Should this be a NOTREACHED, or just a DVLOG() if we are falling back to
software decoder in these cases? Would this be a normal case or a result of a
bug to call this with is_encrypted=true? If the latter, would we know if VDA
supported encrypted content before attempting to Initialize() in order to avoid
calling it?

Currently we are only initializing VDA on Android for encrypted stream. This is
to prevent unnecessary delay and complexity on other platforms. We can always
change this in the future when we have more VDA supporting encrypted streams.
