I'm working on migrating my code from Qt 4.8.4 to Qt 5.1.1 and seemed to have run into a peculiar problem. Previously I was using the Phonon library's video widget to allow users to interact with the video. Since Phonon is no longer supported I was looking for a way to replace my Phonon widget via the Qt Designer but I found no replacement widget available. Does anyone know how we're supposed to go about porting this functionality?
If anyone has any insight, it is appreciated as always!
All the other answers provide very useful information, but since I was looking for a specific and functional implementation, I'm guessing people that stumble on this may be looking for one as well, so I'll post my code along with my thought process and a bit of background info of my setup.
videoWidget = new QVideoWidget;
player = new QMediaPlayer;
verticalLayout->addWidget(videoWidget);
player->setVideoOutput(videoWidget);
player->setMedia(QUrl::fromLocalFile("Resources\\videos\\example.m4v"));
videoWidget->show();
player->play();
So to go through this, basically in my project I have a widget that is a part of a stackwidget structure on which I have some QWidgets like playback control buttons, labels, etc, and I previously had my Phonon video player. I really really didn't want to generate it all programatically so I managed to find a solution.
The above code was located in this container widgets constructor. In the designer I have made a simple, empty verticalLayout, positioned and sized it to my liking. This allowed me to embed the QVideoWidget despite not having a interactive QWidget in the Designer. videoWidget, and player are declared as private in the container widget's header file.
