CSourceStream.OnThreadCreate method

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

The OnThreadCreate method is called when the streaming thread is initialized.

Syntax

virtual HRESULT OnThreadCreate();

Parameters

This method has no parameters.

Return value

Returns S_OK.

Remarks

The thread procedure, CSourceStream::ThreadProc, calls this method when it first receives a CSourceStream::Init request. The method does nothing in the base class. The derived class can override this method to perform thread initializations. If the derived class returns an error code, the thread exits with an error.

Requirements
