Livecoding video effects with Qt5

A few minutes of 720p livecoding video effects in Qt5/QML with my "quint" application (https://gitorious.org/quint) using a 720p version of Big Buck Bunny (http://www.bigbuckbunny.org/) as raw material.

Qt5 (http://qt-project.org) includes support for OpenGL shader effects on video streams using the QtMultimedia MediaPlayer & VideoOutput QML Items.

A library of standard shader effects - QtGraphicalEffects - is available from https://qt.gitorious.org/qt-labs/qtgr... (see also http://labs.qt.nokia.com/2012/02/02/q...). Shown in the video are a few of those effects: HueSaturation, ZoomBlur and DropShadow.

Everything is running on a low-end netbook PC (Acer Aspire One 522 with AMD C-50/Radeon 6250) using Ubuntu.

This excellent!

But I can't get it to compile in Windows. Did anyone succeeded?

Thanks in advance for sharing.

I think he meant that he would have liked to see the screen captured somehow else than with a video camera

According to the video description: "Everything is running on a low-end netbook PC (Acer Aspire One 522 with AMD C-50/Radeon 6250)"

So, just about any computer can run that.
