CBaseRenderer::m_ObjectCreationLock member
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Lock to protect the creation of objects inside the filter. The filter holds this lock when it creates the input pin (CBaseRenderer::m_pInputPin) or the CRendererPosPassThru object (CBaseRenderer::m_pPosition). This lock prevents multiple threads from attempting to create one of these objects at the same time.
