CVideoTransformFilter.AbortPlayback method

  • Artykuł

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 AbortPlayback method is used to signal a streaming error. It sends an EC_ERRORABORT event to the Filter Graph Manager, and sends an end-of-stream notification downstream.
