Detailed Description

Track compound caption.

Track compound captions are compound caption that is superimposed on the video, each compound caption may composed of several sub-captions. When editing a video, users can add or remove track compound captions and adjust the captions position. User can also set its properties such as font family, text color, etc.

Warning
In the NvsTrackCompoundCaption class, all public APIs should be used in the UI thread!!!
