CSourceStream.ThreadProc 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 ThreadProc method is the thread procedure for the worker thread. This method implements the pure virtual CAMThread::ThreadProc method.
Syntax
virtual DWORD ThreadProc();
Parameters
This method has no parameters.
Return value
Returns 0 if the thread completed successfully or 1 otherwise. If the return value is 1, the thread's resources might still be allocated.
Remarks
This method waits indefinitely for thread requests, by calling the CAMThread::GetRequest method. If it receives a CSourceStream::Run or CSourceStream::Pause request, it calls the CSourceStream::DoBufferProcessingLoop method. The DoBufferProcessingLoop method pushes data until it receives a CSourceStream::Stop request. The thread procedure exits when it receives a CSourceStream::Exit request.
