Some changes are questionable, some need improvement, see a bit below.

Also check if you need a casting.

The media subsystem is strict about 80 character limit. Yes, the original is
also long, but this makes it worse. Same for other similar cases.

Here and in some other places out of a sudden the style is changed to "one
parameter per line", why?

While there is no comma in the original, this is not a terminator entry, so
while at it, add trailing comma.
