Transformer demo: support selecting all media MIME types

Browse Source 
It's useful for development and debugging to select a local image
or audio (only) file as well as a video file in the transformer demo
app.

I tested manually that you can select a local video, audio and image
but not e.g. a pdf with the main "choose local file" picker and only
an image with the choose local image picker for the bitmap overlay
demo.
