[06:51:49] <lu_zero> yawn+moin
[06:57:29] <Tjoppen> morrn
[07:11:16] <andoma> morning
[07:12:59] <kshishkov> god morgon
[07:18:06] <_av500_> gm
[07:18:25] <cartman> good moroning
[07:21:59] <superdump> morning
[07:22:37] * kshishkov remembers good old #ffmepg-devel where all channel activity was saying either "good morning" or "hi"
[07:22:54] <saintdev> hi
[07:23:46] <thresh> good morning
[07:24:45] <elenril> http://tvtropes.org/pmwiki/pmwiki.php/Main/Hello
[07:25:10] <kshishkov> thresh: your stolen greeting is in Turkey
[07:25:43] <thresh> kshishkov: it mutated a lot
[07:37:51] <pJok> god morgon kshishkov
[07:38:04] <kshishkov> god morgon, pJok
[07:39:10] * pJok does not understand how swedish people can eat that Kalles Kaviar thing in the morning...
[07:39:16] <pJok> its nothing but salt
[07:39:53] <kshishkov> and some nutrients
[07:40:40] <pJok> well, the one i got this morning was at least 50% smoked salmon
[07:40:55] <pJok> what the rest was, apart from salt, i didn't bother checking
[07:41:14] * kshishkov would also care only for salmon
[07:45:57] <pJok> kshishkov, http://humon.deviantart.com/gallery/#/d2gdg8t
[07:49:45] <saintdev> lol
[07:50:12] <pJok> should pretty much illustrate what sweden does to their fish
[07:54:32] <superdump> i guess iceland still wins
[07:56:11] <Tjoppen> :)
[07:56:31] <pJok> superdump, except in iceland, thats just a rare delicacy... rotten fish in sweden isn't rare ;)
[07:56:46] <Tjoppen> also, kalles + eggs = win
[07:57:12] <Tjoppen> the salt content means you don't need to add any salt to the egg
[07:58:00] <pJok> hmm
[07:58:06] <pJok> you've got a point there
[07:58:11] <pJok> probably worth a try
[08:00:02] <superdump> well, thank goodness i'm vegetarian ;p
[08:00:14] <Dark_Shikari> Vegeterian?  Lame!
[08:00:16] <Dark_Shikari> You miss out on bacon.
[08:01:35] <pJok> superdump, some vegetarians do eat fish :P
[08:01:42] <superdump> i don't
[08:01:44] <pJok> at least my vegetarian colleague does
[08:01:53] <saintdev> then they're not a vegetarian
[08:02:04] <superdump> they're still a type of vegetarian
[08:02:04] <pJok> you are thinking vegan
[08:02:19] <superdump> there are different types of vegetarian
[08:02:19] <Dark_Shikari> vegans don't eat animal-derived products that aren't meat either
[08:02:22] <Dark_Shikari> e.g. butter, milk
[08:02:36] * superdump is a lacto-ovo vegetarian
[08:02:38] <Dark_Shikari> vegetarians eat cheese
[08:02:45] <superdump> i.e. i eat dairy produce
[08:02:47] <saintdev> if you eat meat you're not a vegetarian
[08:02:50] <saintdev> fish = meat
[08:03:10] <superdump> for whatever reason, many people consider fish a different class
[08:03:15] <superdump> i don't really know why
[08:03:22] * pJok doesn't care
[08:03:29] <Dark_Shikari> I don't think they're any different
[08:03:30] <Dark_Shikari> they're just as tasty
[08:03:34] <superdump> but there is a class of vegetarian called pesco vegetarianism as i recall
[08:03:58] <superdump> but i don't really consider it vegetarianism myself
[08:04:04] <saintdev> they're just the wannabes of the vegetarian world
[08:04:50] * pJok stops himself from trolling
[08:04:53] <Dark_Shikari> Or the people who realize that fish is really tasty.
[08:05:05] <kshishkov> pJok: in Norway they have lutefisk. Yummy!
[08:05:10] <Dark_Shikari> I'm a tastyarian.  I eat things that are tasty.
[08:05:35] <saintdev> i like that classification :D
[08:05:42] <pJok> kshishkov, i know... its not rotten fish, its just.... very preserved fish...
[08:05:48] <Dark_Shikari> Gefilte fish?
[08:06:31] <kshishkov> pJok: also your or mine stomach probably won't tolerate rotten whale or fish while Icelandic or Inuit guys will eat it without problems - the same story with Asians who can't drink milk
[08:06:35] <pJok> Dark_Shikari, lutefisk is fish preserved in lye
[08:06:57] <pJok> kshishkov, im quite sure my nose wont tolerate the smell either...
[08:07:15] <Dark_Shikari> also, superdump, jewish tradition considers food to fall into three categories
[08:07:18] <Dark_Shikari> meat, dairy, and parve
[08:07:20] <Dark_Shikari> Fish are parve
[08:07:23] <Dark_Shikari> which may relate to that.,
[08:07:57] <kshishkov> Dark_Shikari: I thought it was halal, kosher and treif
[08:08:33] <kshishkov> i.e. what you can eat on Pesakh, on every day and when rabbi don't see you
[08:08:54] <Dark_Shikari> lol
[08:08:58] <pJok> pigs are everywhere
[08:09:43] * pJok hands Dark_Shikari a can of tactical bacon
[08:09:47] <saintdev> and bacon is delicious
[08:09:50] <Dark_Shikari> +1
[08:10:52] <kshishkov> in Ukraine even prok is kosher
[08:10:54] <kshishkov> *pork
[08:11:08] <kshishkov> (but only in Ukraine)
[08:11:40] <thresh> what about lard in chocolate?
[08:12:15] <kshishkov> that's produced too
[08:14:03] <pJok> mmmmh, bacon chocolate
[08:16:40] <kshishkov> the best food for Muslims as well
[08:18:56] * cartman ate pork only once and hate it
[08:20:03] <kshishkov> ever tried poultry? There is one kind of bird appropriately named in English...
[08:24:21] <superdump> ?
[08:25:49] <superdump> pigeon?
[08:27:52] <kshishkov> Turkey
[08:28:13] <spaam> :D
[08:28:28] * kshishkov considers pigeons to be either flying rats or flying cockroaches
[08:32:28] <pJok> kshishkov, there's a flying rat outside my workwindow... and its busy feeding its flying rat offspring
[08:33:00] <Dark_Shikari> kshishkov: http://i34.tinypic.com/10mmwax.gif
[08:35:47] <superdump> kshishkov: i think 'bat' in swedish is something like 'flapping mouse'
[08:36:08] <superdump> fladdermus or something like that
[08:36:21] <pJok> yeah
[08:36:25] <kshishkov> similar in German
[08:36:48] <Tjoppen> batman is called "the leather patch" in swedish
[08:37:07] <superdump> really?
[08:40:09] <kshishkov> yes, the first phrase in Swedish Wikipedia for it
[12:18:05] <lu_zero> aballier: strange rgb2rgb_template.c:36:5: warning: "HAVE_SSE2" is not defined
[12:19:54] <lu_zero> the configure checks is for HAVE_SSE
[12:20:13] <lu_zero> so I guess that code really doesn't do anything
[14:22:09] <CIA-93> ffmpeg: mstorsjo * r24797 /trunk/libavformat/ (sdp.c rtpenc_vp8.c rtpenc.c Makefile rtpenc.h):
[14:22:09] <CIA-93> ffmpeg: Add RTP packetization of VP8

[14:24:35] <CIA-93> ffmpeg: Add RTP depacketization of VP8
[14:24:35] <CIA-93> ffmpeg: Patch by Josh Allmann, joshua dot allmann at gmail
[15:34:00] <twnqx> http://www.techeye.net/software/dukenukemforever-is-back-from-the-dead yey!
[15:35:56] <Tjoppen> well, tf2 came out. who knows, maybe dnf too?
[15:49:27] <Kovensky> maybe mplayerg2 will return too?
[15:50:04] <Kovensky> also twnqx, you weren't paying attention to #shameimaru enough; I linked the news from kotaku 3 days ago :P
[15:50:23] <twnqx> :O
[15:51:00] * Kovensky wonders if golgol7777's freqeuent disconnections are due to doubleroute changing routes
[16:00:07] <lu_zero> Kovensky: ?
[16:00:47] <Kovensky> lu_zero: ?
[16:01:04] <KotH> .o0(?)
[16:03:48] <lu_zero> what's #shameimaru?
[16:04:14] <mru> join and find out
[16:04:22] * mru wouldn't
[16:04:40] <mru> it may well be worse than #netbsd-furries
[16:05:31] <Kovensky> lol
[16:05:40] <Kovensky> it's on rizon
[16:06:22] <KotH> and netbsd-furries is/was on freenode... so shameimaru is definitly worse
[16:06:31] <KotH> wait a sec.. you're on rizon?
[16:06:45] <Kovensky> yes ._.
[16:06:57] <KotH> who are you and what did you do with Kovensky?
[16:07:06] <Kovensky> lol
[16:07:11] <Kovensky> you never knew? =p
[16:07:19] <KotH> nope ^^'
[16:08:11] <Kovensky> anyway, #shameimaru was supposed to be a fansub group but we've had one release in 1.5yrs so it's p. much a place where people talk about animu / touhou / games / lunix / dev / multimedia stuff / whatever
[16:09:06] <lu_zero> ah
[16:09:26] <lu_zero> higurashi and umineko are a topic there as well?
[16:09:30] <Kovensky> yes
[16:09:37] <lu_zero> fun
[16:10:00] <KotH> sounds like the average anime channel
[16:12:00] <Kovensky> maybe
[16:12:23] <KotH> maybe? just have a look at #mplayer and #ffmpeg... they are much the same!
[16:13:01] <Kovensky> it lacks the perl and the pixiv spam ;)
[16:13:32] <Kovensky> probably lacks the encoding too, because >mencoder ._.
[16:15:18] * KotH wonders whether he should debug this damn usb code or read something about phase noise and jitter in high stable oscillators
[16:15:34] <Kovensky> lol
[16:15:38] <elenril> KotH: watch some anime
[16:15:50] * Kovensky is watching rurouni kensin atm
[16:15:52] <elenril> or read some mystery novels
[16:16:09] * elenril isn't watching anything because new fma sucks
[16:16:13] <Kovensky> catastrophic dub is catastrophic
[16:16:16] <KotH> elenril: no anime available at work
[16:16:27] <elenril> Kovensky: loldub?
[16:16:36] <elenril> KotH: youtube?
[16:16:47] <KotH> elenril: er... i didnt sink that low yet
[16:17:45] <elenril> watch a crappy anime?
[16:19:13] <lu_zero> KotH: what's wrong with usb?
[16:19:37] <lu_zero> want to exchange for an exa implementation with some ops tinting in red everything?
[16:23:20] <KotH> lu_zero: enumeration works, communication does not... and it doesnt help that running the app that is supposed to communicate with the device, crashes my usb data tracer
[16:23:34] <lu_zero> ouch
[16:23:53] <KotH> which is supposed to be impossible
[16:24:06] <KotH> (single, stand alone device)
[16:24:07] <lu_zero> there is an off by one
[16:24:22] * lu_zero randomly answer
[16:24:23] <KotH> probably a dozen of those, combined with some race conditions
[16:24:50] <lu_zero> uhmm
[16:24:52] <KotH> who ever designed usb didnt think about the poor people who have to implement it
[16:25:36] <lu_zero> ^^;
[16:27:24] <KotH> or did you know that the specs for the serial devices is more than 10 times the size than the usb core specification (including everything from mechanical dimensions up to the base parts of the logical protocol)
[16:37:59] <lu_zero> uhmm
[19:48:39] <peloverde> ಠ_ಠ make fate-imdct
[19:48:50] <Dark_Shikari> BBB: so
[19:48:53] <Dark_Shikari> weekend results? =p
[19:49:23] <mru> peloverde: ?
[19:49:57] <peloverde> It complains about SAMPLES even though it doesn't seem to use SAMPLES
[19:51:30] <mru> peloverde: hmm, that's probably true
[19:51:47] <mru> you could always set it to something arbitrary then :-)
[19:54:21] <peloverde> Yes, I've been doing "make fate-imdct SAMPLES=."
[19:54:51] <mru> you can also run fft-test manually
[20:07:45] <peloverde> (I've been looking at imdct on win64 for reasons I don't even understand)
[20:23:22] <merbanan> peloverde: same error as with suncc ?
[20:23:49] <peloverde> merbanan: no, the problem is with xmm clobbers
[20:23:49] <mru> fate says no
[20:23:59] <mru> isn't fft yasm?
[20:23:59] <peloverde> which then turns into a problem of split asm sections
[20:24:08] <peloverde> fft is, the imdct wrapper is not
[20:24:14] <merbanan> computer says no
[20:24:15] <mru> yuck
[20:24:17] <mru> why not?
[20:24:50] <Dark_Shikari> because michael
[20:24:59] <peloverde> In some places it seems to decide defers to gcc's judgement for whatever reason
[20:25:43] <peloverde> in its current form it is blocking win64 so it needs to change
[20:25:45] <mru> Dark_Shikari: pengvado did the fft
[20:25:59] <Dark_Shikari> but that's the imdct wrapper
[20:27:23] <mru> pengvado did those too
[20:27:29] <Dark_Shikari> hmm, probably should ask him then
[20:27:53] <mru> and they're 98% asm anyway
[20:28:36] <mru> doing the neon version in pure asm was easy
[20:29:07] <mru> I guess he used C to avoid accessing structs from asm
[20:29:33] <Dark_Shikari> yeah
[20:29:37] <Dark_Shikari> accessing structs from asm is dangerous imo
[20:29:41] <Dark_Shikari> and annoying
[20:29:49] <mru> this is a struct with ~4 members
[20:29:49] <Dark_Shikari> maintenance nightmare
[20:29:52] <mru> not a problem
[20:30:03] <Dark_Shikari> oh, true
[20:30:05] <mru> accessing MpegEncContext from asm is hell
[20:30:06] <Dark_Shikari> it's not like in x264
[20:30:08] <Dark_Shikari> h->loopf.deblock_strength( h->mb.cache.non_zero_count, h->mb.cache.ref, h->mb.cache.mv,
[20:30:12] <Dark_Shikari> Or mpegenccontext.
[20:30:15] <Dark_Shikari> similarly messy.
[20:35:01] <CIA-93> ffmpeg: mru * r24799 /trunk/libavcodec/fft-test.c: fft-test: format error output more readably
[20:35:32] <peloverde> I'm not sure I can fix this nicely without moving it to yasm
[20:36:00] <mru> just do it
[20:47:16] <saintdev> peloverde: ping
[20:47:22] <peloverde> pong
[20:47:53] <saintdev> aacx seems to display the same scalefactors for all the short blocks in a frame
[20:49:39] <peloverde> Yeah, you said that, I was traveling all of last week
[20:49:53] <saintdev> ok, wasn't sure if you saw it ;)
[21:16:18] <BBB> hey guys
[21:16:23] <BBB> I've got a firmware file here
[21:16:31] <BBB> and an exe that sends it to a device
[21:16:39] <BBB> I'd like to decrypt the firmware
[21:16:45] <BBB> does anyone have experience with that?
[21:17:40] <BBB> (the exe supposedly has code for decrypting also, and I don't have any reason to believe the encryption is anything more but a minor compression or image-bundling or something along those lines)
[21:17:41] <roxfan> got a link?
[21:17:59] <BBB> to exe or to fw?
[21:18:05] <roxfan> both
[21:18:05] <BBB> http://support.pelco.com/browse.php?fFolderId=565
[21:18:21] <roxfan> ok
[21:25:51] <Compn> BBB : i assume you ran strings on exe and firmware to look for things like 'pkjextract' or 'bzip' ? :P
[21:26:06] <BBB> file tells me nothing about the img file
[21:26:15] <BBB> I didn't do anything obvious on the exe yet, trying to get wine working
[21:28:38] <BBB> there's a gzip string in the exe
[21:28:41] <BBB> that's about all I can see
[21:28:47] <BBB> unfortunately, gunzip can't handle the file
[21:29:06] <BBB> no extract or pk strings
[21:29:25] <mru> try 7zip
[21:29:32] <mru> it supports quite a few formats
[21:30:13] <lu_zero> BBB: managed to unpack it?
[21:30:41] <BBB> holy shit
[21:30:45] <BBB> 7zip handled it
[21:30:53] <Dark_Shikari> 7zip is pretty awesome
[21:30:58] <J_Darnley> What compression does it say?
[21:31:00] <Dark_Shikari> it's like the mplayer of compression formats
[21:32:54] <lu_zero> p7zip ?
[21:32:58] <lu_zero> or the window stuff?
[21:33:42] <BBB> not sure
[21:33:52] <BBB> but the firmware isn't what I'm looking for
[21:33:56] <BBB> but at least I have a mechanism now
[21:34:08] <BBB> I'm being told this company uses ffmpeg
[21:34:11] <BBB> I'm trying to see if they do
[21:52:46] <BBB> dammit
[21:52:58] <BBB> is there an easy way to break a zip file password?
[21:53:04] <BBB> (same purpose, in case you're asking)
[21:57:39] <lu_zero> fcrackzip
[21:57:49] <lu_zero> app-crypt/fcrackzip a zip password cracker
[21:58:32] <roxfan> BBB: gzip data at 0D000
[22:23:56] <roxfan> looks like it's a TI DSP
[22:26:11] <Dark_Shikari> so, nobody ever approved my fucking mail to the ML
[22:26:13] <Dark_Shikari> it's been like a week
[22:28:10] <J_Darnley> Send another with a link instead of attachment
[22:29:02] <BBB> or kick mru
[22:30:18] <lu_zero> Dark_Shikari: which email?
[22:32:45] <mru> ow
[22:35:04] <Dark_Shikari> J_Darnley: my patch to make ffh264 50% faster
[22:35:33] <J_Darnley> In a special case (readint the mail now)
[22:35:45] <Dark_Shikari> Yes yes yes
[22:35:58] <BBB> some of these approaches are more widely useful
[22:36:01] <BBB> I think it's cool :)
[22:36:02] <Dark_Shikari> "if you control the encoder and don't care about compression"
[22:37:59] * Dark_Shikari kicks mru
[22:38:06] <mru> why?
[22:38:10] <Dark_Shikari> approve my message
[22:38:14] <Dark_Shikari> don't you have ml admin or something
[22:38:18] <mru> I did already
[22:38:22] <Dark_Shikari> oh you did
[22:38:29] <Dark_Shikari> ah there it is
[22:38:29] <Dark_Shikari> thanks.
[22:42:28] <BBB> well I could actually help in speeding up h264dec :-p
[22:42:36] <Dark_Shikari> you have xvp8 to write1
[22:42:37] <BBB> that's a pretty easy one also
[22:42:46] <BBB> I'm working on that too
[22:42:57] <BBB> and everyone wants me to work on their special license violation \o/
[22:43:01] <BBB> /o\
[22:43:05] <Dark_Shikari> special license violation?
[22:43:16] <BBB> I have like a hundred in my inbox right now
[22:43:20] <Dark_Shikari> lol
[22:43:25] <BBB> all ffmpeg :-p
