COutputQueue::ThreadProc (Compact 2013)

  • Article

3/26/2014

Implements the thread that sends samples downstream.

Syntax

DWORD ThreadProc( );

Parameters

None.

Return Value

Returns zero when DirectShow terminates the thread.

Remarks

This is the main thread procedure for the class, which is called from COutputQueue::InitialThreadProc.

It sends a sample or a batch of samples to the connected input pin (depending on the m_bBatchExact, m_nBatched, and m_lBatchSize data members) when conditions are met.

Otherwise, it increments the m_lWaiting data member, while holding the critical section and waits for m_hSem to be set (not holding the critical section) to continue.

Requirements

Header

dshow.h,
Streams.h

Library

ole32.lib,
Ole32auth.lib,
Strmbase.lib,
Strmiids.lib,
uuid.lib
