It looks like an issue with the encoding of the mp4 file.

When I access the file directly at it also looks to have no video. I would recommend re-encoding the video.

I have reduced the video resolution from 1920x1080 to 640x360 and it worked.

Why jwplayer cannot play the 192x1080 on html5 and on flash I see blank screen but I can hear the sound?

How can I fix that?
