configuring for video seeking? - using projekktor media player

[ura]

i am creating a plugin for the elgg open source social networking framework,
that adds the projekktor media player (http://www.projekktor.com/) to elgg.
i am so far unable to get projekktor to seek video/audio files on the
webserver (tested using nginx 1.5.13 + 1.7).
i have asked on the projekktor forum and did not find a resolution there.

essentially, i have the mp4 and flv add-ons activated for nginx and i have
added the following to my site's config:

	# streamable mp4
    location ~ .mp4$	
	{
		mp4;
		mp4_buffer_size 4M;
		mp4_max_buffer_size 20M;
		gzip off;
		gzip_static off;
		limit_rate_after 10m;
		limit_rate 1m;
	}
	
	# streamable flv
    location ~ .flv$	
	{
		flv;
	}	

...

i also looked enabling the pseudostreaming option for projekktor, however i
was informed that i didn't need to do that via the projekktor forum and that
if the server supported the appropriate streaming method then the player
would use it.

does anyone know what i am missing here?

thanks
