You could just rip the RTMP stream itself, or whatever the source data is. Decompile the swf and check it out for yourself, or the source url for the video feed is probably provided in some lame xml config file. No need to write software around an entire browser to get your ocean feed.

Just turn on the Net Inspector in your favorite browser's debugger and start the stream; you'll probably see what url it's loading.

And hopefully it's not RTMPS!
