[01:48:04] <CIA-7> ffmpeg: bcoudurier * r23100 /trunk/ (doc/libavfilter.texi ffmpeg.c): rename -vfilters cli option to -vf
[03:07:15] <peloverde> Anyone know any good audio waveform analyzers? audacity isn't giving me the granularity I need
[03:49:19] <peloverde> sorry, stupid wm keeps crashing
[05:18:38] <saintd3v> peloverde: baudline?
[05:19:10] <saintd3v> i think it has a waveform view
[05:19:38] <peloverde> i'll give it a look, thanks
[05:35:37] <ramiro> building ffmpeg for windows on msys took 5m49s. building ffmpeg for windows on ubuntu running under virtualbox on the same machine took 5m20s.
[05:36:29] <peloverde> msys is slow
[05:36:47] <Dark_Shikari> s/msys/windows
[05:36:53] <Dark_Shikari> the problem is fork is slow
[05:40:33] <ramiro> I switched the configuration on my quad core. it used to be ubuntu running a few windows vboxes. now it's windows (2008r2) running one ubuntu vbox (for irssi, of course, the most important reason I keep this box =).
[05:40:53] <Dark_Shikari> also, really, building ffmpeg only took 5 minutes on windows?
[05:40:57] <Dark_Shikari> what version of windows?
[05:41:05] <Dark_Shikari> it takes about that long to run _configure_ here
[05:41:42] <ramiro> windows 2008 server r2 on a q6600 (make was not parallelized)
[05:42:22] <ramiro> the fate tests will be down until I finish setting up the new toolchains.
[05:47:51] * peloverde 1 - 0 spatial holes
[05:48:09] <Dark_Shikari> does it still sound worse than faac at half the bitrate?
[05:49:33] <peloverde> depends on the number of channels and if it is in constant quality mode or constant bitrate mode
[05:49:42] <drv> configure takes ~1m to run on my c2d win7 x64 system with msys, and about half of that is the "Creating config.mak and config.h..." step
[05:55:12] <Dark_Shikari> 3 minutes 52 seconds here
[05:55:16] <Dark_Shikari> win7, cygwin 1.7
[05:55:30] <drv> cygwin redefines slow
[05:55:40] <drv> (not that msys is a speed demon either)
[05:56:45] <Dark_Shikari> cygwin was much faster on xp
[05:56:51] <Dark_Shikari> something in the kernel must have made fork slower.
[05:59:48] <peloverde> oh shit, psymodel bugs, or at least bugs in my understanding of the psymodel
[06:02:35] <peloverde> it seems like masking theresholds are way too high in the remaining windows after an attack
[06:02:51] <peloverde> sigh, I should really just be writing this down
[06:09:55] <peloverde> I guess I hope that if I ramble about it enough someone will take interest and join in
[06:36:28] * _av500_ joins in rambling
[06:49:45] <KotH> salut mes amis
[07:04:55] <Tjoppen> dags för morgonkaffe
[07:08:17] * _av500_ wakes slowly
[07:15:20] <KotH> Tjoppen: coffee is something you drink in the afternoon, not in the morning
[07:15:33] <KotH> .o0(alles barbaren hier)
[07:23:41] <merbzt1> http://www.google.com/patents?id=XYYHAAAAEBAJ&printsec=abstract&zoom=4&source=gbs_overview_r&cad=0#v=onepage&q&f=false
[07:32:04] <Tjoppen> KotH: pff, the day starts with coffee, and continues with coffee. it also ends with coffee
[07:33:16] <Tjoppen> merbzt1: wtf? also, lots of prior art
[09:19:35] <Kovensky> merbzt1: I remember seeing that linked on cracked.com
[11:07:30] <pentanol>  peloverde about audio waveform analyzer, probably you're looking for oscilloscope?
[13:26:42] <Tjoppen> is there a way to ensure AVPacket::dts gets set?
[13:28:18] <Tjoppen> I'm getting audio packets without DTS from the MXF demuxer, which I find a bit odd
[13:30:40] <j-b> good morning
[13:33:29] <mru> morning j-b
[13:34:53] <av500> j-b: gm
[13:38:26] <j-b> Is '[mxf @ 0x831d880]MAX_READ_SIZE:5000000 reached
[13:38:46] <j-b> Is '[mxf @ 0x831d880]MAX_READ_SIZE:5000000 reached' an issue, a warning, an error, or none of the above?
[13:39:13] <Compn> good question
[13:42:34] <mru> none of the above: it's a nuisance
[13:44:38] <j-b> It is a bit annoying, yes
[13:45:33] <j-b> I'll wait for master Coudurier to come, and 'll ask
[13:52:33] <pentanol> hello, may be some one knows why after receiving rtsp stream I've got Duration: N/A, start: 0.000000, bitrate: N/A   and also itn's palying
[13:53:46] <Kovensky> j-b: he same happens with the mpegps demuxer
[13:53:48] <Kovensky> the*
[13:54:04] <Kovensky> Tjoppen: on audio, isn~t dts == pts:
[13:54:09] <Kovensky> oh stupid br-abnt2 keyboard
[13:54:33] <Tjoppen> yes. the odd part is that if demuxes everything fine, except for the last packet in each audio stream
[13:54:58] <Tjoppen> I have MXF with one DVCPRO100 stream and four pcm_s24le streams
[13:55:49] * Kovensky wonders why do the pcm_* decoders have framesize == samplesize
[13:55:58] <Tjoppen> I'm actually patching the demuxer since it produces bogus values for pkt->ofs
[13:56:32] <kierank> [14:54] <Kovensky> Tjoppen: on audio, isn~t dts == pts: --> huh
[13:56:55] <kierank> which audio does dts != pts
[13:57:10] <kierank> oh you are asking the question
[13:57:16] <Kovensky> nah, he just said that DTS isn't being set
[13:57:20] <Kovensky> what if PTS is? :>
[13:57:38] <Kovensky> (which is weirder, ofc)
[13:59:22] <Tjoppen> on, PTS isn't set either
[13:59:30] <Tjoppen> I check for that first, and use DTS if no PTS is set
[14:00:03] <Tjoppen> documentation of AVPacket says DTS can be AV_NOPTS_VALUE. I wonder for what reason though
[14:00:34] <Kovensky> DTS is AV_NOPTS_VALUE on streams with B-frames, according to the edocs
[14:02:55] <Tjoppen> but then PTS should be set. also, this is audio :o
[14:03:24] <Tjoppen> maybe the mxf demuxer failing regtests has something to do with this
[14:15:12] <Tjoppen> heh, backing up a bit makes the tests pass
[14:15:26] <Tjoppen> however, my patch makes them fail because it makes the mxf demuxer output correct values for pkt->ofs :)
[14:47:54] <Tjoppen> there we go. patch sumitted to list
[14:55:42] <Tjoppen> getting bogus PTS and DTS makes no sense though
[17:06:45] <CIA-7> ffmpeg: reimar * r23101 /trunk/libavcodec/utils.c:
[17:06:45] <CIA-7> ffmpeg: Set coded_frame to NULL when closing a codec, since it might
[17:06:45] <CIA-7> ffmpeg: be invalid after the codec is "gone".
[18:16:09] <BastyCDGS> yippie, exams for today finished :)
[18:16:12] <BastyCDGS> back @ home
[18:54:06] <Tjoppen> BastyCDGS: party time in other words
[18:54:19] <BastyCDGS> yes until sunday ;)
[18:54:36] <thresh> partying is cool.
[18:54:41] <BastyCDGS> monday next exam writing from 6-14 UTC
[18:55:03] <BastyCDGS> got some beer for tonight ;)
[18:55:40] <thresh> but, in Soviet Russia, the Party always find you.
[18:55:49] <thresh> not the other way round :(
[18:56:17] <BastyCDGS> oh here in liege are often spontaneous events
[18:59:30] <BastyCDGS> had just one two weeks ago
[19:00:39] <BastyCDGS> just got invited to disc throwing in the park and then they took me to a nice afternight party with excellent food and some funny people :)
[19:01:15] * thresh usually have parties going on from Friday night till... well
[19:01:37] <BastyCDGS> that's great!
[19:01:47] <thresh> till you know when. I rarely last for more than Sat midnight though
[19:02:18] <BastyCDGS> Sounds like me when going to goa festivals or goa parties in berlin ;)
[19:03:21] <BastyCDGS> that's when I'm longer partying
[19:03:23] <thresh> those are usually 'hey, let's go to that pub; and then to the other one; and then to a club; and then to someone's flat; ..." etc etc :-)
[19:03:39] <thresh> not a big fan of trance music myself
[19:03:59] <_av500_> thresh: always end with an irish pub, u know...
[19:04:18] <BastyCDGS> what do you listen too?
[19:04:51] * BastyCDGS is just listening to cafe del mar
[19:05:18] <thresh> _av500_: yes. This is a good rule when brain decides what to do. Cant stand to go somewhere else when filled with irish spirit, though.
[19:05:54] <thresh> BastyCDGS: something like stuff here: http://www.last.fm/user/thresh
[19:11:53] <BastyCDGS> interesting to listen to, but I'm not in mood for that kind of music right now. I just want to calm down.
[19:17:59] <Dark_Shikari> ffmpeg 0.5.1 is supposed to still have vhook, right?
[19:18:44] <peloverde> I think
[19:34:39] * peloverde sees that psy bands are computed after several processes that use them
[19:34:45] * peloverde headdesk
[19:46:59] <BastyCDGS> well guys I will have some sleep now, totally tired. Wish you all good night.
[20:12:45] <janneg> does someone know if hddvd/evo uses non mpeg1/mpeg2 extensions pes packet headers?
[20:21:00] <Dark_Shikari> revision 31153 in swscale broke things
[20:21:10] <Dark_Shikari>  http://pastie.org/957655
[20:21:22] <Dark_Shikari> ramiro: ping
[20:33:41] <ramiro> Dark_Shikari: pong
[20:35:13] <ramiro> I did you bisect to 31153?
[20:35:47] <Dark_Shikari> ramiro: yes
[20:35:50] <Dark_Shikari> well, I didn't, use in #ffmpeg did
[20:36:41] <ramiro> I don't have time to look now, I'll just revert for the moment
[20:38:23] <janneg> nevermind, it's just fake startcodes in private_stream_1's data
[22:18:23] <CIA-7> ffmpeg: stefano * r23102 /trunk/libavformat/avformat.h: Doxygen av_codec_get_id() and av_codec_get_tag().
[22:38:54] <CIA-7> ffmpeg: lorenm * r23103 /trunk/libavcodec/bitstream.c: change a variable-length array to a malloc.
[23:19:05] <CIA-7> ffmpeg: bcoudurier * r23104 /trunk/ffplay.c: rename -vfilters cli option to -vf in ffplay as well
[23:44:10] <janneg> any patch monkeys around?
