Hi all,
I am working on connecting a webcam that streams mjpeg through a url source. I
have been using the qml Video component to stream and display the webcam feed.
When I build and run my program on Linux with GStreamer installed the video
feed will display just fine. However when I compiled the same code in VS13 no
visual feed is displayed. I added some code for debugging to verify if there
were any errors loading, connecting or displaying the feed but the error code
returned as "MediaPlayer.NoError - there is no current error".
My original suspicion would be that I am missing a media service component to
display the video feed however if that were the case the error code should
return as "MediaPlayer.ServiceMissing - the video cannot be played because the
media service could not be instantiated.". I do not have GStreamer installed on
Windows but I am also unsure if this is required for both Linux and Windows or
if the media services used by Qt differ between these platforms. QML provides
no other error messages when running the application. When the application
window is closed the program continues to run unless I force quit via the
terminal in which case the terminal displays this message : "QObject::~QObject:
Timers cannot be stopped from another thread".
Some relevant code:
import QtMultimedia 5.7
import QtQuick 2.7
import QtGraphicalEffects 1.0
Item {
id: root
height: 200
width: 200
Video {
id: video
height: 40
width: 40
source: "myURL"
autoPlay: true
}
}
If anyone has any idea as to what I am missing or if I am implementing
something incorrectly your help and feedback would be very much appreciated.
