I suspect that Ionic will not be a sufficient choice for a streaming app as "streaming" seems like it might require lower level APIs than Ionic will expose.
You might explore Xamarin, which also has somewhat of a WYSIWYG GUI editor; however, apps must be written in C#. Otherwise there's NativeScript and React Native, which do expose lower level device APIs. And of course there's Android proper, which will be the most versatile platform.
