It's work compiled succesfully for me after adding "multimediawidgets" library in.Media Player demonstrates a simple multimedia player that can play audio and or video files using various codecs.

To run the example from Qt Creatoropen the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example. To give the application playlist capability we also use a QPlayList object.

To activate the various functions such as play and stop on the dialog, the button clicked events emit the play and stop signals, which are connected to the play and stop slots of QMediaPlayer. The example also allows us to change various video properties by means of the QVideoWidget object. We can go to Full Screen mode with a single button click, and back again. Or if we press the "Color Options" dialog button we can have access to more subtle influences.

The dialog has a set of sliders so that we can change the brightness, contrast, hue and saturation of the video being watched. The connect statements are in pairs so that changes to either the user interface widget the relevant slider or the QVideoWidget object will update the other object.

Each scene in the flickable list is implemented in its own QML file - for example the video-basic scene which just displays a static VideoOutput in the center of the screen is implemented in the VideoBasic. As you can see from the code, this makes use of a type of inheritance; a VideoBasic item SceneBasic describes the structure and behavior of the scene, but is agnostic of the type of content which will be displayed - this is abstracted by Content.

This approach is used to implement many of the other scenes - for example, "repeatedly slide the content from left to right and back again" is implemented by SceneMoveon which VideoMove and CameraMove are based.

Depending on the value of the contentType property in the top-level scene instance, the embedded Content item creates either a MediaPlayer or a Camera item.

The QML painting rate is calculated by the FrequencyMonitor class, which turns a stream of events received via the notify slotinto an instantaneous and an averaged frequency:. All that remains is to connect the afterRendering signal of the QQuickView object to a JavaScript function, which will eventually call frequencyItem. Example project code.

I want to create an application through which i need to play a video file with audio need to play almost all kinds of videos. My Project Description: 1. Need to play a video in a thread 2. In an another thread. Parallely, need to capture the webcam video and need to process the webcam frames with Opencv algorithms which plots the graphs.

Planning to duplicate the youtube video application. I have to use threads as well. And opencv supports QT. What have i done: Used Java Media Framework to playback which fails as it dosn't support all the formats. If you use Qt version 5 you can use QMediaPlayer and with version 4 you can use phonon module look at examples, if i remember correctly they contain a simple video player.

Wellif you are willing to use Qt5 then Multimedia module has everything you need. You can use the same video surface to play video and and display web cam frames. There are simple examples in Qt5 multimedia widgets example directoryyou can refer. Learn more.

You can do the standard playback tasks like playpauseand stopbut also set a playback volume and seek - if the media and backend supports seeking.

VideoPlayer is provided for convenience and removes the need to create a media graph with a MediaObjectAudioOutputand VideoWidget. If you need functionality not supported by the player, you can build this graph yourself. Note also that most of the functions in this class are asynchronous. For instance, a media source may not play immediately after you call the play function. Constructs a new VideoPlayer instance with the specified parent. Constructs a new video widget with a parent using Phonon.

VideoCategory as its category. Returns true if it is currently paused; otherwise returns false if it is currently playing or stopped. Returns true if it is currently playing; otherwise returns false if it is currently stopped or paused. Starts pre-loading the media data from the specified source and filling audio buffers in the backend. When there's already a media playing or paused it will be stopped the finished signal will not be emitted.

Plays the media from the given source. Starts playback as fast as possible. This can take a considerable time depending on the URL and the backend. If you need low latency between calling play and the sound actually starting to play on your output device you need to use MediaObject and be able to set the URL before calling play.

Note that. Seeks to the requested time. Note that the backend is free to ignore the seek request if the media source isn't seekable; you can check this by asking the media object of the VideoPlayer.

The call is asynchronous, so currentTime can still be the old value right after this method was called. If all you need is a slider that shows the current position and allows the user to seek, use the class SeekSlider.
