Comment (by TheoMeister):

 mediainfo detects the jpegs correctly as attachment consisting of
 cover.jpg / small_cover.jpg / cover_land.jpg / small_cover_land.jpg
 whereas ffmpeg detects them as video stream which seams to be wrong to me,
 because it's not a video but a image attachment.

 Anyway: I want ffmpeg to encode video stream 0:1 and copy all the other
 streams. How can I tell ffmpeg to do so all at the same time? Or maybe I
 want to ignore some existing streams completely? I don't know of any other
 option than -map to select streams.
