|
* vtkWin32VideoSource grabs frames or streaming video from a

|
* Video for Windows compatible device on the Win32 platform.
|
|
* @warning
|
|
* With some capture cards, if this class is leaked and ReleaseSystemResources
|
|
* is not called, you may have to reboot before you can capture again.
|
|
* vtkVideoSource used to keep a global list and delete the video sources
|
|
* if your program leaked, due to exit crashes that was removed.
