|
// .SECTION Description
|
|
// vtkWin32VideoSource grabs frames or streaming video from a
|
|
// Video for Windows compatible device on the Win32 platform.
|
|
// .SECTION Caveats
|
|
// 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.
