mp4 streaming/seeking works from firefox (fedora) and not from firefox (windows) (nginx 1.9.3)

[tunist]

i did explore that possibility for several days, but did not achieve
success. part of the problem is that the videos have dynamic privacy
settings applied to them and so PHP is used to decide which videos the
present user can view and which ones they cannot view. i looked at using
various directives in nginx to bypass this but never found a way to do it.
