Yeah, that's an interesting request. Would it be for just one movie or for all movies? The problem with the FLV features right now is that all the configuration, with the exception of thumbnail width and height, are global settings. The easiest thing for me to do would be to add a static variable "extra_flash_params" to the FLV class and have it add whatever you put in there to the swfobject call.

But that would affect every video, unfortunately.

Yeah, i really want to do an overhaul on all the video stuff, and eventually make it its own module. I didn't expect it to be so popular, with the FFMPEG requirement and everything, but that seems to be working out great. That offers a lot of functionality that has yet to be harnessed. I could definitely take the audio/video features to a place that would make SS a very competitive CMS.
