[Development] Qt 5.5 for Android - More Regressions Since 5.3
Hi, Trying Qt-5.5 for Android, the following regressions since Qt-5.3 are still inside and break it: 1. QTBUG-44337 - [REG 5.3-5.4] Android: QFileDialog for Save Keeps Save Button Disabled until the filename contains a dot 2. QTBUG-44271 - [REG 5.3 -> 5.4] Android: QFontComboBox Broken and even worse: 3. QProgressDialog instances are shown immediately on allocation and even explicit hide is not helping (Android 4.4.2, Nexus-7-2013) This is a regression since 5.4 Does anybody cares? If yes, I will open the issue. In Qt-5.3.1 all the above was working properly. IMHO, Qt for iOS and Android requires serious "go for stability" instead the current run for more and fancy features. Still, it might be that my visibility is limited and other people do not feel so or sales consideration require more features ASAP and do not care the quality. Thank you.

Nope, because all I've got are 8 lines of code that don't even work properly.
The eglfs change segfaults when playing. The linuxfb change shows the video as
you can see in the picture I've taken.
A complete integration and test of the different platforms is needed before
reaching Gerrit.
Anyway, here you go. You can simply copy the lines manually and recompile.

Update #2 (sorry for spamming)
I patched qgstreamervideowindow.cpp and qgstreamervideowidget.cpp to support
the linuxfb platform.
It kinda works !!
Screenshot here: http://pasteboard.co/1JlYRT9l.jpg
Videos can be played hardware decoded with audio and video until the end.
It's definitely using the OMX plugin.
Some other issues raised like these:
pi@raspberrypi ~ $ ./player -platform linuxfb sintel-1280-surround.mp4
(player:2857): GLib-GObject-WARNING **: g_object_set_valist: object class
'GstFBDEVSink' has no property named 'force-aspect-ratio'
This plugin does not support setParent!
(player:2857): GLib-GObject-WARNING **: g_object_set_valist: object class
'GstFBDEVSink' has no property named 'force-aspect-ratio'
My goal is to play fullscreen, so probably I can manage to find a way on the
Linux FB.
In any case the issue is: QtMultimedia gstreamer-1.0 support has been written
around XCB.
No eglfs, linuxfb, directfb, etc.
Someone should have written it in https://wiki.qt.io/New_Features_in_Qt_5.5

Oggetto: [Development] The dark side of QtMultimedia - strikes back
Update.
The message "No m_videoSink available!" is clearly an alarm that something is
going wrong.
So I checked the code and...surprise !
The EGLFS platform is not even considered ! Well done !
Code extract from qtmultimedia/src/gsttols/qgstreamervideowindow.cpp line 59:
if (elementName) {
m_videoSink = gst_element_factory_make(elementName, NULL);
} else if (QGuiApplication::platformName().compare(QLatin1String("xcb"),
Qt::CaseInsensitive) == 0) {
// We need a native X window handle to be able to use xvimagesink.
// Bail out if Qt is not using xcb (the control will then be ignored by the
plugin)
m_videoSink = gst_element_factory_make("xvimagesink", NULL);
}
if (m_videoSink) {
...
}
else
qDebug() << "No m_videoSink available!";
I tried to add something like:
else if (QGuiApplication::platformName().compare(QLatin1String("eglfs"),
Qt::CaseInsensitive) == 0) {
m_videoSink = gst_element_factory_make("eglglessink", NULL);
}
The error message disappears, but I get a black fullscreen result.
I don't even see the player example UI.
I guess it depends on the compositing between the gst window and the main eglfs
window.
So I haven't gone any further.
I can tweak the player example to accept a filename from the command line and
play it automatically.
At least I can check if the video playback is OK in this way.
This is extremely sad. I thought the gst 1.0 support came especially for the
raspberry Pi, since the little dude cannot afford software decoding (thus the
need of OMX -> thus the need of gst 1.0)
I can try the same tests on Xorg, but it's out of my scope.
I don't want to use Xorg but instead I will use Wayland.
