IMSVidStreamBufferV2SourceEvent::ContentPrimarilyAudio method (segment.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
Fired when an SBE2 source filter receives a STREAMBUFFER_EC_PRIMARY_AUDIO event, which is fired through the IMSVidStreamBufferSourceEvent3 interface, and indicates that SBE is processing primarily audio data.
Syntax
HRESULT ContentPrimarilyAudio();
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
A STREAMBUFFER_EC_PRIMARY_AUDIO event is sent if video samples are captured at a low frame rate. This event generally occurs with audio services on a DVB stream, but it might also indicate a problem with capturing or encoding the video.
This event applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 or later.
