VFW_E_CANNOT_RENDER
VFW_E_CANNOT_RENDER is a DirectShow HRESULT. The source may have opened successfully, but the graph builder could not complete a playback path to a suitable renderer. Missing demultiplexers, decoders, renderers or incompatible stream formats are common causes.
What to check
- Identify the stream type and test whether a source filter exposes separate audio and video pins.
- Inspect the available decoder and renderer chain for the application's process bitness.
- Build the graph step by step so the first failing pin connection identifies the missing or incompatible component.
A partial-render success code can be more informative when one stream renders and another does not; inspect graph events and individual pin connections.
