Comment (by oromit):

 For all I'm aware, the concat demuxer can only be used if the files it's
 concatenating would produce a valid media file if concated naively with
 cat.
 It will take it, but produce technically invalid output and the mileage
 with that may vary.
 So a bunch of otherwise unrelated sources need the concat filter and in
 turn re-encoding.
