Could an approach like this work? I would test it but thats for another task...
/**
* @ORM\Column(type="string", length=255, nullable=true)
*
* @Assert\NotBlank(message="Bitte wählen sie eine valide Datei.", groups={"textimage", "video"})
* @Assert\File(mimeTypes={ "video/mp4" }, groups={"video"})
* @Assert\File(mimeTypes={ "image/jpeg" }, groups={"textimage"})
*/
private $media;
So I have one media property on the entity which should work for two different types of media - seperated by validation groups.
Would be nice if this would work - anyone knows that? If not whats the correct approach for that?
