HRESULT GetMediaType(AM_MEDIA_TYPE** ppMediaType);

Parameters

  • ppMediaType
    Pointer to a pointer to the retrieved media type.

Return Values

Returns an HRESULT value. When a sample is received and there is no format change, this method returns S_FALSE.

Remarks

This member function implements the IMediaSample::GetMediaType method.

The member function makes a copy of the AM_MEDIA_TYPE structure and creates a task memory block to maintain the reference.

When you are done with the media type, free the memory block with the FreeMediaType utility function, and then free the entire media type with the Win32 CoTaskMemFree function.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements.
