[14:10] hi [14:10] is there a (very) simple example on how to create a c++ + qtquick app? [14:11] preferrably something that works in qtcreator as well [14:21] ohmy: you should learn how qtmultimedia integrates with qml. You've already done good by implementing a QAbstractVideoSurface [14:23] you don't want to get a QImage (which is not on the GPU). Instead it is better to put the webcam frame into a texture on the GPU, which then QtMultimedia & QML can render [14:24] greyback: sure, the thing is that i need a way to view theses images in two (or more different) windows, reason why i'm not using the camera element of QML [14:25] greyback: and i'm nnot OpenGL expert, i really just need to grab these frames and show them in two separate qml containers [14:25] greyback: do you know any example that can helps me ? [14:25] ohmy: you need to view the live webcam output in 2 separate places simultaneously? Or a live view in one, and a static frame in another [14:26] greyback: two live in 2 separate QML containers at the same time (same PC) [14:29] ohmy: hmm, I suggest you investigate 2 channels. One is to try writing a qml test file using QtMultimedia to play a video [14:29] https://developer.ubuntu.com/api/qml/sdk-14.10/QtMultimedia.VideoOutput/ [14:30] and then modify it to see if you can have two VideoOutputs using the same MediaPlayer as their source [14:30] if that works, I suggest you continue your work and integrate your webcam as a backend for qtmultimedia [14:31] greyback: im trying, AFAIK you can only have one VideoOutput :( but i'm trying, thanks a lot [14:32] ohmy: if you are indeed correct, you'll have a tougher time of it. You'll need to write a custom QQuickItem do to the job. [14:33] greyback: thanks a lot [14:59] ohmy: this might interest you: http://pastebin.ubuntu.com/11836175/ [15:00] ohmy: it shows the video twice on screen. It's not the most efficient approach however [15:00] but it might be enough for you [15:16] greyback: te first approach does not look to work :( bool QDeclarativeVideoOutput::createBackend(QMediaService*) Media service has neither renderer nor window control available. [15:16] greyback: thanks a lot trying this one [15:17] ohmy: that error I think has more to do with qtmultimedia not finding a backend which can play the media [15:17] greyback: i see [15:18] greyback: it happends only when i use a second VideoOutput [15:18] hmm [15:18] ok, well see my pastebn above. It uses only 1 VideoOutput, but displays is twice [15:18] greyback: i saw shader trick, its very nice, the thing is that i need to show the videos in two separate windows [15:18] oh windows [15:18] greyback: yes i understood [15:19] still might be do-able [15:19] greyback: yes windows/rectangles [15:21] greyback: thanks a lot for your time, really appreciated, i'm stuck since few hours now [15:22] ohmy: http://pastebin.ubuntu.com/11836259/ [15:22] proves the shader trick works across windows [15:22] since it's using an FBO in the background [15:30] greyback: thanks so much, i'm trying to understand why its not working on my PC [15:31] greyback: QQuickItem: Cannot use same item on different windows at the same time. [15:31] ohmy: I'm using qt5.4 on vivid. [15:31] to make video playback work, I had to install one of these: https://launchpad.net/~mc3man/+archive/ubuntu/gstffmpeg-keep/+packages [15:44] greyback: sure i have already gstreamer ffmpeg [15:44] greyback: on video is displayer but the other window is white [15:45] greyback: its probably the way im loading qml's [15:45] ohmy: I just load that file with "qml" [15:46] greyback: sure im using QQmlApplicationEngine load [15:50] greyback: it works perfectly, im trying now to change MediaPlayer and use Camera element [15:50] greyback: really thanks [15:50] ohmy: welcome! === chihchun is now known as chihchun_afk [16:43] what channel do i need to flash to get the wily branch? [16:44] ubuntu-touch/devel-proposed/ubuntu?

[17:29] dubstar_04, that should get you wily [17:29] even just ubuntu-touch/devel/ubuntu should [17:33] balloons, thanks. [17:45] how much of this is still good: https://docs.google.com/document/d/1jgn1nJeBjgQO3RzDMZ44wM606u6u02U6bVgtaSHkUA0/edit ? [17:56] popey, is there any other purpose other than crediting the authors for https://code.launchpad.net/~popey/music-app/add-authors/+merge/263910 ? .. eg a hook in click to link to this and then display the authors in the copyright info in system-settings? [17:57] ahayzen: two fold, thanking, but also, I want to link to it from a website [17:57] rather than have a list of contributors on the website [17:57] because the list is long and it makes the page look bad :) [17:57] popey, ah cool :-) hopefully we'll be able to have a hook in click/snappy one day :-) [17:57] yeah! [17:59] popey, did you auto generate this from the bzr history ? [17:59] yes [17:59] also, sed, sort, uniq etc [17:59] sweet \o/ [18:02] might get the new icon in soon, wonder if anyone will notice the music one, it's quite subtle [18:02] probably won't...i hardly did lol [18:02] heh [18:02] i had to double check it was the new one :) [18:02] popey, after https://code.launchpad.net/~ahayzen/music-app/fix-1470755-playlist-0-append/+merge/263707 i sense us wanting to land a click anyway [18:02] which must mean the old one was already awesome [18:02] hey all is "delegate: Subtitled " dead [18:02] ? [18:03] ahayzen: that would be great, post OTA5 [18:03] popey, it'll hopefully be in tonight, just some OCD from me/victor in the comments at the moment :-) [18:03] haha [18:04] ahayzen: ^ [18:05] zsombi, hi, have you been able to look at bug 1469471 and bug 1468100 both are related to the new listitems and the first is blocking it from landing in music [18:05] bug 1469471 in ubuntu-ui-toolkit (Ubuntu) "Checkbox shown in the ListView Multiselect mode does not obey selected property" [Undecided,Confirmed] https://launchpad.net/bugs/1469471 [18:05] bug 1468100 in ubuntu-ui-toolkit (Ubuntu) "ListItems with trailing but no leading actions, after swiping right break selectMode" [Undecided,Confirmed] https://launchpad.net/bugs/1468100 [18:06] ahoneybun, https://developer.ubuntu.com/api/apps/qml/sdk-15.04/Ubuntu.Components.ListItems.Subtitled/ ? [18:07] Subtitled is not a type [18:07] the SDK says [18:07] I'm following a old guide so it might be that [18:07] ahoneybun, check the import is right [18:08] import QtQuick.XmlListModel 2.0 ? [18:08] import Ubuntu.Components.ListItems 1.0 [18:09] weird [18:09] OMG Neverball is working on mako! .. see you next week folks i've got some gaming todo lol [18:09] so it does not like the "as ListItem" at the end anymore [18:09] lol [18:09] yay it work!!!! [18:10] ahoneybun, if you were using as ListItem then you need todo ListItem.Subtitled { [18:10] * ahoneybun is making a Full Circle Mag app [18:10] trying anyway === dpm is now known as dpm-afk [18:34] ahayzen: / [18:34] http://pastebin.ubuntu.com/11837276/ [18:35] it is telling me ArticleContent is not a type [18:38] ahoneybun, where is the file ArticleContent.qml ? [18:38] it is not a file [18:38] oh [18:38] right naming crap [18:39] also the curly braces situation at the bottom looks fun [18:39] ? [18:39] L60-66 look like they have appeared overtabbed... probably just the conversion to pastebin [18:40] same here [18:41] something that the SDK did I think [18:42] yeah just ignore it, just some minor OCD on my behalf :-) [18:42] works all well now [18:42] thanks ahayzen [18:43] no problem :-) [18:43] ahayzen: now I have a working feed from the Full Circle Mag in my app :) [18:45] sweet \o/ [18:45] now to work on the Issues tab... [18:45] no clue on how that would work [18:46] ahayzen: http://imgur.com/yQGJtbr [18:47] ahoneybun, i gtg will be back later if your still having issues [18:49] ok [18:49] thanks [18:58] ahayzen: no, I did not, but I'll check 'em asap!!! [19:00] ahayzen: nice catches btw!!!

We were supposed to work only with list not with list
