This graph shows basic video-only rendering. The DV Video Decoder converts the DVSD DV video
stream to the YUY2 format required by the video renderer. The Smart Tee allows a capture stream
to be connected as well as the preview stream. It is optional in this particular graph; however, the
normal graph-building process usually inserts a SmartTee automatically.
Figure 75. Basic video-only rendering
This graph renders both audio and video. The Capture Filter’s DV A/V Out pin is used instead of the
video-only pin. A DV Splitter is added to the graph to split the interleaved A/V stream into separate
audio and video. The audio stream is standard PCM audio which can be directly rendered by a
standard rendering filter. The video stream is in DVSD format and as before is converted to YUY2 by
the DV Video Decoder before rendering.
Figure 76. Audio and video graph
This graph combines video capture with video preview rendering. Here the Smart Tee becomes
mandatory to split the single video stream into two.
Figure 77. Video capture with video preview rendering
The following graph is a combination of elements described in the previous graphs.
