CTransformFilter::m_bQualityChanged member

  • Article

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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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

Flag that indicates whether the quality has changed. The first time that the filter drops a sample, it sends an EC_QUALITY_CHANGE event to the filter graph manager and sets this flag to TRUE. It does not send this event again until the filter stops and restarts, even if it continues to drop samples in the meantime.
