Bom basicamente, quando vou executar um vídeo direto pela url dele ele executa normalmente, porém em alguns dispositivos android (pelo menos no meu J2) não da pra copiar a url do player, então fiz um sistema simples para pegar a url do atributo src da tag vídeo para usar no src do player, só que sempre da este maldito error:
