| Lullen | Anyone hot any idea how to debug a maemo program without a phone? | 15:27 |
| lcuk | Lullen, in scratchbox you can build with x86 and run inside xephyr? | 15:32 |
| lcuk | or arm version also | 15:32 |
| lcuk | and can debug from there? | 15:32 |
| lcuk | or if you wrote using the nokia qt sdk theres an emulator/simulator there | 15:32 |
| Lullen | the simulator do not like QMaemo5ValueButton and dbus etc | 15:33 |

| lardman | no-one knows about QDBus? :( | 17:38 |
| lardman | Anyone know how I check if mBarcode is correctly registered with DBus? | 18:11 |
| lardman | hmm, dbus-monitor | 18:13 |
| lardman | and it appears we are correctly registered | 18:13 |
| lardman | so why does hildonmime not want to work? | 18:13 |

| lcuk | lardman, eep | 19:24 |
| lardman | hey lcuk | 20:12 |
| lcuk | whats hildonmime meant to be doing that its not | 20:13 |
| lardman | right, onto other questions - I'd like external apps to register themselves as wanting to receive DBus messages, I suppose I could get them to call a DBus method on mBarcode when they install/run, but this will start mBarcode | 20:13 |
| lardman | are there any other centralised settings services I could use and have mBarcode read when it starts up? | 20:14 |
| lardman | GConf I suppose? | 20:14 |
| lcuk | lardman, i dunno, i havent actually used dbus | 20:15 |
| * lcuk is not the font of all knowledge :P but i bet someone over there knows >>> | 20:16 | |
| lardman | yeah, don't worry, wasn't aimed directly at you lcuk! :) | 20:16 |
| lcuk | good | 20:16 |
| lcuk | :D | 20:16 |
| lcuk | i broke liqcam | 20:16 |
| lardman | Basically mBarcode now broadcasts a message over DBus saying "I've found a barcode, it's this type and this is the content" | 20:17 |
| lardman | so apps can hook into that and use it | 20:17 |
| lardman | but some apps might want to be woken/started-up if a certain type of barcode is detected, so I was thinking they should register their interest (barcode type) | 20:18 |
| lardman | and then mBarcode will consult the registration list every time a barcode is scanned, and send out a specific DBus message to each of the registered apps | 20:18 |
| lcuk | http://liqbase.net/liq.20100703_181352.cameraui.scr.png | 20:18 |
| lardman | these messages will start said apps if necessary | 20:18 |
| lcuk | cool! | 20:18 |
| lardman | the question is how to do the registration | 20:19 |
| lcuk | the registration isnt done by you though is it | 20:20 |
| lcuk | its opening the right app | 20:20 |
| lcuk | ahhh i see | 20:20 |
| lardman | well the apps in question will need to do something, either register everytime they start up, or when installed | 20:20 |
| lcuk | not just opening one type of app, its a group | 20:20 |
| lardman | either way, probably best that mBarcode itself isn't started just to handle the registration | 20:21 |
| lcuk | would the app in question always want to be brought up whilst you are scanning? | 20:21 |
| lcuk | or would you want it to come up at the end | 20:21 |
| lcuk | after you have built up your tillroll | 20:22 |
| lcuk | when the user clicks on a barcode, open the app | 20:22 |
| lardman | it would be presented on the plugins list like the built-in plugins, then foregrounded/started by pressing the button | 20:22 |
| lcuk | is another stable opportunity | 20:22 |
| lcuk | think, you will potentially want bulk input | 20:22 |
| lcuk | running over your music albums | 20:23 |
| lcuk | or books | 20:23 |
| lardman | maybe, maybe not though | 20:23 |
| lcuk | you dont want to dismiss a book thing | 20:23 |
| lcuk | once per barcode | 20:23 |
| lcuk | (in other situations, you might) | 20:23 |
| lardman | quite, but filling the db can be done in a separate way | 20:23 |
| lcuk | yup | 20:23 |
| lardman | I was wondering whether writing the itemdb as a Python standalone app would be better, then having it listen for the barcode scanned messages to fill the db | 20:24 |
| lardman | and when running in anger, have it register to be told about EAN/ISBN barcodes and started as an external plugin | 20:24 |
| lcuk | what if the user wants to scan his historical photographs for barcodes or identification features | 20:25 |
| lardman | as in all at once? Or a single item? | 20:25 |
| lcuk | i have over 1000 photos on my n900 | 20:26 |
| lardman | ah, you mean the ones that have already been recorded? | 20:26 |
| lcuk | ive taken photographs of quite a few barcodes! | 20:26 |
| lardman | saved even | 20:26 |
| lcuk | yeah | 20:26 |
| lcuk | can mbarcode run over all of them | 20:26 |
| lcuk | and give me a list? | 20:26 |
| lcuk | of everything it found | 20:26 |
| lardman | well you will soon be able to open them one-by-one | 20:26 |
| lcuk | theres codes on all my plane tickets | 20:26 |
| lardman | but no, not atm, and that's also not in the plan - what is the use-case? | 20:26 |
| lcuk | and all my train tickets | 20:26 |
| lcuk | and on signposts and albums ive liked | 20:27 |
| lardman | of course, but usually you'd scan those as you see them, not all at once | 20:27 |
| lcuk | just seeing what ive seen | 20:27 |
| lcuk | well - ive got the data | 20:27 |
| lcuk | it just needs processing | 20:27 |
| lardman | libzbar + libdmtx | 20:27 |
| lcuk | i can reassemble things based on the data ive stored :) so getting on a plane at this date etc | 20:27 |
| lardman | not what mBarcode is designed for though | 20:27 |
| lcuk | well i was in a GTD mood | 20:28 |
| lcuk | store the data and process another time :D | 20:28 |
| lcuk | its been long enough now lol - ive probably got some trips i havent claimed expenses for ! | 20:28 |
| lardman | it would be trivial to write a program which scans a dir for photos, opens each one into e.g. a QImage, scans with libzbar + libdmtx and writes the result to a file | 20:28 |
| lcuk | cool | 20:29 |
| lardman | not so trivial trying to get lists of photographs to be passed down the gst pipeline in mBarcode | 20:29 |
| lcuk | and those libraries are now on the machine | 20:29 |
| lcuk | ok reasonable enough dude | 20:29 |
| lcuk | but i can give you yuv data direct | 20:29 |
| lardman | I can give you some code to scan them if you want? | 20:29 |
| lardman | if you want to hook it into liqbase for example? | 20:29 |
| lardman | I can't see that specific use-case being useful for many people | 20:30 |
| lardman | but if it turns out to be, then I'm happy to take a look at it | 20:30 |
| lcuk | cool! | 20:30 |
| lcuk | so if i make a tiny liqbase project with it ill put it on github which has entry for detection | 20:31 |
| lardman | I'd quite like to be able to hook into the camera, so you have an extra button to "Scan for barcodes" | 20:32 |
| lcuk | and ill talk to you more from there, the image selector has code, ill finish making it multiselect | 20:32 |
| lardman | which would then broadcast a DBus message | 20:32 |
| lcuk | lardman, :) ive always wanted a barcode button | 20:32 |
| lardman | s/camera/built-in camera app | 20:32 |
| * lcuk nods | 20:32 | |
| lardman | lcuk: bend some arms in and amongst the Nokians ;) | 20:32 |
| lardman | would be good to be able to add random plugins to the camera app in fact | 20:33 |
| lcuk | yeah facial recognition is something im keen on | 20:33 |
| lcuk | as well as multibarcode | 20:33 |
| lcuk | i know its feasible | 20:33 |
| lardman | then again, might be better to re-write it ourselves, in which case we need to unhook the shutter release and shutter cover from the built-in app | 20:33 |
| lcuk | i just leave my shutter open nowadays | 20:34 |
| lardman | multibarcode is probably handled by zbar and dmtx already | 20:34 |
| lardman | in fact I'm pretty sure it is | 20:34 |
| lcuk | liqbase has a camera button on the file select dialog | 20:34 |
| lcuk | that screenshot i shown is from there | 20:34 |
| lcuk | the file select you saw a couple of days ago that is | 20:34 |
| lcuk | the very very fast one | 20:34 |
| lardman | there was some talk a while back about writing a replacement camera app wasn't there? | 20:34 |
| lcuk | ;) | 20:34 |
| lardman | and being able to insert custom filters/etc in the pipeline, did that die? | 20:34 |
| lardman | lcuk: unless it's the app that is started when you open the shutter cover/press the shutter release it's still a pita | 20:35 |
| lardman | I find that now with mBarcode | 20:35 |
| lcuk | yeah | 20:35 |
| lcuk | but as a halfway house i just leave it open during testing | 20:36 |
| lardman | yeah same here | 20:36 |
| lardman | but it being part of the official/normal camera app would be better imho | 20:36 |
| lardman | or at least having some way of selecting which is started up | 20:36 |
| lardman | out for food, bbl | 20:38 |
