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.

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.
