[Mac] How to use QuickTime to open a Movie and set the frame to QImage?

**Gonzalez** · 29th October 2006, 22:12

Hi to all ,

I am now using a Mac 10.4.8 with Qt 4.2.

I would like to know how to open a Movie File using QucikTime library and then put the frame into QImage.

Thanks.

It's rather a QT question, not a Qt one

Anyone can help me?

If you don't insist on using QuickTime library, you can use (for example) libavcodec from ffmpeg package and decode the frame you want and put it into QImage. If you insist on using QuickTime directly, I suggest you ask that question on QuickTime forums as this has nothing to do with Qt. If you have the image bitmap, putting it into QImage is easy - there are QImage constructors which take the image data as an argument.

Well , i am now interesting in using ffmpeg with Qt 4 , any tutorial or documentation how to use ffmpeg in Qt 4?

Thanks.

I managed to create a widget showing the video stream from within the movie by following a tutorial I found in the net, but was unable to receive sound output, so I can't help you much with a complete solution yet.
