COutputQueue::m_hr 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
HRESULT value that indicates whether the object will accept samples. If the value is S_OK, the object will accept samples. Otherwise, it rejects samples.
Syntax
HRESULT m_hr;
Remarks
This member variable is used to coordinate activities across threads. If the downstream input pin rejects a sample, or if the object begins flushing, the value is set to S_FALSE or an error code. The object will not deliver any more samples until flushing is complete, or until the COutputQueue::Reset method is called.
