Hello forum,

By using Multimedia toolkit and Medical Imaging toolkit is this possible to load any mpg file and convert them to bitmaplist. But this conversion must be inmemory i.e. without storing images on drive.

For e.g.

LoadFile ( Myfile.mpg)

LBitmapList BitmapList =  ConvertToBitmapList();

Please suggest any solution so that I can convert mpg file to a list of bitmap.

 

Thanks

You can insert a LEAD Video Callback filter, which gives direct access to all video frames when playing the MPEG file. In your callback function, you can copy the image data to LBitmapBase class, and then you can insert this bitmap to the LBitmapList by using the LBitmapList::InsertItem function.
Please check the "C++ Video CallBack Demo" that ships with the LEADTOOLS Multimedia SDK. You can find the demo and the code in this folder:
<LEADTOOLS Multimedia folder>\Examples\Ltmm\Cpp\Callback
