What's the best aproach to play propietary video format on iOS and Android QML app?

[lqsa]

My app needs to play propietary video format. Now I'm playing decoding the propietary format to a QImage for each frame and using a QQuickPaintedItem derived class to show the video. This class is registered on QML to use it from there.

class VideoPlayer : public QQuickPaintedItem {
public:
	void paint(QPainter *painter) override;
private:
	QImage _frame;
}


void VideoPlayer::paint(QPainter *painter)
{
    painter->drawImage(0, 0, _frame);
}

Is QQuickPaintedItem a slow technique? exist another better aproach?

Hi,

What kind of proprietary format is that ?
Can something like ffmpeg read it ?

[lqsa]

No, ffmpeg can't read. It's a propietary format.

Depending on how you decode your video, you can consider implementing a QMediaService plugin for QtMultimedia that will provide the QMediaPlayer bits that are needed to render your video.

Is more quick than QQuickPaintedItem? Where can found any documentation and sample?

@lqsa Documentation and samples for QMediaPlayer? Here: http://doc.qt.io/qt-5/qmediaplayer.html, http://doc.qt.io/qt-5/qtmultimedia-multimediawidgets-player-example.html

Sorry, but in these links I can't find any documentation about QMediaService plugin and sample is with QWidgets.

You can take a look at the QtMultimedia sources.
