in windows you have to use the winapi to show avi file. search on the codeproject or msdn for code examples. on linux look how mplayer does it.

Use QX11EmbedContainer (http://doc.trolltech.com/4.3/qx11embedcontainer.html) with mplayer passing -slave and setting the window id in the mplayer arguments. It 's pretty straightforward to achieve this.

The following is from the qxmp (http://www.xm1math.net/qxmp/index.html) video player sources illustrating a possible way to achieve that:


QX11EmbedContainer *container=new QX11EmbedContainer(ui.frame);
container->resize(w,h);
mp=new QProcess(container);
connect(mp, SIGNAL(readyReadStandardOutput()),this, SLOT(readPlayOutput()));
connect(mp, SIGNAL(finished(int)),this, SLOT(endPlayProcess(int)));
connect(mp, SIGNAL(started()),this, SLOT(startTimer()));
command=otherOptions+mplayerOptions+" -wid "+QString::number(container->winId())+" -slave "+playfile;
mp->start("mplayer "+command);
