decode webview.dll , html 'object'

i have a dll named "webview.dll". its being used in a web page as HTML <OBJECT>. i was wondering if anybody could decode this DLL, and extract its behavior. [login to view URL] full scenario: I have a DVR Card, it has a "Web Server" integrated into its Console Software. While connecting to the DVR Card from a remote browser, It prompts to Install this DLL. the DLL object is a "Video Player".. it has the ability to Play the streams transmitted by the "Web Server". this is a captured stream the DLL is able to playback: [login to view URL] (network interface capture, directly from the socket) currently i try to playback this video file with several Engines, most of them have failed... the ones which did not fail , (MPlayer for example) .. showed corruption while playing it. i need to decode this DLL, and extract its ability to playback this movie stream as far as i can see, there are 2 options. option #1 : the object contains a customized CODEC, who have the ability to decode the stream. solution in this case would be... extracting that CODEC and apply it on an external Engine... (mplayer , mencoder , ffmpeg.. etc) and give them the ability to transcode the stream by thierself. option #2 : the object parses the stream differently, and uses a generic codec for decoding it. solution to this scenario... make a util , which i pipe into STDIN the stream of the socket - and then the util STDOUT the PARSED stream which is now generic to the Engines. (ffmpeg/mencoder..etc) thank you very much, pobel.
