Seeking with QMediaPlayer
This is not a question but a solution. I tried to play a sound file not at the beginning but with an offset of 20 seconds.
The following fails:
@player = new QMediaPlayer(this);
player->play(); // music can be heard
qDebug() << player->isSeekable(); // is always false
player->setPosition ( 20*1000 ); //does not work@
It does not work because QMediaPlayer works asynchronously.
As soon as the seek operations are delayed everything works as intended. For example:
qDebug() << player->isSeekable(); // true
player->setPosition ( 20*1000 );
This should be mentioned in the documentation. For Qt we have the "fantastic new online version":http://developer.qt.nokia.com/doc/qt-4.7/ where annotations can be posted. Unfortunately Mobility is not yet integrated.
You could always make this into a little wiki article here on QtDevNet until such time as the mobility stuff is added to the docs here. Then you could add a docnote that links to the wiki article.
On popular request here is the article in the wiki. As a bonus it comes with a blocking setMedia() method.
could any one explain me this thing coz i also want o seek a video and i didnt get it how it works in the 2nd code which is written above
