitux: Yeah, that one.  It reminds me of the weirder anime movies I would see on the Sci-Fi channel on Saturday mornings when I was a kid and too young to understand what was going on.
[16:03] <ubitux> what anime? :)
[16:05] <gnafu> It was long enough ago that I don't recall.  It's just faint memories of hyper-violent, hard-to-follow, totally awesome anime :-D.
[16:05] <ubitux> approximative year?
[16:06] <ubitux> gnafu: please give some details, i'm interested
[16:07] <gnafu> Well, this stuff would have been on Sci-Fi maybe 16 years ago or something, and the movies themselves were probably from the '80s.
[16:07] <gnafu> I do remember one that was something like G.A.L. Force or similar, but I don't think that was one of the violent ones.
[16:07] <gnafu> And then some cyborg one (Cyborg 9?).
[16:08] <gnafu> It all blurs together :-).
[16:08] <gnafu> No, not Cyborg 9 it looks like.
[16:10] <ubitux> cyborg 9 reminds me of kaiba style :)
[16:10] <ubitux> gnafu: what was it about?
[16:11] <ubitux> characters etc? :)
[16:25] <gnafu> I'm sorry; I really don't remember much more.  I wish I did, because I just remember liking them :-D.  If I ever think of more or find something that looks familiar, I'll try to remember to let you know :-).
[16:28] <ubitux> ok :(

[16:55] <gnafu> It looks like they played Akira at some point, so that might have been one of them.  I have since watched it many times, so I'm not sure.  I will say it felt familiar the first time I watched it after its DVD release, so perhaps I saw it on Sci-Fi.
[16:55] <gnafu> I'm looking down this list to see what might spark a memory: http://en.wikipedia.org/wiki/List_of_programs_broadcast_by_Syfy#Anime_shown_on_Syfy
[16:57] <gnafu> I am pretty sure I watched Gall Force: Eternal Story, though I don't think that one was at all violent (I remember liking it just the same).
[16:58] <ubitux> ninja scroll is violent
[16:58] <ubitux> perfect blue as well
[16:58] <ubitux> requiem from the darkness too (à la jigoku shoujo)
[16:58] <gnafu> Yes, for sure.  I have since watched Ninja Scroll, but I don't think I caught it when it was on Sci-Fi.  I have yet to see Perfect Blue.
[16:59] <ubitux> if you like violent stuff i'd recommend Now & Then, Here and There
[16:59] <ubitux> dead leaves is nice and insane
[17:00] <ubitux> hey it's a pretty nice list actually/.
[17:00] <ubitux> if you omit appleseed
[17:00] <gnafu> Yeah, I think I should watch all of them eventually :-P.
[17:00] <gnafu> Aah, hehe.
[17:00] <ubitux> armitage is sci-fi
[17:01] <ubitux> similar to battle angel alita
[17:01] <ubitux> oh they passed Roujin-Z
[17:01] <ubitux> i saw that recently, insanely good :)
[17:02] <ubitux> from otomo, the guy of akira
[17:02] <gnafu> Cool.
[17:03] <gnafu> Wait, I have seen Perfect Blue.  It was a little while ago, and only once, but I remember it now.
[17:03] <gnafu> It was a good'un.
[17:05] <ubitux> Millenium Actress is IMO the best of Satoshi :)
[17:05] <ubitux> paprika & perfect blue were pretty nice too though :)
[17:05] <gnafu> Ooh, I do like that movie.  I have the DVD; it came in a two-pack with Ghost in the Shell 2.
[17:05] <ubitux> heh :)
[17:05] <gnafu> I haven't seen Paprika yet.
[17:06] <ubitux> you should see it at least for the music ;)
[17:07] <gnafu> Millenium Actress is decidedly more tame than the other two.
[17:08] <ubitux> it strangely makes me think of the movie (real movie, not anime) eternal sunshine of the spotless mind
[17:08] <ubitux> (and btw, paprika is related to the dreams & stuff)
[17:11] <gnafu> I seem to remeber an anime with a cyborg kid who asks for milk in a space bar.  Does that ring any bells?
[17:14] <ubitux> mmmh
[17:14] <ubitux> nope :(
[17:16] <iive> if you want violent, watch "When Cicadas cry", the first season is quite violent. the official translations uses "when they cry" as title..
[17:16] <gnafu> Oh, hehe.  I've heard of that one.
[17:17] <ubitux> it's an horror thing :p
[17:17] <ubitux> nails @_@
[17:18] <iive> Baccano! is also quite remarkable. "Narutaru" is probably the most torturous. it starts like pokemon and .... Well, too bad it is only half of the manga.
[17:19] <ubitux> i didn't like baccano
[17:19] <iive> basilisk is similar to ninja scroll.
[17:20] <ubitux> narutaru reminds me something...
[17:20] <ubitux> bokurano
[17:20] <ubitux> at least the cover :p
[17:20] <iive> "Black Magic M66" could be the cyborg one.
[17:21] <iive> ubitux: OOPS. I did mean bukurano, just got the wrong name. For some reason, I always confuse both.
[17:21] <ubitux> :)
[17:21] <iive> i mean the big mecha one. not the train mafia style immortals.
[17:22] <ubitux> yep :)
[17:23] <iive> darker than black. classic :)
[17:23] <ubitux> didn't like it :po
[17:24] <iive> it is bumpy, hard to watch, but there are moments that make it worth.
