ask for helping play video on ios8+

[杨恒]

Hi,sorry to trobule you,but I has a urgent problem when I play local video on 
ios8+.
the development is cordova@5.3.1  and the version of ios simulator is 8.4.
now I want to play local a video using html tag "video" after download and 
unzip ,but the result is just a gray play button and can't play.
I had converted to cdvfile://  and tried to use native path,both  are the same.
and the code here

        cordovaFileTransfer.download(uri,targetSource)
          .then(function(entry){
            var desDIr=self.filePath+'/'+self[type]+'/'+o._id;
            scope.core.textLabel="解压中。。。";
            scope.core.progress="";
            cordovaZip.unzip(targetSource,desDIr).then(function(data){
              resolveLocalFileSystemURL(desDIr+'/running.mp4', function(entry) {
                var nativeUrl=entry.toInternalURL();
                o.videoUrl= nativeUrl;
                o.coverUrl=desDIr+'/cover.png';
                if(type=='star'){
                  o.courseUrl= desDIr+'/course.json';
                  o.coverUrl=desDIr+'/control.json'
                }
                d.resolve(o);
              });
            },function(err){
              console.log(JSON.stringify(err));
              d.reject(err);
            })
          },function(err){
            console.log(JSON.stringify(err));
            d.reject(err);
          },function(notify){
            scope.core.textLabel="下载中";
            scope.core.progress=Math.round((notify.loaded / notify.total) * 
100)+"%";
          })
 

the video code here
        <video controls="controls" width="400px" height="250px" preload="auto" 
webkit-playsinline="true">
          <source src="{{config.src}}" type="video/mp4" />
        </video>

and also add 
    <access origin=''cdvfile://*"/> to config.xml


So can you help me ...waiting for you
