@edit

I also discovered that there is no "qmlgl" (qmlgloverlay, qmlglsink, qmlglsrc) in the system which should be provided by gstreamer1.0-plugins-good. I forced to build packet configurated for qt5 by add line in my local.conf:

PACKAGECONFIG:append:pn-gstreamer1.0-plugins-good = " qt5"

After that I have available qmlglsink and other. I still can't play video directly from file because effect is the same no image. I tried to build pipeline:

source: "gst-pipeline: filesrc location=/home/root/dillama_1080p.mp4 ! decodebin name=dec ! videoconvert ! qmlglsink widget"

I can't set required pointer to qml widget for qmlglsink. How do it?

@SGaist Ah, in that case, I'll give it a try. Would that also be the case with QAbstractVideoSurface, or would that one receive further-in frames if more time passes?

Processing takes about 250ms per frame on Android right now. I'm working on ways to speed that up, but the processing fps is going to be worse than the video file's fps for some time yet.

@GrecKo It does, but it seems to be a read-only reflection of the viewport set for the video frame objects that are coming through the videoSink. When I attempt to assign to it, I get the QML error: Invalid property assignment: "sourceRect" is a read-only property. The docs do not appear to reflect the fact that sourceRect is read-only. I am using Qt 6.3.

Looking at the source for VideoOutput (https://github.com/qt/qtmultimedia/blob/37c2d097eb5dd8671cc752dc920da11d66105905/src/multimediaquick/qquickvideooutput_p.h#L41), we can see that the Q_PROPERTY for sourceRect is read-only in both the 6.3 and dev branches.

I have had the thought of attempting to manually set the viewport of the QVideoFrameFormat of the frames coming through the VideoOutput's videoSink, but I haven't created a working solution for that strategy yet.

Hi,

A QMediaRecorder to the mix.

@dhirvonen said in VideoOutput + QQuickView::SizeRootObjectToView + Qt::PortraitOrientation:

@Charby

Even better (and much cleaner). After inverting the -camera.orientation it works beautifully. Thanks again.

VideoOutput { id: output source: camera objectName: "VideoOutput" filters: [ infofilter, videofilter ] anchors.fill: parent orientation: -camera.orientation }

Hi Mr,
I am having a similar project of yours, but do not understand the objectName property my VideoOutput does, is it because I use Qt5.15?

objectName: "VideoOutput"

Thanks!

Hello,
Got another problem though I have managed to cross compile Qt5 with gstreamer1.0 support it is unable to play HD videos on pi.
I checked using GST_DEBUG=3 and it seems like it still uses gstreamer0.10.
So Do anyone have got HD video playing on pi and can suggest me to get it playing??

How did you build QtGStreamer ?

Hi @kolegs,
How did you capture the frame ?

Hi and welcome to devnet,

You should rather bring this to the interest mailing list You'll find there Qt's developers/maintainers (this forum is more user oriented). Also take a look at the bug report system to see if it's something known
