Playing a network streaming video using Qt MultiMedia and Widgets

Question

I am trying to build a simple qt application which will play a live video stream. The streaming video is not playing in my app. I have played a local file using qt but i can't play the live video stream. I have found this links but they didn't help me :-

Play a Live video Stream using Qt

Qt Stream IP Camera Video

Here is the code:-

#include <QApplication>
#include <QtMultimediaWidgets/QVideoWidget>
#include <QtMultimedia/QMediaPlayer>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QMediaPlayer *player = new QMediaPlayer;
    QMediaContent *mc=new QMediaContent(QUrl("http://192.168.42.129:8080/video"));
    player->setMedia(*mc);
    player->setVolume(50);
    QVideoWidget *videoWidget = new QVideoWidget;
    videoWidget->resize(700,700);
    videoWidget->show();
    player->setVideoOutput(videoWidget);
    player->play();

    qDebug()<<player->availableMetaData()<<player->currentMedia().canonicalUrl();
    qDebug()<<player->errorString();

    return a.exec();
}

I am using an app in my android phone to stream the video. The streamed video is playing on VLC media player, Opera Browser, Mozilla Browser. I have tried different formats like MOV, MKV, WEBM (The app says MP4 is not supported by the hardware renderer in my phone). Please help, stuck on it for a while.

EDIT - I don't want to use any other library like libVLC because I noticed the streaming video is lagging in vlc media player. It may have some performance issues.

Answer 1

I figured out a way around. I was not able to do with QMultimedia widgets. I had to use external libraries like libvlc or vlc-qt. They have good APIs and generally have no performance issues (as I thought previously). They are very easy to integrate with Qt(and its widgets).
