CBaseRenderer.Run 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 Run
method runs the filter.
Syntax
HRESULT Run();
Parameters
This method has no parameters.
Return value
Returns S_OK if successful, or an HRESULT value indicating the cause of the error.
Remarks
This method overrides the CBaseFilter::Run method. It performs the following actions:
- Calls the CBaseFilter::Run method.
- Commits the allocator. (See IMemAllocator::Commit.)
- If the previous state was stopped, the filter releases any sample it is holding. (The sample is no longer valid.)
- Calls the CBaseRenderer::StartStreaming method and returns the result. If a sample is pending, the StartStreaming method schedules it for rendering.
If the filter is not connected, it posts an EC_COMPLETE event immediately.
