Description

While trying to create frame-advance functionality, found that setting current time on iOS does not work as expected. To reproduce, try the following: *Alloy*

<Alloy>
  <Window title="Player" id="vidPlayerWindow">
    <View class="container" id="view">
      <VideoPlayer id="theVideoPlayer" autoplay="true" url="[insert URL of your video here]" />
      <View id="controlPanel">
        <Button id="btnPlayPause" />
        <Button id="btnFrameAdvance" />
      </View>
    </View>
  </Window>
</Alloy>

Titanium Controller

var frameRate = 240.0; // frames per second - Also try 30 and 24 and 15, 
var msPerFrame = 1000.00 / frameRate; // how many MS per frame

Ti.API.debug ("Frame advance will advance by " + msPerFrame + "ms");

$.btnPlayPause.addEventListener('click',function(e){
  //Pseudocode
  // if $.theVideoPlayer.isPlaying, $.theVideoPlayer.pause();
  // Or if not, .play()
});

$.btnFrameAdvance.addEventListener('click',function(e){
    var currentTime = $.theVideoPlayer.getCurrentPlaybackTime();
    var newTime = currentTime + (msPerFrame);
    Ti.API.debug('current Time ' + currentTime + 'ms to new time ' + newTime + 'ms');
    $.theVideoPlayer.setCurrentPlaybackTime(newTime);
});

And finally output log: {noformat} [DEBUG] Frame should advance by 4.166666666666667ms each press {noformat} I open video player and then about a second later hit pause. Then I hit the advance button. {noformat} [DEBUG] current Time 1181.8333333333333ms to new time 1186ms [DEBUG] current Time 1061.6666666666667ms to new time 1065.8333333333335ms [DEBUG] current Time 1065ms to new time 1069.1666666666667ms [DEBUG] current Time 1061.6666666666667ms to new time 1065.8333333333335ms [DEBUG] current Time 1065ms to new time 1069.1666666666667ms [DEBUG] current Time 1061.6666666666667ms to new time 1065.8333333333335ms {noformat}

[~jvngd] Hello I've tested the method using a classic app and it all seems to work as expected. Could you please try this using 5.4.0, you can download the sdk using the [build server](http://builds.appcelerator.com.s3.amazonaws.com/index.html#5_4_X) . Thanks. Demo Code:

   var win = Titanium.UI.createWindow({
       title : 'Video View Demo',
       backgroundColor : '#fff'
   });
   var previouseQuator = 0;
   
   var videoPlayer = Titanium.Media.createVideoPlayer({
       top : 2,
       autoplay : true,
       backgroundColor : 'blue',
       height : 300,
       width : 300,
       mediaControlStyle : Titanium.Media.VIDEO_CONTROL_DEFAULT,
       scalingMode : Titanium.Media.VIDEO_SCALING_ASPECT_FIT
   });
   
   var begining = Titanium.UI.createButton({
      title: 'Jump to begining',
      bottom: 10,
      width: 100,
      font: {fontSize: 12},
      left:10,
      height: 50
   });
   
   var middle = Titanium.UI.createButton({
      title: 'Jump to middle',
      bottom: 10,
      width: 100,
      font: {fontSize: 12},
      middle:-10,
      height: 50
   });
   
   var end = Titanium.UI.createButton({
      title: 'Jump to End',
      bottom: 10,
      width: 100,
      font: {fontSize: 12},
      right:10,
      height: 50
   });
   
   begining.addEventListener('click',function(e)
   {
      videoPlayer.setCurrentPlaybackTime(0.0);
   });
   
   
   middle.addEventListener('click',function(e)
   {
      var duration = videoPlayer.duration/2;
      videoPlayer.setCurrentPlaybackTime(duration);
   });
   
   
   end.addEventListener('click',function(e)
   {
      var duration = videoPlayer.duration;
      videoPlayer.setCurrentPlaybackTime(duration);
   });
   
   
   
   videoPlayer.url = 'http://clips.vorwaerts-gmbh.de/VfE_html5.mp4';
   win.add(videoPlayer);
   win.add(begining);
   win.add(middle);
   win.add(end);
   win.open();
