Lets the user take a video with the mobile device and returns the corresponding video identifier.
ui.Interface.frontCall("mobile", "takeVideo",
[], [path])
The "takeVideo" front call invokes the mobile device's camera to let the user take a video and returns the local path/URL to the video on the mobile device.
If the photo is canceled by the user, the front call returns NULL.
The value returned in the path variable contains a reference to the system location of the video on the mobile device. This path is platform dependent, and may change in future versions. Consider the path returned by this front call as an opaque local file identifier, and do not use this path as a persistent file name for the video.
Once the video identifier/path is known, it is possible to fetch the video file from the device to the program context with the fgl_getfile() API. The procedure is similar to fetching photos from the device. For more details, see the section about video handling on mobile devices.
To play the video, you can perform a "launchURL" front call, with the opaque path returned by this front call.
