  • The application calls the IGraphBuilder::RenderFile method to build a filter graph that renders a media file.

In this scenario, you notice that a memory leak occurs in the IGraphBuilder::RenderFile method.

Notes
  • This problem occurs even if the application has removed all the filters from the graph.
  • You can attach the Resource Leak Detector tool to the application to detect the memory leak.
