RTSP Stream with QML

mkrr

Hello,

I'm trying to figure out, how is possible do a RTSP Streaming from IP Camera directly on Qml and with a good performance.

I can do it on my desktop computer, but it should work on a Embedded System. Actually I'm using a Colibri iMX6 to develop and this streaming should work in this environment.

The problem is about performance on iMX6. When we start the
stream, the Qml application is a little "lazy". We can percept this
on "onClick" events, screen change, flickable components, ... There
is somethink like a "delay" in the application.

I'm using QML and the components MediaPlayer and VideoOutput, with the following code:

MediaPlayer {
id: videoPlayer
source:: "rtsp://admin:admin@192.168.0.10/cam/realmonitor
?channel=1&subtype=0"
muted: true
autoPlay: true
}

VideoOutput {
id: camera1
width: 100
height: 100
anchors.horizontalCenter: parent.horizontalCenter
source: videoPlayer
}

I saw something about gstreamer plugins to qml, Vlc plugins, ... but I can't understand why specific qml objects to Video aren't with a good performance. I believe I can improve this.

What whould you do in this case? What you are doing for this kind of application?

Hi,

Something to take into account:

What is the framerate of the stream ?
what is the size of the streamed images ?

Maybe this can help?
