AVI
VTKExamples/Cxx/Untested/Video/AVI
Description
This example demonstrates how to make an AVI video. In this example, each frame of the video is a red rectangle moving across the frame incrementally.
Code
AVI.cxx
#include <vtkSmartPointer.h>
//#include <vtkJPEGReader.h>
#include <vtkImageCanvasSource2D.h>
#include <vtkAVIWriter.h>
int main (int argc, char *argv[])
{
//vtkSmartPointer<vtkJPEGReader> reader =
// vtkSmartPointer<vtkJPEGReader>::New();
vtkSmartPointer<vtkImageCanvasSource2D> source =
vtkSmartPointer<vtkImageCanvasSource2D>::New();
source->SetScalarTypeToUnsignedChar();
source->SetNumberOfScalarComponents(3);
source->SetExtent(0, 100, 0, 100, 0, 0);
vtkSmartPointer<vtkAVIWriter> writer =
vtkSmartPointer<vtkAVIWriter>::New();
writer->SetInputConnection(source->GetOutputPort());
writer->SetFileName("test.avi");
writer->Start();
for(unsigned int i = 0; i < 100; i++)
{
source->SetDrawColor(0,0,0,1); //black
source->FillBox(0, 100, 0, 100); //clear image
source->SetDrawColor(255,0,0,1); //red
source->FillBox(i, 20, 10, 20);
source->Update();
writer->Write();
}
writer->End();
return EXIT_SUCCESS;

Download and Build AVI
Click here to download AVI and its CMakeLists.txt file. Once the tarball AVI.tar has been downloaded and extracted,
cd AVI/build
If VTK is installed:
cmake ..
If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..
Build the project:
make
and run it:
./AVI
WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
