Comment (by ramitbhalla):

 I"m sure it would work (don't have acess to the dev right now) but I'm
 still asking a very FUNDAMENTAL question:

 is a JPEG stream a video stream? Then why it being marked as Video?

 A very simple questions. Here's one thing to consider, MOST applications
 using ffmpeg today would expect the standard MP4 file to return a single
 video stream.

 But with this build now it will break ALL those applications since the
 jpeg thumbnail is now bring tagged as a video stream as a result of which
 anyone using map 0:v will need to rewrite the app.

 So really - am asking again, why is a jpeg attachment being tagged a video
 stream?
