[Development] Qt 5.0.2 RC -- Release Testing
Hi, Qt 5.0.2 RC release testing has been started. We would like to kindly ask the Qt Community for help by testing the new packages. 1. Installer packages are available here: http://releases.qt-project.org/qt5/5.0.2-rc1/ 2. Known issues are available here: http://qt-project.org/wiki/Qt502KnownIssues 3. Qt bug reports should be reported in JIRA: https://bugreports.qt-project.org/ 4. Please report your testing effort via http://testresults.qt-project.org/forms/release-testing/ ? There is about 600 improvements in Qt 5.0.2 compared to Qt 5.0.1. We believe it will address many of the issues that have hindered the users of Qt 5.0.0 and Qt 5.0.1. Naturally there is always more bugs to fix and we plan to provide more fixes new features in Qt 5.1.0. So please check carefully Qt 5.0.2 release candidate so that Qt 5.0.2 final release carries us there.

Since GCC 4.8 is not released yet, I can't make the case for it being a P1. I fully disagree with that :). I think compile fixes for compilers that are not released yet qualify. But what's done is done, and you can disagree with what I think too. The 'not released' compiler became 'the released compiler', by the way. So unless d9ff510f02bba63dabe7a081a68296056a89ae4c is cherry-picked to the release branch, 5.0.2 will not build with GCC 4.8, right? Backport and add one Ossi and/or Sergio to the reviewers list. If there's still time for the release, it will be applied. Sorry, I don't have GCC 4.8 to test the result of backporting the patch with. My mail wasn't an attempt to get the fix in, but was to draw attention to the fact that compile fixes even for unreleased compilers should always go in the release branch if applicable there. What happens this time with 5.0.2 and GCC 4.8.0 doesn't matter as much as the 'community understanding' of where to put things like this. I still think that the patch should have been rejected on stable until it was in release instead. Even if 5.0.2 was released before GCC 4.8.0, that would still mean that they would be incompatible. That's a good reason it should have been in the release branch in the first place. Have you changed your mind on that? Why does the release of 4.8.0 change anything? No matter which project was released first, they would always be incompatible as a result of the patch going into stable instead of release.

[Development] [GSTREAMER/QML] How to pass custom options from qml to gst
Hi everyone, I don't know if this is the right place to ask this question, but I cannot find better ML than this, so, if you know a better ML to ask, please tell me and sorry. I've a gstreamer 0.10.36 installation on my board and it's hw accelerated, now I'm trying to make some test with QtMultimedia5 and the Video element inside QML. The video element with my video test don't work out of the box, so I'm asking you if there is some particular method to pass some extra parameter to the gstreamer for playing the video. I've some particular command for the gst pipeline like nv_omx_videosink and other nvidia related things that the default video element can't know. So, how can I play a video embedded in a qml file thru gst? Thank you. --- Matteo Brichese Software Engineer mbrich...@came.it Came Cancelli Automatici S.p.A. www.came.com ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development

I don't think the problem was in our code.
I beleive GCC 4.8 Is wrong.
The C++11 standard § 7.5.1 1 says:
[ Note: An explicit specialization can differ from the template declaration
with respect to the constexpr specifier. — end note ]
Which I read that this explicitly allows code like this:
templatetypename T constexpr int foo(T) { return 0; };
template int foo(int) { return 1; }
So the bug should be reported to GCC if it still do not compile with the 4.8
release.
(Note: this does not mean it was a bad idea to work around the bug)

Re: [Development] R: [GSTREAMER/QML] How to pass custom options from qml to gst
Hi, As far as i know Qt uses in QtMultimedia fakesink and xvideosink for gstreamer pipeline. If you want to use custom videosink you should create your own Qml plugin. There are some examples on the web: http://imxcv.blogspot.com/2012/03/video-to-texture-streaming-part-2-imx6.html This above creates fakesink to catch frame from custom videosink. You can create such pipeline in your own custom QML element (Video) and draw each frame received from gstreamer in paintEvent. Look at sources of QtMultimedia to see how it is implemented. Simply changing xvideosink to your HW accelerated videosink should resolve your problem. -- Regards, Tomasz Olszak 2013/3/27 Matteo Brichese mbrich...@came.it On Wed, Mar 27, 2013 at 8:27 AM, Matteo Brichese mbrich...@came.it wrote: Hi everyone, I don't know if this is the right place to ask this question, but I cannot find better ML than this, so, if you know a better ML to ask, please tell me and sorry.

You can create your own video surface using gstreamer, add whatever you want (support for gstreamer parameters) to it. It should be not the best practice but it should work any way. There is some examples from Qt5 docs that demostrate how to create custom video surfaces. http://www.uci.cu ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
