Example of start_time and media_duration parameter

By the specifying the media_duration and start_time in case of fv creatioin with specified order, you can set the start time point and play time duration of each medias.

In the case of below map data

[ [
        { "id":"1", "lev":"1", "rx":"0", "ry":"0"},
        { "id":"2", "lev":"1", "rx":"0", "ry":"0", "st":"6","dur":"4"}
   ],
   [
        { "id":"3", "lev":"1", "rx":"0", "ry":"0", "st":"6","dur":"6"},
        { "id":"4", "lev":"1", "rx":"0", "ry":"0", "st":"6","dur":"8"}
] ]

If the fv time duration is set to 30 seconds, the fv which will be generated is represented as below image.

../_images/api_start_time-media_duration01.png
../_images/api_start_time-media_duration02.png

Because fv time duration is set to 30 seconds and each media time duration is less than 30 seconds, each media is played repeatedly from the start_time for media_duration between fv time duration.
