Comment (by Krieger):

 It may take too long because MJPEG streams don't include timestamps, and
 by default they are generated by ffmpeg like there's 25 FPS.
 Try ffmpeg -use_wallclock_as_timestamps 1 -i http://...

 Try also -probesize 32 -analyzeduration 0 or something like that to reduce
 probing period.
