DocScrutinizer05 | Oksana: afaik omap3430-dsp-libraries-ti only supports H.263/264_low-profile - see http://www.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?contentId=14649&navigationId=12643&templateId=6123 >>IVA™ 2+ (Image Video Audio) accelerator enables multi-standard (MPEG4, WMV9, RealVideo, H263, H264) encode/decode at D1 (720x480 pixels) 30 fps, and up to 720p resolutions<< | 00:06 |

DocScrutinizer05 | btw H.26(3/4) are encumbered by software patents according to wikipedia. Which gives a hint why Nokia would not have included any codecs for it that are not shipped by TI already | 00:19 |
Oksana | Hmm... I heard about 1080p playback support somewhere? But anyway, display is only 800x480, so I should try a different resolution, I guess | 00:21 |
Sicelo009N | we never had 1080p | 00:24 |
*** _rd has quit IRC | 00:27 | |
jon_y | obviously we need to push it by supporting h265 playback :) | 00:28 |
jon_y | seriously though h265 compression is pretty insane | 00:28 |
jon_y | while somehow still maintaining crisp quality | 00:28 |

salamisami | KotCzarny: How exactly does the volume control work in oscp | 11:39 |
salamisami | changing the volume seems to have no effect | 11:40 |
KotCzarny | salamisami: it uses softvol, it doesnt touch system volume | 11:40 |
KotCzarny | might be bugged because lately i've added libav resampler which might skip softvol in oscp | 11:40 |
KotCzarny | thx for reminding me | 11:41 |
KotCzarny | until i upload the fix you can just click status bar near the clock and change system volume | 11:42 |
salamisami | not that straightforward with ssh :P | 11:46 |
KotCzarny | ahm | 11:46 |
KotCzarny | still, its a bug, and i've added it to the TODO | 11:46 |

*** troulouliou_div2 has joined #maemo | 11:49 | |
*** xorly has joined #maemo | 12:01 | |
Sicelo009N | softvol means? how does one adjust it? | 12:03 |
KotCzarny | sicelo, softvol means every sample is multiplied by some float by oscp, and that float is changeable by user (via -/= keys or clicking on vol bar) | 12:03 |

KotCzarny | can you upload any of them somewhere? | 13:40 |
salamisami | i got them by using mp3fiber to download them from youtube since i couldnt find them elsewhere | 13:40 |
KotCzarny | offtopic, use youtube audio/video downloader for firefox | 13:41 |
KotCzarny | it allows to download audio tracks of youtube clips easily and with selectable qulity | 13:41 |
KotCzarny | *quality | 13:41 |
Sicelo009N | or cutecube2 on your N900 | 13:42 |
KotCzarny | and note that oscp can play webm/mp4/m4a/ogg/opus etc | 13:43 |

DocScrutinizer05 | I every once in a while notice WLAN locking up when walking out of range of an associated AP | 18:23 |
DocScrutinizer05 | it seems to desperately try to reconnect to the no longer available AP and never check for new ones, neither switch to other connectivity channels i.e. GPRS | 18:25 |
bencoh | I guess disabling/enabling wireless from the status-menu would work as well | 18:25 |
DocScrutinizer05 | yes | 18:25 |
Sicelo | if you have the applet :) stock does not have enable/disable wireless on status menu | 18:26 |
KotCzarny | hmm | 18:27 |
KotCzarny | it has 'select new connection' | 18:27 |

DocScrutinizer05 | re xprot I suspect it's quite a bit overengineered. I honestly doubt you need to ask BME(!!) about any temperature to determine whatever XPROT does to protect the speakers | 20:26 |
DocScrutinizer05 | or would the IHF audio shut down when battery gets too hot? to protect battery from discharge-induced overheating? | 20:28 |
KotCzarny | more like glue on speakers getting hot | 20:28 |
KotCzarny | (and thats why it has to limit displacement more) | 20:28 |
*** eMHa has quit IRC | 20:30 | |

*** darkschneider has joined #maemo | 21:27 | |
freemangordon | DocScrutinizer05: or most-probably they have had the same/similar problem with some other device and just reused the code | 21:27 |
bencoh | freemangordon: did you see anything ""relevant"" in xprot? | 21:29 |
freemangordon | "relevant" as in? | 21:30 |
bencoh | any function that seems to do something "useful" | 21:31 |
bencoh | and/or that we understand | 21:31 |
freemangordon | well, the thing xprot does is a HPF | 21:31 |
KotCzarny | fmg, isnt its more than that? | 21:32 |
Wizzup | freemangordon: right, so not ofono. well regardless, currently I don't get working gprs (problems in kernel modules) | 21:32 |
KotCzarny | ie. limiting cone displacement is not only hpf | 21:32 |
bencoh | freemangordon: highpass filter? | 21:34 |
freemangordon | KotCzarny: well, I didn't done thorough analysis of what xprot does, but check pngs in http://46.249.74.23/xprot/ | 21:34 |
bencoh | haha, my browser marks the two jpeg links as "already visited" :-) | 21:35 |
freemangordon | bencoh: yes, highpass filter | 21:35 |
KotCzarny | ~xprot | 21:35 |
infobot | xprot is, like, http://wiki.maemo.org/Porting/Audio/Q_and_A_RE-PA and http://talk.maemo.org/showthread.php?t=91325 | 21:35 |
freemangordon | KotCzarny: http://46.249.74.23/xprot/xprot.png is the input, http://46.249.74.23/xprot/xprotraw.png - the output | 21:36 |
bencoh | hmm, I guess the speaker response curve is the opposite/inverse, or I dont see how we're supposed to listen to music with that | 21:36 |
bencoh | (unless speakers were never meant to listen to music) | 21:36 |
freemangordon | KotCzarny: or you can take the 2 raw files and do whatever analysis you want :) | 21:36 |
freemangordon | bencoh: wait, why? | 21:37 |
KotCzarny | What is xprot displacement? | 21:37 |
KotCzarny | XProt displacement - don't remember. Something about the speaker coil safe traversal probably. | 21:38 |
KotCzarny | for some reason they mantion it and not a simple hpf | 21:38 |
bencoh | wait, xprot.png is input? | 21:38 |
KotCzarny | *mention | 21:38 |
freemangordon | sure, this is not a simple hpf | 21:38 |
freemangordon | but functions similarly to | 21:38 |
KotCzarny | would be meaningful to draw sines/triangles before/after xprot? | 21:39 |
KotCzarny | maybe square waveforms too | 21:39 |
freemangordon | sines doesn't make sense | 21:39 |
freemangordon | squares might make sense, but still, I expect output similar to that of an HFP | 21:40 |
freemangordon | also, there is a controlled gain, I guess based on the predicted coil temp | 21:40 |
bencoh | isn't it more of a bandpass if the two pictures are input/output? | 21:41 |
bencoh | centered around ... 1k-2k? | 21:41 |
freemangordon | yeah, why not :) | 21:41 |
freemangordon | but see the input dB | 21:42 |
bencoh | just "enhancing" human voice | 21:42 |
bencoh | (well, more amplifying than enhancing) | 21:42 |
KotCzarny | more like constant filter up to ~800hz, then linear catch up to no-filter at 2khz | 21:42 |
bencoh | freemangordon: what about it? | 21:43 |
KotCzarny | bencoh, look at the scale | 21:43 |
*** xorly has joined #maemo | 21:43 | |
KotCzarny | at 2khz they both are -30db | 21:43 |
freemangordon | also, we don;t know the electro-acoustic parameters of the speakers and their case, so we don;t really know what is the real output | 21:43 |
bencoh | true | 21:43 |
freemangordon | :nod: | 21:43 |
KotCzarny | also, if you manage to find speakers that fit with almost no hacking into n900 that are without the flaw, it would be cool | 21:45 |
freemangordon | Butterworth filter? | 21:45 |
freemangordon | but I don;t have the phase response to judge with certainty | 21:47 |
freemangordon | not to say it was a while I was student :D | 21:47 |
KotCzarny | if you keep learning, you just go on a self-directed student program | 21:48 |
*** erlehmann has joined #maemo | 21:49 | |
freemangordon | the point is that I knew lot of this stuff (analog/digital filters, freq/phase diagrams, poles, etc, etc), but seems I have forgotten most of it | 21:50 |
DocScrutinizer05 | freemangordon: ((most-probably they have had the same/similar problem with some other device)) hardly, iirc they developed XPROT in a hurry while delaying shipping of N900 since they found out "the speakers will break on your device, and you don't want that to happen. So please stay patient until we deliver the fixed device to you" <quote Nokia hotline to me> | 21:51 |
bencoh | I hope we'll be able to build a make a brain snapshot someday | 21:51 |
bencoh | (not really hoping, but .... that'd be cool) | 21:51 |
KotCzarny | bencoh, pray that we will not | 21:52 |
KotCzarny | otherwise humans will get annihilated | 21:52 |
freemangordon | DocScrutinizer05: could be, who knows. but still, I think the filter code and coil temp prediction was borrowed from somewhere else and just adopted | 21:53 |
DocScrutinizer05 | that's possible, and they used an academic model that counts in irrelevant environment 'variables' like "ambient temperature" from BME | 21:54 |
freemangordon | my point exactly | 21:54 |
bencoh | the only feedback it gets is temperature? | 21:57 |
DocScrutinizer05 | bencoh: ((isn't it more of a bandpass)) no, it's a highpass that cuts below some 800(?)Hz and finally applies linear attenuation below 400(?) HZ | 21:57 |
freemangordon | bencoh: there is no feedback | 21:58 |
bencoh | :D | 21:58 |
DocScrutinizer05 | freemangordon: ^^^, using white noise instead of pink noise would yield more legible diagrams | 21:58 |
DocScrutinizer05 | ;-) | 21:58 |
bencoh | then I really dont understand | 21:58 |
bencoh | +1 for the white noise | 21:58 |
*** peterleinchen has joined #maemo | 21:59 | |
freemangordon | DocScrutinizer05: iirc it was you who wanted freq response diagram for pink noise :D | 21:59 |
bencoh | :D | 21:59 |
DocScrutinizer05 | bencoh: just tilt your head 45° to the right before watching both diagrams | 21:59 |
DocScrutinizer05 | freemangordon: yes, but *I* can read it ;-) | 22:00 |
freemangordon | that's why I provided it, for you to read it :P | 22:00 |
DocScrutinizer05 | and pink noise is way more 'natural' so any dinamic parameters in XPROT will adjust to more natural usual values with pink | 22:01 |
DocScrutinizer05 | freemangordon: for bencoh you could provide a drived plot: $output - $input | 22:02 |
freemangordon | or he can just grab those 2 .raw files and feed audacity with them ;) | 22:02 |
DocScrutinizer05 | logarithmic X and Y scale | 22:02 |
KotCzarny | and then drop the base | 22:03 |
freemangordon | and he can even feed matlab with the data to recover the transfer function :D | 22:03 |
KotCzarny | i dont remember which freq pattern resulted in constant cone displacement | 22:03 |
KotCzarny | maybe feed some signal with non zero dc? | 22:04 |
DocScrutinizer05 | bencoh: the filter has a __/'''''''''' characteristic, with __ being some -20dB or whatever, and "/" between ~400 and ~800Hz | 22:04 |
bencoh | DocScrutinizer05: :-)) | 22:04 |
DocScrutinizer05 | bencoh: in "output" draw a line on left "\" and a parallel line on right "\" you then consider the right line to be the X-axis with a Y of 0dB | 22:06 |

DocScrutinizer05 | laymen's plot analysis | 22:06 |
bencoh | DocScrutinizer05: riiight, but as freemangordon said I'd prolly rather go through the audacity process :) | 22:07 |
DocScrutinizer05 | oops, the two corner frequencies are 2000Hz (upper) and ~750Hz (lower) | 22:08 |
DocScrutinizer05 | for the "/" section of the filter | 22:08 |
DocScrutinizer05 | below 750Hz it applies a constant attenuation of around -6dB | 22:09 |
freemangordon | bencoh: input is 32bit, output is 16bit. IIRC | 22:10 |
DocScrutinizer05 | with this particular input parameters like volume, coil temperature etc | 22:10 |
freemangordon | or input is stereo 16bit, output is mono | 22:10 |
freemangordon | left channel only | 22:10 |
*** Sicelo009N has joined #maemo | 22:11 | |
DocScrutinizer05 | it would be way more interesting to test burst impulse response over time or volume sweep over time, e.g. for an input consisting of a 5 seconds pink noise +6dB burst or a input sweep from -infinity to +9dB over a 20s | 22:16 |
DocScrutinizer05 | and then all the way back during next 20s | 22:16 |
DocScrutinizer05 | and have the output plotted as 3D-graph | 22:16 |
DocScrutinizer05 | or as color map, or whatever | 22:17 |
DocScrutinizer05 | X:time Y:freq Z:amplitude | 22:17 |
*** _rd has joined #maemo | 22:17 | |
freemangordon | yeah, that should reveal how HFP is tuned with input volume and freq | 22:17 |
KotCzarny | and temperature! | 22:17 |
KotCzarny | :) | 22:17 |
freemangordon | yes | 22:17 |
freemangordon | and temperature... which is never close to the reality :D | 22:18 |
KotCzarny | hotairstation to the rescue | 22:18 |
bencoh | hmm | 22:19 |
bencoh | KotCzarny: I dont really think we need to test that on a real device :p | 22:19 |
freemangordon | test what? | 22:21 |
freemangordon | we can't measure coil temp | 22:21 |
KotCzarny | i wonder what would happen to the audio when fake bme would report 100C | 22:22 |
freemangordon | iirc I tested various temperatures (fake), don;t recall something spectacular | 22:23 |
freemangordon | KotCzarny: but I can provide the code I used to test xprot, if someone is interested | 22:24 |
DocScrutinizer05 | ohmy, are people going to TEST an irrelevant parameter like ambient temperature now? | 22:25 |
DocScrutinizer05 | I suggest to completely kick out the temperature parameter and replace it by a constant of 55°C | 22:26 |

Sicelo | DocScrutinizer05: how much do you think shipping an N900 from Germany to South Africa would cost? rough estimate? | 23:04 |
erlehmann | rtcom-messaging-ui seems weird | 23:17 |
*** ced117 has quit IRC | 23:20 | |
klopsi-u3 | Sicelo: the german n900s don't have 4 arrow keys | 23:22 |
Sicelo | still an N900 :) | 23:30 |

Sicelo | oh god! so i'm in zone 4 .. that means EUR41.99? | 23:35 |
erlehmann | how can i get the source for telepathy-gabble? | 23:37 |
Sicelo | erlehmann: apt? what is weird with messaging ui btw? | 23:38 |
erlehmann | Sicelo it is written in html and js | 23:38 |
DocScrutinizer05 | http://wstaw.org/m/2015/11/24/plasma-desktoprN3616.png | 23:38 |
DocScrutinizer05 | Sicelo: ^^^ | 23:39 |
erlehmann | Sicelo how do i get the source with apt? | 23:40 |
erlehmann | > 504 Host wstaw.org lookup failed: Host not found | 23:40 |
DocScrutinizer05 | o.O | 23:41 |
DocScrutinizer05 | WFM | 23:41 |
Sicelo | thanks DocScrutinizer05. seems much more reasonable. the N900 is from someone who does not need it anymore .. he's willing to give it to me for free (sans shipping), if no one else comes up with a price | 23:42 |
erlehmann | i want to make rtcom-messaging-ui show images in xmpp messages. can someone help me where to start? | 23:43 |
erlehmann | or is there an xmpp client that can do images in xmpp messages? | 23:43 |
Sicelo | needless to say, i wish no one makes an offer, haha :D | 23:43 |
erlehmann | lel why | 23:43 |
Sicelo | then i get it | 23:44 |
erlehmann | i understand. what about message receipts? | 23:44 |
Sicelo | erlehmann: i think Pali fixed your MUC stuff? so he should know more .. and since he was able to fix it, i surmise that source is available. try `apt-get source rtcom....` | 23:44 |
erlehmann | ah | 23:45 |
*** capitanocrunch has joined #maemo | 23:45 | |
DocScrutinizer05 | for scripting languages like HTML (incl JS) it seems to me the program is the source | 23:47 |
DocScrutinizer05 | well, almost | 23:49 |
erlehmann | DocScrutinizer05 the point is that i want to patch telepathy-gabble and have no idea where to start | 23:50 |
erlehmann | like where do i get the current source for maemo gabble? | 23:50 |
*** futpib_ has joined #maemo | 23:50 | |
*** futpib has quit IRC | 23:52 | |
erlehmann | used this http://maemo.org/development/sources/ | 23:53 |
erlehmann | i was like „apt-get source telepathy-gabble“ | 23:54 |
*** _rd has quit IRC | 23:54 | |
Fulltux | you can ddl the tar.gz http://repository.maemo.org/pool/maemo5.0/free/t/telepathy-gabble/ | 23:59 |
