| lardman | dragly: I don't suppose you're about...? | 00:21 |
|---|---|---|
| dragly | I'm here | 00:31 |
| dragly | just wish I had a notification plugin for irssi over screen over ssh :-p | 00:31 |
| lardman | :) | 00:33 |
| lardman | np | 00:33 |
| lardman | so what is the crash I've managed to cause out of interest? | 00:33 |
| lardman | that's the problem with coding in the wee hours and deciding to check-in anyway (/me ducks for poor form) | 00:34 |
| dragly | haha. No worries. I do the same way too often. | 00:35 |
| *** tbf has quit IRC | 00:35 | |
| dragly | It crashes when clicking "Scan" | 00:35 |
| lardman | segfault? | 00:35 |
| dragly | actually segabort | 00:35 |
| lardman | oh Scan, that's not so good | 00:35 |
| dragly | never heard of it before | 00:35 |
| dragly | GST error: gstfilesrc.c(1044): gst_file_src_start (): /GstPipeline:test-camera/GstFileSrc:file_src | 00:35 |
| lardman | hmm, well that's perhaps because there's no valid file source set | 00:36 |
| lardman | but if you click scan it should select the camera source | 00:36 |
| lardman | hmm | 00:36 |
| lardman | strange, I think the code is right, or at least as right as I could guess for the lack of examples | 00:39 |
| dragly | I tried running it in gdb, but I didn't get any info about the faulty line. | 00:40 |
| dragly | but it inits correctly at least | 00:41 |
| lardman | is strange, because when you hit "Scan" it should set the camera as the source | 00:41 |
| lardman | or rather the scaler which is attached to the camerasrc | 00:42 |
| dragly | where is this? | 00:42 |
| dragly | in mainwindow.cpp? | 00:42 |
| lardman | mainwindow.cpp calls a fn in videowidget.cpp | 00:42 |
| lardman | void MainWindow::startScan() -> videoWidget->useVideosrc(); | 00:43 |
| dragly | useVideosrc is not defined in videoWidget.cpp | 00:44 |
| dragly | oh wait | 00:44 |
| dragly | I might be wrong | 00:44 |
| lardman | I think it is | 00:44 |
| lardman | is here anyway | 00:44 |
| dragly | my bad, searched the wrong file :) | 00:44 |
| lardman | you would get a compile error otherwise ;) | 00:45 |
| lardman | lcuk: ping | 00:45 |
| dragly | I'd think so too :p | 00:45 |
| lardman | lcuk: I don't suppose your gst source has any pointers to example code for input-selector? | 00:45 |
| dragly | maybe it is something wrong with video_crop? | 00:45 |
| lardman | was working before I stuck the input-selector in there | 00:45 |
| lardman | but the error mentions the filesrc, which is odd | 00:46 |
| lardman | perhaps it requires a valid filename when the pipeline is started, no matter if it's connected or not? | 00:46 |
| lardman | might need a dummy file in there | 00:47 |
| lardman | e.g. call videoWidget->useFilesrc(fileName); with a valid file around line 154 of videowidget.cpp? | 00:48 |
| dragly | I could try that | 00:49 |
| lardman | I'm doing some (day job) work atm under WinXP I'm afraid, but can try in a while | 00:50 |
| dragly | where fileName is just "dummy" or something? | 00:50 |
| lardman | needs to be a valid filename actually | 00:50 |
| lardman | so something that the pipeline can read in, e.g. some gif/jp(e)g/png/bmp/etc | 00:50 |
| lardman | if that's the problem we could ship a microsized png with the package, or point it at one of the icons even ;) | 00:51 |
| dragly | i'll try pointing at an icon then :) | 00:51 |
| lardman | it will probably decode that though! | 00:51 |
| lardman | :) | 00:51 |
| lardman | but go for it :) | 00:52 |
| dragly | Program received signal SIGSEGV, Segmentation fault. | 00:53 |
| dragly | 0x409cd99c in g_type_check_instance_cast () from /usr/lib/libgobject-2.0.so.0 | 00:53 |
| dragly | only added useFilesrc("/usr/share/icons/hicolor/14x14/hildon/general_alarm_on.png"); to line #154 | 00:54 |
| dragly | seems like g_object_set might be the sinner here | 00:55 |
| lardman | hmm, strange | 00:57 |
| lardman | well I guess commenting out the offending lines might be the best bet in the short term then | 00:58 |
| lardman | and I'll try to debug it over the weekend | 00:58 |
| *** t-tan has quit IRC | 00:58 | |
| dragly | okay. I'll do that for now then. | 01:01 |
| lardman | sorry for the bother | 01:02 |
| dragly | no worries. Glad you tried :) I would have had no idea were to start. I guess I'd start looking for zbar's file loading examples :D | 01:02 |
| lardman | add return to the Open Image callback so it does nothing, comment out the videoWidget->useVideosrc(); call in the Scan callback, alter the pipeline setup so the input-selector isn't added to the pipeline | 01:03 |
| lardman | last bit, i.e. comment out lines 256/257 in videowidget.cpp and change line 261 so s/input_selector/video_crop | 01:05 |
| lardman | should do the job (he says ;)) | 01:06 |
| lardman | probably ok to create the objects and add them, as I will try to get it working at the weekend | 01:06 |
| lardman | but that should at least stop them from being linked together | 01:06 |
| dragly | hm.. can't really seem to get it working correctlyg | 01:13 |
| *** lbt has quit IRC | 01:14 | |
| lardman | drat | 01:15 |
| lardman | pipeline not setting up correctly now? | 01:15 |
| dragly | not sure. I'm looking at the diff now | 01:17 |
| dragly | there! Got it :) | 01:18 |
| lardman | cool :) | 01:19 |
| lardman | well done | 01:19 |
| dragly | thanks for the help :) | 01:20 |
| dragly | I'll upload it to extras-devel | 01:20 |
| lardman | thanks | 01:20 |
| lardman | I'll have some time on Friday so will see if I can work out what's up with the filesrc stuff and also look at Python plugins | 01:21 |
| lardman | how's your plugin coming along anyway? | 01:22 |
| dragly | pretty good. It works as a testing version for now. | 01:23 |
| lardman | good news :) | 01:24 |
| dragly | Will do some more testing before I add functionality I guess. Would like to get some input from others as well. | 01:24 |
| lardman | I need to sit down and write a db app in Python once I get those plugins working | 01:24 |
| lardman | are you going to release it too? | 01:24 |
| lardman | at the same time | 01:24 |
| dragly | It is already released :) mbarcode is dependent on it | 01:25 |
| lardman | ah ok | 01:25 |
| lardman | :) | 01:25 |
| dragly | I've been incrementing the version numbers a couple of times now, by the way. mbarcode is now 0.1.3. Hope you don't mind :) | 01:26 |
| *** Ken-Young has joined #maemo-devel | 01:29 | |
| lardman | no, no problem whatsoever | 01:29 |
| dragly | and feel free to make the mbarcode no longer depend on mbarcode-plugin-ii in the future if it should break or anything. I just wanted to add it as a dependency to get some more input from others. | 01:30 |
| dragly | brb, heading out for a couple of minutes | 01:30 |
| lardman | that's fine, eventually we'll have to sort out how we deal with the deps, but sounds fine for the time being | 01:31 |
| lardman | cool ok, am heading for bed soon | 01:31 |
| lardman | cheers for the good work :) | 01:31 |
| ecksun | how would i go about finding more information (like a reference) detailing dbus-events? | 01:32 |
| ecksun | for example, how can i get some more information about this: | 01:32 |
| ecksun | signal sender=:1.17 -> dest=(null destination) serial=799 path=/com/nokia/phone/net; interface=Phone.Net; member=signal_strength_change | 01:32 |
| lardman | might be in the ml | 01:32 |
| ecksun | the ml? | 01:32 |
| lardman | mailing list | 01:32 |
| lardman | or actually I think there was a wiki page that listed dbus calls | 01:33 |
| ecksun | yeah, thats more what Im looking for | 01:33 |
| lardman | dunno the link tho, but search should find it I imagine | 01:33 |
| ecksun | yeah, I have found bits of what Im searching for | 01:34 |
| ecksun | but I was hopeing there were some page where all calls/signals where listed and what they actually did | 01:35 |
| lardman | no, the calls are actually internal and not generally published, though there's a push for them to be | 01:35 |
| lardman | s/internal/for internal use | 01:35 |
| ecksun | i see | 01:35 |
| lardman | do have a search of the maemo-developers ml tho, and if there's not what you want there just ask | 01:36 |
| ecksun | yes, will do that | 01:36 |
| ecksun | thank you | 01:36 |
| lardman | np | 01:36 |
| lardman | and do push for a wiki page/api pages with list of these things too :) | 01:37 |
| ecksun | would love to, any specific way to make your voice heard? :) | 01:38 |

| lardman|home | [lardman] well just add it to the bottom of you email if you have to send one, otherwise I think we just need to build a critical mass and then create a justification page on the wiki to sell the idea to Nokia | 01:40 |
