How to display live stream video from camera

[lajtu]

Hey, I'm streaming video from camera connected to Raspberry PI. The stream was made with:

http://pimylifeup.com/raspberry-pi-webcam-server/

so it's available on some server port :3000 (e.g. 192.168.0.1:3000). When opening browser on that address there is just plain video.

I would like to display that video stream in QML. I see 2 approaches:

1. Using WebView but apparently WebView doesn't display anything when using my specific url (192.168.0.1:3000)
2. Using Qt Multimedia like Video {} component. Unfortunately I think it first requires to download video file like .avi, .ogg or other and then play it but it's a stream so I don't have finite video file!

What would be your approach ? Can it be achieved or my stream service is not compatibile with Qt ?

Hi,

You can set the URL on the Video element. If that doesn't work, you could use QtGStreamer

Hope it helps

QtGStreamer

Is it for mobile as well ? I'm building cross-platform app

It should work on platforms that has GStreamer support

I checked out Video component and I received following error:

Is your video an MJPG stream? I've done that in a somewhat ugly way by connecting to the camera stream with C++ code, and feeding the video frames to QML with a QQuickImageProvider.
