Lets the user select a video from the mobile device's video gallery and returns a video identifier.
ui.Interface.frontCall("mobile", "chooseVideo",
[], [path])
The "chooseVideo" front call starts the system's video chooser (the device's video gallery), allows the user to choose a video, and returns the path/URL on the mobile device of the selected video.
If the user cancels the video chooser, NULL is returned.
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.
