API for continue watching…

Hello everybody,

I have this code:

var wpvs_update_time_interval = 10;
jQuery(document).ready( function() {

    if( typeof(wpvs_video_tracking) != 'undefined' && typeof(wpvs_theme_ajax_requests) != "undefined" && wpvs_theme_ajax_requests.user != null ) { 

        if(wpvs_video_tracking.video_type == 'fvplayer' ) {
            if( typeof(wpvs_fv_flowplayer) != 'undefined' && wpvs_fv_flowplayer != null ) {
                wpvs_fv_flowplayer.on('timeupdate', function(data) {
                    if(data.seconds >= wpvs_update_time_interval && wpvs_update_time_interval != 0 ) {
                        wpvs_update_users_current_video_time(data.seconds, data.duration);
                    }
                });

                wpvs_fv_flowplayer.on('loaded', function(data) {
                    if(wpvs_video_tracking.start_at != null) {
                        wpvs_fv_flowplayer.setCurrentTime(wpvs_video_tracking.start_at);
                    }
                });

                wpvs_fv_flowplayer.on('ended', function(data) {
                    if(data.seconds >= wpvs_update_time_interval && wpvs_update_time_interval != 0 ) {
                        wpvs_update_users_current_video_time(data.seconds, data.duration);
                    }
                });
            }
        }

Can you tell me if I used the correct Flowplayer API and names?

Thanks,
Chris
