Property binding ngForIn not used by any directive on an embedded template – Ionic 2

Your are mistaken with angular1 syntaxes:

Instead of *ngFor="#media in medias",

you have to write *ngFor="#media of medias"

UPDATE – as of beta.17, use the let syntax instead of #. This updates to the following:

<div *ngFor="let media of medias">
