Not quite. Your first console output indicated that your mp4 file
contained H.264 video. These more recent console outputs contain "mpeg4
(Simple Profile)" which I doubt are playable in JW Player.

With what device(s) are you attempting to watch the video? As mentioned
elsewhere in this thread if you are also targeting some mobile devices
you may have to re-encode to their specs such as with "-profile:v
baseline -level 3.0" and perhaps "-refs" (since "-level" does not set
it, IIRC) and other limitations such as frame size with "-s" or the
scale filter.

This is ignored if you are stream copying.
