video duration convert from milliseconds to minutes seconds

phirestalker

I am writing a progrm that deals with video using qt and opencv. I get the current frames position as milliseconds and I want to convert it to minutes and seconds. I know the math and could do it manually, I was just wondering if there is a built in qt way to do it. Thanks

Hi! As long as your video is unter 24 hours long you can use QTime for this:

const int milliseconds = 12345;
QTime vTime(0,0,0,0);
vTime = vTime.addMSecs(milliseconds);
qDebug() << vTime.hour();
qDebug() << vTime.minute();
qDebug() << vTime.mSec();
