Use this function to save the decoded closed captioning data coming from a LEAD MPEG2 decoder. Closed Captioning data can be embedded inside an MPEG2 Video Elementary stream.
The Convert object can decode such data and write it to a file. Files can be saved to two different formats:SubRip (SRT) and text.
SRT files contain the subtitles along with the timing information that specifies when to display each subtitle. By default IltmmConvert::SetClosedCaptioningTargetFile saves to the SRT format. To set it to use the default, set the flags to zero or ltmmClosedCaptioning_Default. Find more information about the SubRip format by searching for "SubRip" on the internet.
Closed captioning data can also be saved as text. To save the closed captioning information as a text file, set flags to ltmmClosedCaptioning_Text.
For a list of predefined values, refer to ltmmClosedCaptioning_Flag constants.
