Extras

Extras (Figure 35) are features of the AVStream driver that are new, not fully defined, or subject to change. Extras may also include workarounds to apparent DirectShow issues that are expected to be resolved fairly soon.

Figure 35. Extras

Extras should be expected to change more frequently than other aspects of the driver.

Timecode Video Marking	Refer to the Vertical Interval Timecode (VITC) section of this guide for
	more information.

Closed Caption	This control is a workaround to what we currently believe to be a
Timestamping	problem in DirectShow with capture of CC to AVI files. If you attempt
	to capture a CC character pair stream along with a video stream to an
	AVI file with Normal timestamping, the file becomes extremely large
	and the capture fails within a few seconds. AVI-Compatiblemode
	allows capture of CC to AVI. Unfortunately, the problems with
	timestamping mean that time synchronization between the video and
	closed caption streams depend on their physical interleaving in the file,
	so that time synchronization is quite poor. We do not have a
	workaround for this at this time. For all applications other than capture
	to AVI, this control should be set to Normal. WME9 among others
	requires the Normal setting if CC is used.
