The link I provided shows you how to create a custom GStreamer pipeline where you can try to use a pipe so you can both show the stream on your device and have it streamed on the network.

Custom pipeline building in QMediaPlayer came in 5.12.2 like explained in the documentation.
However nothing stops you from using other means to create the pipeline.

As I already wrote, don't do that in that order.
Stream your camera using a dedicated software that will generate a real video stream.
Even if it's not simple, GStreamer allows you to show the feed locally and send it over the network at the same time.

Sample code of what ?
You do not even say what solution you want to implement.

@SGaist we have embedded device which has camera and GUI application and I want to view/control the liveview of that camera from my android/iOS application. So each video frames from my embedded device should transmit to mobile application.
Qmediaplayer is only to play the media source if I'm not wrong.

i want to use Gstreamer to stream the video over network(TCP). give some example code so that i can start.

Here you have an example using the command line to stream a video feed from a RaspberryPi. The streaming part will work the same on a computer.

Hello @SGaist, i just running the following commands to undertand Gstreamer on command line.
To send current screen to network:gst-launch-1.0 -v ximagesrc use-damage=false xname=/usr/lib/torcs/torcs-bin ! videoconvert ! videoscale ! video/x-raw,format=I420,width=800,height=600,framerate=25/1 ! jpegenc ! rtpjpegpay ! udpsink host=127.0.0.1 port=5000To receive:
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=JPEG,payload=26 ! rtpjpegdepay ! jpegdec ! autovideosinkhere its sharing my current screen using ximagesrc to network.
So how can i send only current camera live view through Gstreamer. whats the command for that? -
Did you even try to search for "GStreamer camera source" ?

Thank you @SGaist,
i tried below script on command line
gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw-yuv,width=640,height=480' ! x264enc pass=qual quantizer=20 tune=zerolatency ! rtph264pay ! udpsink host=127.0.0.1 port=1234Got below error.
(gst-launch-1.0:4420): GStreamer-WARNING **: 0.10-style raw video caps are being created. Should be video/x-raw,format=(string).. now. WARNING: erroneous pipeline: could not link v4l2src0 to x264enc0 -

The first hit for that search on DuckDuckGo gives several example pipelines to test with your own setup.
