IMFQualityAdvise::SetDropMode method (mfidl.h)

  • Article

Sets the drop mode. In drop mode, a component drops samples, more or less aggressively depending on the level of the drop mode.

Syntax

HRESULT SetDropMode(
  [in] MF_QUALITY_DROP_MODE eDropMode
);

Parameters

[in] eDropMode

Requested drop mode, specified as a member of the MF_QUALITY_DROP_MODE enumeration.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
 The method succeeded.
MF_E_NO_MORE_DROP_MODES
 The component does not support the specified mode or any higher modes.

Remarks

If this method is called on a media source, the media source might switch between thinned and non-thinned output. If that occurs, the affected streams will send an MEStreamThinMode event to indicate the transition. The operation is asynchronous; after SetDropMode returns, you might receive samples that were queued before the transition. The MEStreamThinMode event marks the exact point in the stream where the transition occurs.
