Detailed Description
Real-time shooting preview window.
When shooting a video, connect the live window with the capture preview and preview the scene in real time. After the shooting is completed, the live window is connected to the created timeline. And the video which has shooted can edit as needed, and then compile and output a video .mov format file.
- Warning
- For NvsLiveWindow class，all public API must be implemented within UI thread！！！
