Disable transcoding when reading content URIs

Browse Source 
Before this change, we list the formats for which we don't
want transcoding. This change disables transcoding altogether.

This was tested by checking that transcoding takes place on a
short camera recording only when the added flag is not present
(and AndroidManifest does not declare support for HEVC).
