[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
Specifies the number of encoding passes that the encoder supports.
This property is read-only.
UINT32 (VT_UI4)
CODECAPI_AVEncCommonMultipassMode
This property is returned as a range of values. To get the supported range, call ICodecAPI::GetParameterRange.
Decoding latency is defined as the amount of data the decoder must buffer. For example, setting this property to VARIANT_TRUE on an MPEG video encoder limits the types of GOP structures the encoder can use.
To set the current encoding pass, set the AVEncCommonPassStart property.
