[10:18] <saste> michaelni: when you have some time, could you have a look at the decimate issue?
[10:18] <saste> it's in my local repo since March, and I'd like to push it
[10:18] <saste> also tell if you're OK with removing mp=smartblur
[10:19] <michaelni> saste, "the decimate issue" ?
[10:20] <saste> michaelni: yes the bx8 block diff code in decimate seems wrong
[10:20] <saste> *8x8
[10:21] <saste> so I had to fix it in order to make it binary-exact with dsputil diff_pixels code
[10:22] <saste> and I can't test MMX mp=decimate implementation (is always disabled)
[10:24] <michaelni> hmm, yes, seems x is off by 1, y shouldnt matter
[10:25] <saste> indeed
[10:26] <michaelni> "CpuCaps gCpuCaps; //FIXME initialize this so optims work"
[10:26] <michaelni> shouldnt be too hard to initt gCpuCaps from our cpu detect code ...
[10:27] <saste> BTW is there some way to set cpu_caps at run time?
[10:27] <saste> for example if I want to test C implementation without to recompile everything
[10:27] <michaelni> ./ffmpeg -cpuflags ...
[10:27] <saste> ok, thanks

[19:15] <ubitux> michaelni: will look at it in a moment
[19:51] <saste> why bugzilla sucks so hard when you want to do a f*****g simple search?
[19:52] <ubitux> i never understood how it works
[19:53] <ubitux> it just looks like another bloated bug tracker from the 90s
[19:54] <Daemon404> still better than clearquest
[19:55] <llogan> i hate bugzilla
[19:57] <ubitux> Daemon404: the good thing with sucky things is that you can always find worse
[19:57] <Daemon404> did someone say bug mailing list?
[19:57] <Daemon404> i think someone said bug mailing list.
[19:58] <ubitux> :)
[19:58] <ubitux> mutt can certainly such better in e-mails than bugzilla in bugs ;)
[20:03] <ubitux> s/such/search/
[20:12] <iive> bugzilla is written in perl.
[20:21] <saste> iive: don't blame the language for the implementation
[20:21] <saste> anyway maybe it is intentionally so hard
[20:22] <saste> so that the only users who manages to create a report are skilled or masochistic enough to perform a good report
[20:22] <iive> you have to use the right tool for the right job.
[20:42] <philipl> ubitux: Do you still need to look at the diff more, or are you happy? (I've fixed the INT_MAX thing locally)
[20:49] <ubitux> philipl: what happens in case of a subtitles ` subrip and lace_duration>INT_MAX?
[20:49] <ubitux> it looks like none of the duration is set
[20:50] <ubitux> saste: is the cflags/ldlibs things fixing anything?
[20:50] <philipl> ubitux: Yes, but that's the same as before.
[20:50] <philipl> It deliberately doesn't set any duration for non-subrip subtitles.
[20:51] <philipl> For ass that's because it inserts inband timing.
[20:51] <philipl> For vobsub, I assume its because the inband timing was always there.
[20:51] <saste> ubitux: yes, although it is somehow a corner case
[20:51] <saste> suppose that you have libs in custom prefix, e.g. /opt/weird/ffmpeg
[20:52] <ubitux> philipl: should be ok then
[20:52] <philipl> Thanks.
[20:52] <saste> *e.g. /weird/path/
[20:53] <saste> then you want to install ffmpeg in /freak/ffmpeg/
[20:53] <saste> when you link, you update your PKG_CONFIG_PATH, so that ffmpeg libs are looked in /freak/ffmpeg, but the cflags/ldflags will point to /weird/path/
[20:53] <saste> with funny results
[20:54] <saste> a more practical example, I have libs installed in HOME, but I may want to install ffmpeg in /opt/ffmpeg, and test the examples against that install
[20:55] <saste> so I need to override the default cflags/ldflags
[20:55] <saste> note that I already patched the build for that much time ago
[20:55] <saste> (many build systems don't support that scenario, e.g. libx264)
[20:55] <ubitux> ok ok
[20:56] <ubitux> well should be ok then
[20:58] <saste> i'll push it soon then

[21:50] <CIA-56> ffmpeg: In case CFLAGS/LDLIBS are already defined and conflicting with the

[22:05] <ubitux> saste: please add demuxing to .gitignore :)
[22:06] <ubitux> saste: maybe we could use av_log() instead of the printf utils in the example?
[22:09] <ubitux> ah you just switched from av_log to fprintf heh.

[22:43] <brimestone> hey guys, i have a piece of footage that is shot in LogC. I'm wondering i can use FFmpeg to add a LUT/Color Profile to get the "normal" looking image in Rec709?
[22:46] <Compn> you want to switch the color profile ?
[22:46] <Compn> i thought there was a filter to do it in mplayer, which ffmpeg should have now
[22:46] <Compn> but i dont remember
[22:46] <brimestone> i think that is what i'm talking about 
[22:47] <Compn> you color profile guys sound like audiophiles :P
[22:47] <saste> matrixcolor?
[22:47] <brimestone> yes...
[22:47] <Compn> saste : http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2008-August/058341.html
[22:47] <Compn> saste : maybe it was never committed...
[22:48] <Compn> saste : but theres been at least 100 people asking for this feature, it would make a nice thing if ffmpeg doesnt have it...
[22:49] <brimestone> doesnt??
[22:52] <Compn> if you are encoding to x264 , x264 has a colormatrix option 
[22:52] <Compn> which can specify the thing
[22:53] <Compn> dnxhd encoder might as well
[22:54] <brimestone> hmmmm 
[22:55] <Compn> Convert HD YUV BT709 to SD BT601 and vice versa
[22:55] <Compn> FFmpeg customized for broadcast and professional usage. 
[22:55] <Compn> What you can do with FFmbc:
[22:55] <Compn> http://code.google.com/p/ffmbc/
[22:56] <Compn> that might be what you want brimestone
[22:56] Action: Compn afk
[22:56] <Compn> saste : merge ffmbc , gpl ifdef everything! :)
[22:57] Action: saste saste wonders why people ask him to do everything
[22:58] <Compn> mostly because everyone else avoids me
[22:58] <Compn> and michael is too busy ;)
[22:58] <ubitux> isn't vf colormatrix what you are looking for?
[22:58] <Daemon404> that was ported from avs
[22:58] <Daemon404> it isnt unique to ffmbc
[22:59] <Compn> maybe it just needs some advertising how to use it
[22:59] Action: Compn looks at saste to write docs
[22:59] <ubitux> there is some doc for the colormatrix filter
[23:00] <Compn> 28.8 colormatrix
[23:00] <Compn> The colormatrix filter allows conversion between any of the following color space: BT.709 (bt709), BT.601 (bt601), SMPTE-240M (smpte240m) and FCC (fcc). 
[23:00] <Compn> The syntax of the parameters is source:destination:  	colormatrix=bt601:smpte240m
[23:00] <Compn> so it is
[23:00] <Compn> brimestone : how come you dont read documentation then huh?
[23:00] <Compn> :P
[23:06] <brimestone> i do? 
[23:06] <brimestone> i just get confuse with the nomanclature of the Video world...
[23:14] <brimestone> that actually does convertion from bt709 to smpte? 
[23:17] <brimestone> what im trying to do is render a LogC footage from an Arri Alexa camera using a LUT file created by the Cinematographer on the field
[23:28] <nyuhu> saste : in your review of the process_command callback for hue youre suggesting to save the old hue values and then reset them ; in itself it is not necessary to save the old values since theyre not directly used in the processing (hue_[sin,cos] attributes are used instead but are computed from the hue). Should we still save them for the consistency ?
