color magnification

[jianghongsun]

hi,Thank you for your sharing.When I load another video for color enlargement, I can't read the video information correctly. This problem occurs in the 330 lines of mainwindow.cpp file.
ui->progressSlider->setValue(video->getNumberOfPlayedFrames()
* ui->progressSlider->maximum()
/ video->getLength() * 1.0);
0x00007FF76800031B 处有未经处理的异常(在 excutable.exe 中): 0xC0000094: Integer division by zero.

Thank you for your reply!

Please refer to #3 first and see whether you're facing the same issue.

It's been a long time and I already forgot how to build the application.

Did you tried executing qmake before running make?

If it helps, you can take a look at my note on the qmake workflow: https://www.hahack.com/wiki/qt-basic.html

Thank your.I found my mistake.

Maybe you can help me improve the README on how to build the application.

PR is welcome. ;-)
