captureVideo() returns video in 480x320 on ios

The full issue is currently discussed here https://forum.ionicframework.com/t/media-capture-video-is-low-quality/103774/23

When using the method captureVideo(), the video is automatically set to 480x320 on ios

I am working on a ionic-angular project, here is a code sample :

// code sample
var options = { quality: 1,duration:180 };
this.mediaCapture.captureVideo(options).then(videodata => {
  console.log('start capture video');
  var i;
    for (i in videodata) {
       let options = {
          fileUri: videodata[i].fullPath
       };
       if (!this.platform.is('ios')) options['audioChannels'] = 1;
       this.videoEditor.getVideoInfo(options).then((videoInfo) => {
          console.log('video width : '+videoInfo.width);
          console.log('video height : '+videoInfo.height);
          // returns 480x320 on ios and 1920x1080 on android
       });
});

FYI : I'm developping on android, right now I'm helping a colleague for the ios version, and this is the last probleme to solve
