Chapter 6: Video Driver Topics
Application notes
Windows Media Player will not play back an AVI
file with an embedded CC stream. The above
GraphEdit filtergraph will play back an AVI file
containing a video stream plus a CC stream, with
the CC rendered on the video.
AMCap, the DirectShow sample capture app, will
render closed captions in its preview window. It
will also capture them to AVI (But, remember,
Windows Media Player will not play back the
CCs.). There is a “Closed Captioning” item in the
Capture menu. There are two restrictions:
You have to turn off Preview in the AMCap
Options menu before starting capture;
otherwise, AMCap will say, “Cannot start graph”.
AMCap does not capture audio and CC at the
same time – although from the points of view
of DirectShow and the driver, this is perfectly
possible. You have to turn off “Capture Audio” in
AMCap’s Capture menu.
