Qurl gst-pipeline error - DirectShowPlayerService::doSetUrlSource: Unresolved error code 0x800c000d()
-
For Windows 10 platform, I am trying to play udp network video stream using QMediaPlayer and setmedia. I am using QUrl and gst-pipeline to decode video stream. I have added code snippet below. I am able to build successfully, but gives below error during run.
Error in Qt Application Output: DirectShowPlayerService::doSetUrlSource: Unresolved error code 0x800c000d()
mainwindow.cpp code snippet :
QMediaPlayer* player = new QMediaPlayer; QVideoWidget* vw = new QVideoWidget; player->setVideoOutput(vw); player->setMedia(QUrl("gst-pipeline: udpsrc port=60004 ! tsdemux name=demuxer demuxer. ! queue ! h264parse ! decodebin ! queue ! videoconvert ! videoscale ! autovideosink")); vw->setGeometry(100,100,300,400); vw->show(); player->play();

Please share solution if anyone has already faced such issue.

Hi and welcome to devnet,
Did you build the QtMultimedia GStreamer backend ?

@SGaist ,
I want to play video, received through udp network stream. I am receiving video in TS format over udp. I want to play it in Qt's window for Windows10 platform. Please advise the possible solutions. I have installed gstreamer in the system. Then how to build QtMultimedia gstreamer backend ? Any other solution to play udp network video stream for windows platform ?
